Provisioning Profile Does Not Include Required Speech Recognition Entitlement
I am building an iOS app with the App ID: com.echo.eyes.app I have a paid Apple Developer membership and have followed all correct procedures, including: Adding com.apple.developer.speech-recognition manually to the App.entitlements file Setting Info.plist keys for microphone and speech permissions Assigning my Apple Developer Team to the project Setting App/App.entitlements under Code Signing Entitlements Despite all this, Xcode automatic signing fails, and I receive the error: vbnet Copy Edit Provisioning profile 'iOS Team Provisioning Profile: com.echo.eyes.app' doesn't include the com.apple.developer.speech-recognition entitlement. I am unable to add the entitlement via the Capabilities section, and no method I try will allow provisioning to succeed. Please update this App ID to include the required entitlement in the provisioning profile. This issue is preventing all voice recognition functionality. Thank you.

deduplicated_symbol error
HI, I have a Swift UI app in the mac appstore in the upcoming release we have made lots of changes and it is working fine in debug mode but in production with testflight or direct distribution we are getting the following crash while working in the app. this is happening in the rendering phase.

iOS Build Memory Access Issues Causing Crashes
Our app has an old codebase, originating in 2011, which started out as purely Objective-C (and a little bit of Objective-C++), but a good amount of Swift has been added over time as well. Lots of Objective-C and Swift inter-op, but in general very few 3rd party libraries/frameworks. Like many other codebases of this size and age, we have a good amount of accumulated tech debt. In our case, that mostly comes in the form of using old/deprecated APIs (OpenGL primary amongst them), and also using some ‘tricks’ that allowed us to do highly customized UI popups and the like before they were officially supported by iOS, but unfortunately are still in use to this day (i.e. adding views directly to the UIWindow such that that are ‘on top’ of everything, instead of presenting a VC). Overall though, the app is very powerful and capable, and generally has a relatively low crash rate. About two months ago, we started seeing some new crashes that seemed to be totally unrelated to the code changes that were made at the time. Moreover, if a new branch with a feature or bug fix was merged in, the new crash would either disappear entirely, or move somewhere else. These were not ‘normal’ crashes either - when hooked up to the debugger in Xcode, often times the crashes would happen when calling into system library (e.g. initializing a UIColor object). Some of the steps taken to try and mitigate or eliminate these crashes include: Rolling back merges Often worked, but then most future merges would cause a new and different crash to appear Using the TSan and ASan tools to try and diagnose thread or memory issues TSan reported a couple of issues near launch that have been fixed, and there are others in some areas of the app, but they have been around a long time and don’t appear to correlate with any recent changes, nor did fixing the ones at launch (and throughout testing to try and reproduce crashes) result in elimination of the new crashes ASan does not identify any issues Modifying the code changes in a branch before merging it in In one case where the changes were limited to declaring ‘@objc static var: Bool’ in a Swift class and setting a value to it in a couple of places, simply removing the @objc from the declaration would result in the crash going away. Since the var had to be exposed to Objective-C, it was eventually moved to a pure Objective-C class that already existed and is a singleton (not ideal, but it’s been around a long time and has not yet been refactored) in order to preserve the functionality and the crash was no longer reproducible Removing all 3rd party libraries or frameworks Not a long-term solution, and this mostly worked in that the crashes went