Hi there, I'm having an app developed in the last weeks, and recently I'm testing it on iOS 18. This following piece of UI code has diff between iOS 18 and iOS version lower than 18. I have a NavigationStack in my homeView, and the display difference is for its toolbar in one destination. I've tried both approaches in code, with header variable or ToolbarItemGroup used directly in the toolbar modifier, both would result in there being a spacer between the body VStack and toolbar, which is unexpected. Here's the code and a demo screenshot. var body: some View { // header VStack(alignment: .leading) { notificationView( iconKey: "ErrorCircle", contentKey: "receivedFile.notification.noNetwork.content" ) fileListView } .toolbar { // header ToolbarItemGroup(placement: .principal) { Button { dismiss() } label: { Image(systemName: "chevron.backward") } .background(Color.yellow) Spacer() Text(LocalizedStringKey("title")) .font( .system(size: 17) .weight(.semibold) ) .background(Color.yellow) Spacer() Button { print("click") } label: { Text("Click") } .background(Color.yellow) } } .navigationBarBackButtonHidden() .onAppear { refreshAllFiles() } } @ToolbarContentBuilder private var header: some ToolbarContent { ToolbarItem(placement: .topBarLeading) { Button { dismiss() } label: { Image(systemName: "chevron.backward") } .background(Color.yellow) } ToolbarItem(placement: .principal) { Text(LocalizedStringKey("receivedFileList.title")) .font( .system(size: 17) .weight(.semibold) ) .background(Color.yellow) } ToolbarItem(placement: .topBarTrailing) { Button { print("click for jumping") } label: { Text("Click for jumping") } .background(Color.yellow) } } Hope I can get some help from the forum on the usage. If not fixable, may I know if this is a known issue that would be fixed in the next upgrades.

Hi, I am trying to get login with my Apple ID to download new software but it’s not taking. Does anyone knows what should I do?

I have an iOS and watchOS app where both can run independently, I am not using WatchConnectivity to send data back and fourth. The issue I'm having is that if I schedule a local notification on the watch and the phone is unlocked, it will not show on the watch for about 10-15 seconds. If I uninstall the iOS app or have the phone locked, it will show immediately on the watch. To my understanding, this is somewhat the expected functionality but is there a way to bypass it? My app is a timer app and it really should not have a delay.

Hello, I am planning to create an app that can transfer files to hardware devices via WiFi. With devices like GoPro, I believe the typical setup involves the GoPro creating a WiFi hotspot to which the iOS app connects, allowing file transfers. But this setup establishes a 1:1 connection between the app and the hardware. To support multiple hardware devices simultaneously, I am considering reversing this setup: the iOS device would create a personal hotspot, and the hardware devices would connect to it. However, I have concerns about this approach: Reliability: I have read that the personal hotspot feature on iOS devices can be unreliable, especially with non-Apple devices, which tend to disconnect frequently. Manual Setup: There is no API to programmatically create the personal hotspot, so users would have to enable it manually in the Settings. I can use isIdleTimerDisabled to prevent the iOS screen from going to sleep, which might help with disconnection issues. Aside from this, are there other things I can do to ensure a stable connection? Given my limited experience with hardware connections, I am uncertain if having the iOS device act as the WiFi access point is a good design. Any advice or alternative solutions would be greatly appreciated. Thank you in advance!

We are trying to upload iOS app in Test Flight. The iOS SDK version we are using is 18 and Xcode Version is 16. While uploading the app (we are using Jenkins & Fastlane), we are getting an error saying the app is built with iOS SDK 16.4. Due to that we the upload is failing. The error text says An error occurred during the build: Error uploading ipa file: [Application Loader Error Output]: [ContentDelivery.UploadError c0000171810C] Asset validation failed (90725) SDK version issue.

