Hi, I have a certificate, how can I display the certificate content in my Mac app just like Keychain Access app does. Can I popup the certificate content dialog just like Keychain Access app?

Hi, after 2 years of not updating my app on appstore i wanted to submit an update for my iOS app which also containts a watch app target. When i try to submit it to upload it i get the following errors: Failed registering bundle identifier The app identifier "(myappBundleID).watchkitapp" cannot be registered to your development team because it is nit available. Change your bundle identifier to a unique string to try again. No Profiles for "(myappBundleID).watchkitapp" were found. Xcode culdn't find any iOS App Store provisining profiles matching "(myappBundleID).watchkitapp" Since i have my app already in store with that bundle identifier i don't know why it can not be registered to my team. Also i don't want to change the bundle identifier because then i can not publish it as update to store.

Hello, On macOS 26 (Tahoe), when building a OSX app that includes GameKit code, calling GKLocalPlayer.local.authenticateHandler shows the "Sign In to Game Center" alert (e.g. didShowFullscreenSignIn) — even if the app does not have the Game Center capability enabled or any related entitlement (com.apple.developer.game-center). This alert only appears when the user is not signed in to Game Center in system settings. However, when testing the same code path on iOS app built with macOS 26 (Tahoe), the alert does not appear unless the proper capability and entitlement are included. This behavior is different from macOS 15 (Sequoia) + Xcode 15.x. Prior to the update, Game Center features did not work at all even with the OSX app without Capability and Entitlements. Steps to Reproduce Create a new OSX app target (App Sandbox enabled, no Game Center capability). Add minimal GameKit code: GKLocalPlayer.local.authenticateHandler = { _, _, _ in } Build OSX app and run on macOS 26 (Tahoe). Ensure Game Center is signed out in System Settings. Observe: “Sign In to Game Center” alert appears automatically. Expected Behavior When Game Center capability and entitlement are not present, authenticateHandler should fail silently, and no signIn alert should appear. Actual Behavior On OSX app, the Game Center signIn UI appears even without any Game Center capability or entitlement. On iOS app, this alert does not appear. *Build Configuration: built with the same condition. (macOS 26 + Xcode 26) Question Could you please confirm whether this behavior is an intentional change in macOS 26 or a bug only for OSX apps in the GameKit authentication flow? Thank you.

We are using three column split view as root of our app and wants to hide the supplementary column alone in some cases and behaves like two column split view. With the existing apis we are unable to achieve this since it hides primary column as well and not giving expected results. .hide(.supplementary) setViewController(nil, for: .supplementary) But seen this behavior in Native Notes app when using the View as List and Gallery option. is there any way to achieve this with maintaining three column split view itself ?

We have received several cases that our app can not display uitableview cell in iOS26, but users said that they can select cells with single tab and the uitableview didselectcell delegate can response！ I have reported a feedback but no response. Does anyone have the same bugs with me？ You guys can see that the page is blank, I have a video a user sent to me can proved that he can select cell with gesture. We cannot reproduce the bug and don't konw how to fixed, we think this is the bug with iOS26, so here for some help. This bug block our distribution of new version(support iOS26) This is the feedback https://feedbackassistant.apple.com/feedback/20677046

Hi, Not sure how to describe my issue best: I am using SwiftData and CloudKit to store my data. In the past, when I tested my app on different devices, the data would sync between the devices automatically. For whatever reason this has stopped now and the data no longer syncs. No matter what I do, it feels as if all the data is actually stored just locally on each device. How can I check if the data is actually stored in the cloud and what could be reasons, why its no longer synching between my devices (and yes, I am logged in with the same Apple ID on all devices). Thanks for any hint! Max

'm trying to write my own stack, and the issue I'm encountering is how to get the child content of a ForEach. // // ContentView.swift // test // // Created by cnsinda on 2025/10/18. // import SwiftUI public struct MyStack<Content: View>: View { var content: [Content] public init(@MyStackBuilder<Content> content: @escaping () -> [Content]) { self.content = content() } public var body: some View { VStack { // I expect to get 9, but it always returns 1. Text("count:\(content.count)") } } } @resultBuilder public enum MyStackBuilder<Value: View> { static func buildBlock() -> [Value] { [] } public static func buildBlock(_ components: Value...) -> [Value] { components } public static func buildBlock(_ components: [Value]...) -> [Value] { components.flatMap { $0 } } // hit public static func buildExpression(_ expression: Value) -> [Value] { [expression] } public static func buildArray(_ components: [[Value]]) -> [Value] { components.flatMap { $0 } } static func buildFinalResult(_ components: [Value]) -> [Value] { components } public static func buildExpression(_ expression: ForEach<[Int], Int, Value>) -> [Value] { expression.data.flatMap { index in [expression.content(index)] } } public static func buildEither(first: [Value]) -> [Value] { return first } public static func buildEither(second: [Value]) -> [Value] { return second } public static func buildIf(_ element: [Value]?) -> [Value] { return element ?? [] } } struct ContentView: View { var body: some View { ZStack { MyStack { ForEach([100, 110, 120, 130, 140, 150, 160, 170, 180], id: \.self) { item in Rectangle().frame(width: item, height: 20).padding(10) } } } .frame(width: 600, height: 600) } } My expectation is to get each individual Rectangle(), but the actual result is that the entire ForEach is treated as a single View. What should I do?