away, but it also resulted in removal of long-existing features expected by our users Updating 3rd party libraries and frameworks when possible (there were some very old ones) Updating these did not have any effect on the crashes, except that the crashes moved around in the same way as when merging in a branch, and again, where the crash actually occurred was uncorrelated with the library/framework that was updated Changes to the App’s Build Settings in Xcode Set supported/valid architectures to arm64 exclusively Stripping of all architectures other than arm64 from 3rd party binaries Cleaning up of old/outdated linker flags Removal of other custom build flags that were needed at one point, but are no longer relevant Generally trying to make all the build settings in our (quite old/outdated) app match those of a newly created iOS app Code signing inject base entitlements is set to YES Removal of old/deprecated BitCode flag These changes seemed to help and the codebase was more ‘stable’ (non-crashing) for a while, but as we tried to continue development, the crashes would reappear Getting crash reports off of test devices and analyzing them based on the various documents about crash reports provided by Apple This was helpful and pointed to new things to investigate, but ultimately did not help to identify the root cause of these crashes Throughout all of the above, the crashes would come and go, very reproducibly for a given branch being merged in, but if a subsequent branch is merged in, the crash may go away, or simply move somewhere else - sometimes it would crash in our code that calls other parts of our code, and other times when calling system frameworks (like the UIColor example above). One thing that is consistent though, is that the crash would never happen anywhere near the code that was changed or added by a branch that was merged in. Additional observations when trying to figure out the cause of these crashes: Sometimes the smallest code change would result in a crash happening or not The crash reports generated on-device vary quite a bit in terms of the type and reason for the crash All crashes have an Exception Type of EXC_BAD_ACCESS, but vary between (SIGABRT) (SIGBUS) (SIGKILL) (SIGSEV) The crashing thread is often (but not always) on Thread 0 (main thread), and often the first line in the backtrace would be just ‘???’, sometimes followed by a valid memory address and file, but often times just ‘0x0 ???’ Most crash reports have an exception subtype of KERN_PROTECTION_FAILURE Many also state that the Termination Reason is ‘CODESIGNING 2 Invalid Page’ This in particular was investigated thoroughly, including looking at the Placing Content In A Bundle document but after further changes to ensure that everything is in the right place, the crashes were still observed Another odd thing in most of the crash reports is in the Binary Images section, there is a line that once again is mostly ???s or 000s - specifically ‘0x0 - 0xffffffffffffffff ??? unknown-arch <00000000000000000000000000000000> ???’ The crashes occur on different physical devices, typically the same crash for a given branch, and regardless of iOS version This includes building from different Macs. We did observe some differences between versions of Xcode (crashed similarly when built from an older version of Xcode, but not from a newer one), but we recently had all developers ensure they are running Xcode 16.4 - we also tried Xcode 26, but the crashes were still observed Overall, it seems like there is something very strange going on in terms of how the App binary is constructed such that a small code change somehow affects the binary in such a way that memory is not being accessed correctly, or is not where it is expected to be. This level of what appears to be a build-time issue that manifests in very strange run-time crashes is both confusing and difficult to diagnose. Despite the resources provided by Apple for investigation and diagnosis, we cannot seem to find a root cause for these crashes and eliminate them for good.