Hello, I'm currently facing some issues with localization for the Safari extension on iOS: Issues with Language Tags: Folder names like pt-BR (Brazilian Portuguese) and pt-PT (European Portuguese) placed in the Resources/_locales/ directory are not displaying the respective languages correctly; instead, the default English is shown. Similarly, using folder names like zh-CN (Simplified Chinese) and zh-TW (Traditional Chinese) also results in default English display instead of the intended Chinese language. Conversely, when changing the folder names to pt (Portuguese general) and zh (Chinese general), the languages display correctly. Could you please provide any recommendations or tips regarding language tag settings and how to ensure they are properly recognized according to RFC 5646? Thanks for your help! Best,

My application suddenly started crashing on launch when I target "My Mac - designed for iPad." But only after the first build from scratch, which runs once. All subsequent runs crash with: dyld[90869]: Symbol not found: _OBJC_CLASS_$_AVPlayerView Referenced from: <D566512D-CAB4-3EA6-9B87-DBD15C6E71B3> /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Debugger/libViewDebuggerSupport.dylib Expected in: <4C34313C-03AD-32EB-8722-8A77C64AB959> /System/iOSSupport/System/Library/Frameworks/AVKit.framework/Versions/A/AVKit I don't use AVPlayerView anywhere in my application. A file-contents search of the entire source tree doesn't turn it up either. The application doesn't even get to the point of instantiating the app object, so none of my code is involved. If I switch the target to my iPhone, it will build and run repeatedly. If I then switch back to "My Mac," it will build and run once... and then crash every time. Further research shows that this only happens in Debug builds. This is a major issue right now because iOS 18 broke authentication certificates (thus HTTPS), so anyone writing or debugging an app that needs network functionality must use HTTP on localhost. In my case, I'm dead in the water because I can't debug on my local machine. Has anyone seen something like this before? I can find no reference to anything like it.

I am trying to build my app with Xcode16 on iOS18, once app is going background PIP is enable but whenever app is coming back to foreground by tapping on PIP, black screen appears(video is playing in background). It only happening with build created by Xcode16 and running on iOS18. It working fine with build created by Xcode15.4. My first thought on it that somehow PIP is not stoping.

With this sample code here: import SwiftUI struct ContentView: View { var body: some View { Text("Hello world") .hoverEffect(isEnabled: true) } } private extension View { func hoverEffect(isEnabled: Bool) -> some View { if #available(iOS 17.0, *) { // VisionOS 2.0 goes in here? return self .hoverEffect(.automatic, isEnabled: isEnabled) } else { return self } } } You would expect if the destination was visionOS it would go into the else block but it doesn't. That seems incorrect since the condition should be true if the platform is iOS 17.0+. Also, I had this similar code that was distriubted via a xcframework and when that view is used in an app that is using the xcframework while running against visionOS there would be a runtime crash (EXC_BAD_ACCESS). The crash could only be reproduced when using that view from the xcframework and not the local source code. The problem was fixed by adding visionOS 1.0 to that availability check. But this shouldn't have been a crash in the first place. Does anyone have thoughts on this or possibly an explanation? Thank you!

I was trying to debug an issue with entry point not being found on iOS 18.0 simulator and device(iPhone 14 Pro) with no success since the Xcode console output just prints No entry point found. Checked '(null)'. Later when I tried to use iOS 15.0 Simulator of iPhone 13 to see if it makes a difference, I could see more verbose messages from the loader trying to look for entry points and was able to pin point the root cause of the issue. Nothing was changed in the project settings, env variables or anything except switching to iOS 15.0 simulator from iOS 18.0 simulator, so I don't think it is environment issue or project configuration issue. The absence of detailed logging got me stuck on this issue for sometime. The same issue (minimal logging) was observed on iOS 17.4 simulator as well but is not present on iOS 15.0. iOS 18.0 Log: No entry point found.

Hello, Is there a way to retrieve the dark mode and the tinted app icons using personal iOS device, or alternatively through an available API? I wasn't able to find anything online or on the existing form posts. I tried using: xcrun devicectl device info appIcon But this command only returns a light mode icon for an app and I didn't see any options/flags for dark mode or tinted icons Software Version info: XCode - 16 MacOS 15.1 Beta (24B5070a) devicectl - 397.21 xcrun - version 70, platform version 15.0 Let me know if any other info would be helpful. Thanks!

I’m a bit confused about the practicality and support for Umbrella frameworks in iOS. I’ve read that they’re not supported, but I’ve come across a few tutorials where people are developing Umbrella frameworks. Can anyone provide some insight on this?

I have enabled Developer mode on the iPhone and paired my device. I see it as an option on Xcode, but I am unable to run any simulations on my device. When I go into Settings->General->VPN & Device Management, I only see an option for VPN, not for my Mac. What do I need to do to be able to run my app on my iPhone? Thank you

I’m unable to install iOS 18.1 on my device , the update not show up on the developer beta update, how can I fix . i already installed ios 18, I have over 200 GB of space and I have an iPhone 15 pro max .