We've identified a regression in iOS 26.0 and 26.1 Beta 4 where AVSpeechSynthesisVoice(language:) no longer respects user-selected voices from Accessibility settings. Issue: When users select a specific voice in Settings → Accessibility → Spoken Content → Voices, calling AVSpeechSynthesisVoice(language:) returns the system default voice instead of the user's selection. This worked correctly in iOS 18.6.2. Particularly affects: Third-party speech synthesis voices (CereProc, Grammatek, etc.) Apps relying on automatic voice selection based on user preferences Example: // User selected CereProc Heather for en-GB in Accessibility settings let voice = AVSpeechSynthesisVoice(language: "en-GB") print(voice?.name) // iOS 18.6.2: "HEATHER", iOS 26: "Daniel" (system default) Interesting observation: The new Accessibility Reader feature in iOS 26 correctly uses the user-selected voice, but Tap to Speak and the API both ignore the setting. Tested methods: AVSpeechSynthesisVoice(language:) AVSpeechUtterance auto-selection Reflection for new APIs All return the system default voice, not the user's preference. Filed: FB[20271264] Has anyone else encountered this? Any known workarounds to programmatically access the user's preferred voice selection?

We have observed a per-process limitation on the number of simultaneous nw_connection_t objects in certain macOS environments. On some systems, this limit does not appear to apply, but on others the limitation is reproducible. When a process attempts to establish a large number of connections (e.g. 512+), some connections enter the nw_connection_state_waiting state and report the POSIX error “Cannot allocate memory”. These connections remain stuck indefinitely, even after other connections are deallocated and resources should theoretically be available again. This behavior severely impacts use cases such as transparent proxies implemented via the NetworkExtension framework, which intercept system-wide traffic and must open connections on behalf of all client processes. In this scenario, a per-process limit effectively becomes a system-wide limit, leading to unexpected and hard-to-diagnose network failures in client applications. So, is there any way to disable this restriction for Network Extension processes? Are there any system settings that could affect this limitation and be modified by users?

When a VPN is active, RCS messaging does not work on iOS 18. I work on an iOS VPN app, and we were very appreciative of the excludeCellularServices network flag that was released during the iOS 16 cycle. It's a great solution to ensure the VPN doesn't interfere with cellular network features from the cellular provider. Separately - As a user, I'm excited that iOS 18 includes RCS messaging. Unfortunately, RCS messaging is not working when our VPN is active (when checking on the iOS 18 release candidate). My guess is that RCS is not excluded from the VPN tunnel, even when excludeCellularServices is true. It seems like RCS should be added in this situation, as it is a cell provider service. Can RCS be added as a service that is excluded from the VPN tunnel when excludeCellularServices is true? (I've also sent this via feedback assistant, as 15094270.)

I have a problem with my client's account. I can't let internal testers download a test build from TestFlight. When they want to install there's this 2 alert popping up: "The requested app is not available or doesn't exist" This problem happens on both the app that is not published yet, and the app that is in Appstore already. I checked and there's no any pending agreement. Another problem is when I try to submit the build for External tester review it shows the error message (that doesn't really helping at all) like this:

Hi everyone, My app was recently rejected during App Review because it’s missing screenshots for the 13-inch iPad display size. However, I don’t currently have access to a 13-inch iPad device, and I’m not sure how to generate or capture the correct screenshots. I’ve already provided screenshots using simulator for 13 inch iPad, which I thought they will accept, but they didn't. Could anyone please advise on: How to create valid 13-inch iPad screenshots without owning the device? Its really troubling me while its time for app review. Any guidance or workaround would be greatly appreciated.

Dear Apple Developer Support, I’m developing a Chromium-based iOS browser and want to open the Safari settings page (Settings → Apps→ Safari) like Chrome’s “Import data from Safari” feature, where clicking “Go to settings” opens the Safari settings page. To reproduce this behavior in Chrome: 1.In Chrome, search “Import password from Safari.” 2.Restart Chrome. 3.Go to Chrome → Settings → Safari import → Import to Chrome → Go to settings. 4.You will see it opens Settings → Apps → Safari. Please see the attached file for steps to trigger this feature in Chrome. My attempt with App-Prefs:root=SAFARI only opens the Settings main page ,Is there a public API to open the Safari settings page directly? Look forward to your reply,many thanks

Since around September (iOS 26 release), i'm unable to test my app normally. It says "internet connection is required to verify [my certificate id]", or just crashing. All terms and conditions accepted, everything is valid, certificates are OK. Reinstallation via xcode does not help. Removal of provisioning profile, generating new does not help. Revoking of certificate and generating new does for around week, then it happens again, but do i need to do it every week now? In logs i see the following: default amfid validation failed because of missing trust and/or authorization (0xe8008026) error amfid not valid: 0xe8008026: The provisioning profile requires online authorization. error amfid Unexpected MISError (0xe8008026): The provisioning profile requires online authorization. default +0300 amfid /private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib not valid: Error Domain=AppleMobileFileIntegrityError Code=-400 "An unknown error was encountered" UserInfo={NSURL=file:///private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib, NSLocalizedDescription=An unknown error was encountered} default kernel AMFI: code signature validation failed. It looks like apple validation servers are not working, or is it iOS bug? All provisioning profiles are showing like "valid" in apple developer center. My network is not behind a proxy, connection is direct. If use EXACTLY the same app, signed with the same provisioning, same signature, on another test device, it works! When i reset current device to default settings and installing the EXACTLY same app after it, it works as well. Looking for a help from apple developer support

Good day! Have anyone experienced sudden crashes increase cause by CALayerInvalidGeometry · CALayer position contains NaN: [nan 5] that gets set via -[AVMobileGlassVolumeControlsView layoutSubviews]? 94% of crashes belong to iOS 26.0.1, while rest to 26.0.