Why does a Swift test think my simple struct is main actor-isolated?
My experience with Swift 6 strict concurrency so far doesn't match my understanding of implicit MainActor isolation semantics. This is a cross-post from StackOverflow. I will link answers between both forums. TL;DR Build succeeds when testing a struct declared in the test module, but fails when the struct is moved to the main module: Main actor-isolated property … cannot be accessed from outside the actor. Steps to reproduce Open up Xcode 26 beta 2 on macOS 26 (probably also ok on current stables). Create a new Swift app with Swift testing, no storage. Call it WhatTheSwift. Set the Swift Language Version on all three targets to Swift 6. Update the default test file to be this: import Testing @testable import WhatTheSwift struct WhatTheSwiftTests { @Test func example() async throws { let thing = Thing(foo: "bar") #expect(thing.foo == "bar") } } struct Thing { let foo: String } That should build fine, and the tests should pass. Now, move the Thing declaration into its own Thing.swift file in the WhatTheSwift module, and try running the test again. You should see this: Observations Marking the test @MainActor allows the test to pass, suggesting the compiler actually wants to isolate Thing.foo to the main actor. My question Why? And why only when Thing is in a different module?

Capacitor iOS Plugin with MobileVLCKit – Swift Plugin Not Recognized from Angular
Hi everyone, I'm developing a Capacitor plugin to display an RTSP video stream using MobileVLCKit on iOS. The Android side works perfectly, but I can’t get the iOS plugin to work — it seems my Swift file is not being detected or recognized, even though I’ve followed the official steps. What works: I followed the Capacitor Plugin Development Guide. I implemented the Android version of the plugin in Java inside the android/ folder. Everything works perfectly from Angular: the plugin is recognized and calls execute correctly. The issue on iOS: I implemented the iOS part in Swift, using the official MobileVLCKit documentation. I initially placed my RtspVlcPlugin.swift file in the plugin’s iOS folder, as the docs suggest. Then I moved it directly into the main app’s ios/App/App/ folder next to AppDelegate.swift and tried manual registration. The problem: Even though I manually register the plugin with: if let bridge = self.window?.rootViewController as? CAPBridgeViewController { bridge.bridge?.registerPluginInstance(RtspVlcPlugin()) print("✅ Plugin RtspVlcPlugin registered manually.") } It prints the registration message just fine. BUT from Angular, the plugin is not recognized: Capacitor.Plugins.RtspVlcPlugin has no methods, and I get this error: "code":"UNIMPLEMENTED" I also tried declaring @objc(RtspVlcPlugin) and extending CAPPlugin. I’ve verified RtspVlcPlugin.swift is added to the target and compiled. The Swift file doesn’t seem to register or expose any methods to Angular. I even tried adding the code without using a plugin at all — just creating a Swift class and using it via the AppDelegate, but it still doesn't expose any callable methods. My Swift code (RtspVlcPlugin.swift): import Capacitor import MobileVLCKit @objc(RtspVlcPlugin) public class RtspVlcPlugin: CAPPlugin, VLCMediaPlayerDelegate { var mediaPlayer: VLCMediaPlayer? var containerView: UIView? var spinner: UIActivityIndicatorView? @objc func iniciar(_ call: CAPPluginCall) { guard let urlStr = call.getString("url"), let x = call.getDouble("x"), let y = call.getDouble("y"), let w = call.getDouble("width"), let h = call.getDouble("height"), let url = URL(string: urlStr) else { call.reject("Missing parameters") return } DispatchQueue.main.async { self.containerView?.removeFromSuperview() let cont = UIView(frame: CGRect(x: x, y: y, width: w, height: h)) cont.backgroundColor = .black cont.layer.cornerRadius = 16 cont.clipsToBounds = true let sp = UIActivityIndicatorView(style: .large) sp.center = CGPoint(x: w/2, y: h/2) sp.color = .white sp.startAnimating() cont.addSubview(sp) self.spinner = sp self.containerView = cont self.bridge?.viewController?.view.addSubview(cont) let player = VLCMediaPlayer() player.delegate = self player.drawable = cont player.media = VLCMedia(url: url) self.mediaPlayer = player player.play() call.resolve() } } @objc func cerrar(_ call: CAPPluginCall) { DispatchQueue.main.async { self.mediaPlayer?.stop() self.mediaPlayer = nil self.spinner?.stopAnimating() self.spinner?.removeFromSuperview() self.spinner = nil self.containerView?.removeFromSuperview() self.containerView = nil call.resolve() } } public func mediaPlayerStateChanged(_ aNotification: Notification!) { guard let player = mediaPlayer, player.state == .playing, let sp = spinner else { return } DispatchQueue.main.async { sp.stopAnimating() sp.removeFromSuperview() self.spinner = nil } } } In the Angular project, I’m using the plugin by manually registering it with registerPlugin from @capacitor/core. Specifically, in the service where I need it, I do the following: import { registerPlugin } from '@capacitor/core'; const RtspVlcPlugin: any = registerPlugin('RtspVlcPlugin'); After this, I try to call the methods defined in the iOS plugin, like RtspVlcPlugin.iniciar({ ... }), but I get an UNIMPLEMENTED error, which suggests that the plugin is not exposing its methods properly to the Angular/Capacitor environment. That makes me believe the problem lies in how the Swift file is integrated or registered, rather than how it is used from Angular. I’d appreciate any guidance on how to properly expose a Swift-based Capacitor plugin’s methods so that they are accessible from Angular. Is there any additional registration step or metadata I might be missing on the iOS side?