Incremental builds using xcodebuild are very slow, around 3x slower when compared to the same build using Xcode. Recently, I discovered that CODE_SIGNING_ALLOWED=NO" fixed the issue, but of course, I can't then run iOS app. It seems like automatic signing using xcodebuild is somehow broken. Therefore, I think I could set CODE_SIGNING_ALLOWED=NO" and sign it manually later. However, I'm not sure how to do that. I checked what Xcode does and it's: /usr/bin/codesign --force --sign - --entitlements /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Intermediates.noindex/XYZ.build/Debug-iphonesimulator/XYZ.build/XYZ.app.xcent --timestamp\=none --generate-entitlement-der /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app However, if I run xcodebuild with disabled signing I don't have XYZ.app.xcent required by this command. I also tried: codesign --force --deep --sign "Apple Development: John Snow (XYZ)" /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app but the app immediately terminates (the same way like when unsigned). Could anyone help with that?

I frequently use my iPad to develop remotely in VSCode or prototype designs in Figma. This is currently all done in the browser. Given that many of these experiences rely heavily on the keyboard I was hoping there would be a solution to make a keyboard persistent on the screen, or at least a few hot keys. Is it possible for me to develop an accessibility tool that could stay persistent on the screen? Perhaps something that would talk with assistive touch? Or is that in Apple’s no no square?

I have a website that uses tables for listing our certifications. A customer is complaining that on their browser, the contents of the tables are being viewed upside down. They should be showing vertically. This is not happening on any other browser that I have tested. Has anyone had this issue and what did you do to fix it. https://www.mccampbell.com/statement.php Thank you for your help. Much appreciated. Lynda

On first installation of the sample app of iMessage Extension from apple the app icon visible, but after I uninstalled it and again installed the app, the app icon is not visible. Here is the screenshot and the apple sample app. https://developer.apple.com/documentation/messages/icecreambuilder-building-an-imessage-extension

I found a post that submitted the same issue, but the solution was not made public. I didn't get a reply to my comment at the bottom of the post, so I'm pasting the content of the post here. I am a developer working on iOS apps. I would like to report an issue occurring in iOS 18 beta and iOS 18.1 beta. Our company has two Enterprise accounts, and we are developing two apps: A app / TeamId: ABCDEFG B app / TeamId: HIJKLMN When we distribute these apps, which have different TeamIds, and install them on a device running iOS 18 beta, both apps install successfully, but only one app will run. (Other app crashed immediately after being launched.) This issue does not occur on versions prior to iOS 18. I would like to know if this is a problem that will be resolved in future updates, or if it is a policy change.

Hello, I’m working on a program that analyzes video files frame by frame to detect human poses in each frame. However, during the process of reading observations from the stream, the analysis frequently stops with the following error: [LOG_ERROR] /Library/Caches/com.apple.xbs/Sources/MediaAnalysis/VideoProcessing/VCPHumanPoseImageRequest.mm[85]: code -18 [LOG_ERROR] /Library/Caches/com.apple.xbs/Sources/MediaAnalysis/VideoProcessing/VCPHumanPoseImageRequest.mm[178]: code -18 The error was caught and printed using a do-catch block, and here is the output: Error Domain=NSOSStatusErrorDomain Code=-18 "Error: failed to processImage" UserInfo={NSLocalizedDescription=Error: failed to processImage} While the do-catch block helps prevent the app from crashing, the frames following the error cannot be analyzed. I’m hoping to understand the cause of this error, or find a way to skip the problematic frames and continue analyzing the subsequent ones. My development environment is Xcode Version 16.0 (16A242d) and iOS 18.0. Thank you for your help. (Attaching my code below.) let videoProcessor = VideoProcessor(videoURL) let bodyPoseRequest = DetectHumanBodyPoseRequest() let asset = AVURLAsset(url: videoURL) let videoTrack = try await asset.loadTracks(withMediaType: .video).first let bodyPoseStream = try await videoProcessor.addRequest(bodyPoseRequest) videoProcessor.startAnalysis() do { for try await observations in bodyPoseStream { guard let observation = observations.first else { continue } if let timeRange = observation.timeRange { /// do something... } } } catch { print("\(error.localizedDescription)") }