How to call a Swift file directly from Angular using Capacitor?
Hi everyone, I’m working on a Capacitor app built with Angular, and I’m trying to call a Swift class directly from the root of the iOS project (next to AppDelegate.swift) without using a full Capacitor plugin structure. The Swift file is called RtspVlcPlugin.swift and looks like this: import Capacitor @objc(RtspVlcPlugin) public class RtspVlcPlugin: CAPPlugin { @objc func iniciar(_ call: CAPPluginCall) { call.resolve() } } In AppDelegate.swift I register it like this: if let bridge = self.window?.rootViewController as? CAPBridgeViewController { bridge.bridge?.registerPluginInstance(RtspVlcPlugin()) print("✅ RtspVlcPlugin registered.") } The registration message prints correctly in Xcode logs. But from Angular, when I try to call it like this: import { registerPlugin } from '@capacitor/core'; const RtspVlcPlugin: any = registerPlugin('RtspVlcPlugin'); RtspVlcPlugin.iniciar({ ... }); I get this error: {"code":"UNIMPLEMENTED"} So, even though the plugin is registered manually, it’s not exposing any methods to the Angular/Capacitor runtime. My question is: What is the correct way to access a manually created Swift class (in the root of the iOS project) from Angular via Capacitor? Thanks in advance!

Unexpected timezone issues
Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this: "days": [ { "forecastStart": "2025-06-25T00:00:00Z", "forecastEnd": "2025-06-26T00:00:00Z", "daytimeForecast": { "forecastStart": "2025-06-25T07:00:00Z", "forecastEnd": "2025-06-25T19:00:00Z", "overnightForecast": { "forecastStart": "2025-06-25T19:00:00Z", "forecastEnd": "2025-06-26T07:00:00Z",} It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same. The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local. However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised. I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other. Can anyone help me understand what's happening here? And furthermore in the example above, the 24 hour forecasts that have, for example this: "forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

LibGDX/MobiVM App refuses to launch on iOS 26.0.1
Hello, currently I am having trouble releasing an app because it crashes/does not launch on iOS 26.0.1. We have uploaded apps in the past so I tried building one of them with our current toolchain. I use Xcode 16.4, Kotlin version 2.0.0, LibGDX 1.13.1 and robovm/MobiVM 2.3.23. I uploaded the build to TestFlight and tested with physical devices running iOS 18.5 and 26.0.1. It runs fine on 18.5 but refuses to launch on the 26.0.1 device. I cannot retrieve a crash log or .ips file because none is written. When I write a Console log while the app crashes/does not launch I get no hints as to why it does so. Do you maybe have additional ideas as to why it keeps not launching on iOS 26.0.1?

Embed/Do Not Embed & Mach-O type
My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

Unexpected app version in logs — does MARKETING_VERSION change dynamically?
Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? yaml: info.plist:

Include the release date and sw_vers in macos release notes
This is not exactly a feedback about the forums but I couldn't find a better location to ask this question. The macos release notes are hosted at developer.apple.com. For example, the macos 26.4 release note is here https://developer.apple.com/documentation/macos-release-notes/macos-26_4-release-notes. Would it be possible to include the release date in those release notes? Right now, it's hard to locate that information. It would also be useful to even include the sw_vers of that particular release in those release notes. For example: ProductName: macOS ProductVersion: 26.4 BuildVersion: 25E246 Having the sw_vers and the release date in the first few lines of the release note would be handy. The reason I went looking for the release date was because the corresponding sources for macos 26.4 hasn't yet been listed at https://opensource.apple.com/releases/. It usually takes a few days for that to happen, so I wanted to see how long it has been since 26.4 was released.

Feedback Assistant: „This Feedback will no longer be monitored, and incoming messages will not be reviewed.“
Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

Use of non-public or deprecated APIs
Hello, "This issue is blocking App store approval" I have tried pushing my application to Appstore. However it has been rejected on the following ground: _"As we discussed, the app uses or references the following non-public or deprecated APIs: Frameworks/CommonLibrary.framework/CommonLibrary Symbols: • _SecCertificateIsValid The use of non-public or deprecated APIs is not permitted, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms."_ I have scanned the app using "strings" tool & "otool -ov" tool. But they have come out clean. No Non-public or deprecated APIs detected. Please advise which tool can be used to scan the CL to locate where the deprecated API or non-public API lies and also how to rectify the same. Thanks Saikat Bakshi.

Fake JournalingSuggestions for testing?
I want to test different types of journaling suggestions, like for example photo/video containing ones but as a developer I have no control over what's shown in the Journaling Suggestions sheet. And this makes it really difficult to develop or test any suggestion type other than "reflection". Please let us have a fake suggestions sheet that includes all kinds of suggestion types so we can test. We could toggle it under Developer settings I think.

Additional observations when trying to figure out the cause of these crashes: Sometimes the smallest code change would result in a crash happening or not The crash reports generated on-device vary quite a bit in terms of the type and reason for the crash All crashes have an Exception Type of EXC_BAD_ACCESS, but vary between (SIGABRT) (SIGBUS) (SIGKILL) (SIGSEV) The crashing thread is often (but not always) on Thread 0 (main thread), and often the first line in the backtrace would be just ‘???’, sometimes followed by a valid memory address and file, but often times just ‘0x0 ???’ Most crash reports have an exception subtype of KERN_PROTECTION_FAILURE Many also state that the Termination Reason is ‘CODESIGNING 2 Invalid Page’ This in particular was investigated thoroughly, including looking at the Placing Content In A Bundle document but after further changes to ensure that everything is in the right place, the crashes were still observed Another odd thing in most of the crash reports is in the Binary Images section, there is a line that once again is mostly ???s or 000s - specifically ‘0x0 - 0xffffffffffffffff ??? unknown-arch <00000000000000000000000000000000> ???’ The crashes occur on different physical devices, typically the same crash for a given branch, and regardless of iOS version This includes building from different Macs. We did observe some differences between versions of Xcode (crashed similarly when built from an older version of Xcode, but not from a newer one), but we recently had all developers ensure they are running Xcode 16.4 - we also tried Xcode 26, but the crashes were still observed Overall, it seems like there is something very strange going on in terms of how the App binary is constructed such that a small code change somehow affects the binary in such a way that memory is not being accessed correctly, or is not where it is expected to be. This level of what appears to be a build-time issue that manifests in very strange run-time crashes is both confusing and difficult to diagnose. Despite the resources provided by Apple for investigation and diagnosis, we cannot seem to find a root cause for these crashes and eliminate them for good.

Why does a Swift test think my simple struct is main actor-isolated?
My experience with Swift 6 strict concurrency so far doesn't match my understanding of implicit MainActor isolation semantics. This is a cross-post from StackOverflow. I will link answers between both forums. TL;DR Build succeeds when testing a struct declared in the test module, but fails when the struct is moved to the main module: Main actor-isolated property … cannot be accessed from outside the actor. Steps to reproduce Open up Xcode 26 beta 2 on macOS 26 (probably also ok on current stables). Create a new Swift app with Swift testing, no storage. Call it WhatTheSwift. Set the Swift Language Version on all three targets to Swift 6. Update the default test file to be this: import Testing @testable import WhatTheSwift struct WhatTheSwiftTests { @Test func example() async throws { let thing = Thing(foo: "bar") #expect(thing.foo == "bar") } } struct Thing { let foo: String } That should build fine, and the tests should pass. Now, move the Thing declaration into its own Thing.swift file in the WhatTheSwift module, and try running the test again. You should see this: Observations Marking the test @MainActor allows the test to pass, suggesting the compiler actually wants to isolate Thing.foo to the main actor. My question Why? And why only when Thing is in a different module?

Capacitor iOS Plugin with MobileVLCKit – Swift Plugin Not Recognized from Angular
Hi everyone, I'm developing a Capacitor plugin to display an RTSP video stream using MobileVLCKit on iOS. The Android side works perfectly, but I can’t get the iOS plugin to work — it seems my Swift file is not being detected or recognized, even though I’ve followed the official steps. What works: I followed the Capacitor Plugin Development Guide. I implemented the Android version of the plugin in Java inside the android/ folder. Everything works perfectly from Angular: the plugin is recognized and calls execute correctly. The issue on iOS: I implemented the iOS part in Swift, using the official MobileVLCKit documentation. I initially placed my RtspVlcPlugin.swift file in the plugin’s iOS folder, as the docs suggest. Then I moved it directly into the main app’s ios/App/App/ folder next to AppDelegate.swift and tried manual registration. The problem: Even though I manually register the plugin with: if let bridge = self.window?.rootViewController as? CAPBridgeViewController { bridge.bridge?.registerPluginInstance(RtspVlcPlugin()) print("✅ Plugin RtspVlcPlugin registered manually.") } It prints the registration message just fine. BUT from Angular, the plugin is not recognized: Capacitor.Plugins.RtspVlcPlugin has no methods, and I get this error: "code":"UNIMPLEMENTED" I also tried declaring @objc(RtspVlcPlugin) and extending CAPPlugin. I’ve verified RtspVlcPlugin.swift is added to the target and compiled. The Swift file doesn’t seem to register or expose any methods to Angular. I even tried adding the code without using a plugin at all — just creating a Swift class and using it via the AppDelegate, but it still doesn't expose any callable methods. My Swift code (RtspVlcPlugin.swift): import Capacitor import MobileVLCKit @objc(RtspVlcPlugin) public class RtspVlcPlugin: CAPPlugin, VLCMediaPlayerDelegate { var mediaPlayer: VLCMediaPlayer? var containerView: UIView? var spinner: UIActivityIndicatorView? @objc func iniciar(_ call: CAPPluginCall) { guard let urlStr = call.getString("url"), let x = call.getDouble("x"), let y = call.getDouble("y"), let w = call.getDouble("width"), let h = call.getDouble("height"), let url = URL(string: urlStr) else { call.reject("Missing parameters") return } DispatchQueue.main.async { self.containerView?.removeFromSuperview() let cont = UIView(frame: CGRect(x: x, y: y, width: w, height: h)) cont.backgroundColor = .black cont.layer.cornerRadius = 16 cont.clipsToBounds = true let sp = UIActivityIndicatorView(style: .large) sp.center = CGPoint(x: w/2, y: h/2) sp.color = .white sp.startAnimating() cont.addSubview(sp) self.spinner = sp self.containerView = cont self.bridge?.viewController?.view.addSubview(cont) let player = VLCMediaPlayer() player.delegate = self player.drawable = cont player.media = VLCMedia(url: url) self.mediaPlayer = player player.play() call.resolve() } } @objc func cerrar(_ call: CAPPluginCall) { DispatchQueue.main.async { self.mediaPlayer?.stop() self.mediaPlayer = nil self.spinner?.stopAnimating() self.spinner?.removeFromSuperview() self.spinner = nil self.containerView?.removeFromSuperview() self.containerView = nil call.resolve() } } public func mediaPlayerStateChanged(_ aNotification: Notification!) { guard let player = mediaPlayer, player.state == .playing, let sp = spinner else { return } DispatchQueue.main.async { sp.stopAnimating() sp.removeFromSuperview() self.spinner = nil } } } In the Angular project, I’m using the plugin by manually registering it with registerPlugin from @capacitor/core. Specifically, in the service where I need it, I do the following: import { registerPlugin } from '@capacitor/core'; const RtspVlcPlugin: any = registerPlugin('RtspVlcPlugin'); After this, I try to call the methods defined in the iOS plugin, like RtspVlcPlugin.iniciar({ ... }), but I get an UNIMPLEMENTED error, which suggests that the plugin is not exposing its methods properly to the Angular/Capacitor environment. That makes me believe the problem lies in how the Swift file is integrated or registered, rather than how it is used from Angular. I’d appreciate any guidance on how to properly expose a Swift-based Capacitor plugin’s methods so that they are accessible from Angular. Is there any additional registration step or metadata I might be missing on the iOS side?

How to call a Swift file directly from Angular using Capacitor?
Hi everyone, I’m working on a Capacitor app built with Angular, and I’m trying to call a Swift class directly from the root of the iOS project (next to AppDelegate.swift) without using a full Capacitor plugin structure. The Swift file is called RtspVlcPlugin.swift and looks like this: import Capacitor @objc(RtspVlcPlugin) public class RtspVlcPlugin: CAPPlugin { @objc func iniciar(_ call: CAPPluginCall) { call.resolve() } } In AppDelegate.swift I register it like this: if let bridge = self.window?.rootViewController as? CAPBridgeViewController { bridge.bridge?.registerPluginInstance(RtspVlcPlugin()) print("✅ RtspVlcPlugin registered.") } The registration message prints correctly in Xcode logs. But from Angular, when I try to call it like this: import { registerPlugin } from '@capacitor/core'; const RtspVlcPlugin: any = registerPlugin('RtspVlcPlugin'); RtspVlcPlugin.iniciar({ ... }); I get this error: {"code":"UNIMPLEMENTED"} So, even though the plugin is registered manually, it’s not exposing any methods to the Angular/Capacitor runtime. My question is: What is the correct way to access a manually created Swift class (in the root of the iOS project) from Angular via Capacitor? Thanks in advance!

Unexpected timezone issues
Hi, my server in Melbourne Australia is getting weather forecasts from a few places around Australia. When I look at the daily timesteps that I get back, they might be something like this: "days": [ { "forecastStart": "2025-06-25T00:00:00Z", "forecastEnd": "2025-06-26T00:00:00Z", "daytimeForecast": { "forecastStart": "2025-06-25T07:00:00Z", "forecastEnd": "2025-06-25T19:00:00Z", "overnightForecast": { "forecastStart": "2025-06-25T19:00:00Z", "forecastEnd": "2025-06-26T07:00:00Z",} It doesn't matter where I ask for - Melbourne, Darwin, Perth, it always comes back the same. The documentation says that daytimeForecast is 7 am to 7 pm local and overnightForecast is 7pm to 7 am local. However, in a place like Perth 7-19Z is 3 pm to 3 am, not 7 pm to 7 am like advertised. I can see that for any given date, there are 3 maximum temperature forecasts, a 24 hour max, a daytime max and an overnight max and they differ from each other. Can anyone help me understand what's happening here? And furthermore in the example above, the 24 hour forecasts that have, for example this: "forecastStart": "2025-06-25T00:00:00Z" ... Can the 00:00:00Z be trusted literally? Or is it more the case that it's "2025-06-25" but the HMS got tacked on in a conversion?

LibGDX/MobiVM App refuses to launch on iOS 26.0.1
Hello, currently I am having trouble releasing an app because it crashes/does not launch on iOS 26.0.1. We have uploaded apps in the past so I tried building one of them with our current toolchain. I use Xcode 16.4, Kotlin version 2.0.0, LibGDX 1.13.1 and robovm/MobiVM 2.3.23. I uploaded the build to TestFlight and tested with physical devices running iOS 18.5 and 26.0.1. It runs fine on 18.5 but refuses to launch on the 26.0.1 device. I cannot retrieve a crash log or .ips file because none is written. When I write a Console log while the app crashes/does not launch I get no hints as to why it does so. Do you maybe have additional ideas as to why it keeps not launching on iOS 26.0.1?

Embed/Do Not Embed & Mach-O type
My Xcode project has the following configuration: 1 iOS app target 1 Xcode framework target (mach-o-type "Dynamic Library") 5 static libraries Dependencies: All the static libraries are target dependencies of the framework. The framework is the only target dependency of the iOS app. For the iOS app target, within the General tab > Frameworks, Libraries & Embedded content, I've set the framework as "Do not embed" So now I have a dynamic framework which won't be copied to the .app bundle in the build output. As per my understanding, this should result in a runtime error, dyld should not be able to find the framework files as they were not embedded in the final .app bundle. But regardless, my app runs without any errors, using all the methods exposed by the framework. What is the correct understanding here? What exactly does Embed/Do not embed mean (apart from excluding the files from .app bundle) When both settings are specified, is there any priority or precedence of one setting over the other?

Unexpected app version in logs — does MARKETING_VERSION change dynamically?
Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? yaml: info.plist:

Include the release date and sw_vers in macos release notes
This is not exactly a feedback about the forums but I couldn't find a better location to ask this question. The macos release notes are hosted at developer.apple.com. For example, the macos 26.4 release note is here https://developer.apple.com/documentation/macos-release-notes/macos-26_4-release-notes. Would it be possible to include the release date in those release notes? Right now, it's hard to locate that information. It would also be useful to even include the sw_vers of that particular release in those release notes. For example: ProductName: macOS ProductVersion: 26.4 BuildVersion: 25E246 Having the sw_vers and the release date in the first few lines of the release note would be handy. The reason I went looking for the release date was because the corresponding sources for macos 26.4 hasn't yet been listed at https://opensource.apple.com/releases/. It usually takes a few days for that to happen, so I wanted to see how long it has been since 26.4 was released.

Feedback Assistant: „This Feedback will no longer be monitored, and incoming messages will not be reviewed.“
Every now and then I get this very frustrating message on Feedback Assistant. For instance, in FB14696726 I reported an issue with the App Store Connect API. 4 weeks later, I got a reply, asking among other things for a „correlation key and Charles log“. I immediately replied saying that I didn‘t know what those are, and they replied After reviewing your feedback, it is unclear what the exact issue is. I pointed out that I had asked a question which was left unanswered, and they replied explaining what the correlation key is. Then I asked again what the Charles log is. They replied The Apple Developer website provides access to a range of videos covering various topics on using and developing with Apple technologies. You can find these videos on our Development Videos page: http://developer.apple.com/videos. I opened the link and searched for „Charles“ but there were no results, so I asked to kindly point me to the video answering my question. They replied 3 months later (today): Following up on our last message, we believe this issue is either resolved or not reproducible with the information provided and will now consider this report closed internally. This Feedback will no longer be monitored, and incoming messages will not be reviewed. This is not the first time I ask for clarification and get back a message basically telling me that „we won‘t answer any questions you may have and won‘t hear anything you still may have to say about this issue“. They didn‘t even ask me to verify if the issue is resolved or not, like they sometimes do. No, they just shut the door in my face. I just wanted to share this frustrating experience. Perhaps an Apple engineer wants to say something about it or a developer has had a similar experience?

Use of non-public or deprecated APIs
Hello, "This issue is blocking App store approval" I have tried pushing my application to Appstore. However it has been rejected on the following ground: _"As we discussed, the app uses or references the following non-public or deprecated APIs: Frameworks/CommonLibrary.framework/CommonLibrary Symbols: • _SecCertificateIsValid The use of non-public or deprecated APIs is not permitted, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms."_ I have scanned the app using "strings" tool & "otool -ov" tool. But they have come out clean. No Non-public or deprecated APIs detected. Please advise which tool can be used to scan the CL to locate where the deprecated API or non-public API lies and also how to rectify the same. Thanks Saikat Bakshi.

Fake JournalingSuggestions for testing?
I want to test different types of journaling suggestions, like for example photo/video containing ones but as a developer I have no control over what's shown in the Journaling Suggestions sheet. And this makes it really difficult to develop or test any suggestion type other than "reflection". Please let us have a fake suggestions sheet that includes all kinds of suggestion types so we can test. We could toggle it under Developer settings I think.

Can the bundle ID for an unsubmitted app be reused?
I was developing an app using a certain bundle ID, but then had to delete it (and I also removed the app ID Identifier) My question is, can I make a new app with the exact same bundle ID as I was using on the removed one?
