Apple SDKs should provide libunwind_ext.h on macOS
(Copy pasted from FB17261080 that I submitted) Hi: Apple's SDK (libSystem.B.tbd) provides definition for multiple symbols(__unw_add_dynamic_fde / __unw_add_find_dynamic_unwind_sections ), but doesn't provide corresponding headers, available in LLVM upstream as libunwind_ext.h We need such headers to write Exception-Enabled JIT Framework for macOS

Missing Sources in Apple OSS Distributions
I noticed that there are numerous missing source repositories. For instance: https://github.com/apple-oss-distributions/IOHIDFamily/blob/07b14847cb5b4e0f826a3970961624969e443a6e/IOHIDFamily.xcodeproj/project.pbxproj#L4274 Many files referenced in the xcodeproj are listed but do not actually exist in the repositories.

Error build expo EAS
I'm trying to create a new build from VSC through EAS (expo) but it's failing and returning the error I'm attaching. I'm running the command eas build --profile preview --platform ios. I have an "App Manager" account, my colleague has the same role and he can do builds normally. I have other permissions and accesses ok, as can be seen in the attached picture, but apparently I have the issue in "register bundle identifier". Does anyone faced the same issue? How can I solve this? What step I'm missing? Thanks in advance!

Can I get notified when my watchOS app is terminated by the system (e.g. watchdog)?
Hi all, I’m developing a watchOS app and have seen cases where the app is terminated by the system — for example, due to CPU usage limits being exceeded (watchdog termination). Here’s a portion of one of the crash reports: Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: CAROUSEL 2343432205 <RBSTerminateContext| domain:10 code:0x8BADF00D explanation:[app<app_name>:898] Failed to terminate gracefully after 5.0s ProcessVisibility: Foreground ProcessState: Running WatchdogEvent: process-exit WatchdogVisibility: Foreground WatchdogCPUStatistics: ( "Elapsed total CPU time (seconds): 11.280 (user 9.800, system 1.480), 100% CPU", "Elapsed application CPU time (seconds): 5.162, 46% CPU" ) reportType:CrashLog maxTerminationResistance:Interactive> My questions: 1.) Is there any way to get notified (via Crashlytics, Xcode Organizer, or any other reporting mechanism) when this type of system-level termination happens — similar to how we’re notified of crashes? 2.)Is there any way for a watchOS app to receive runtime warnings from the system when it’s about to exceed CPU or memory limits — similar to UIApplication.didReceiveMemoryWarningNotification on iOS? Thanks in advance!

How do I determine whether a framework contains bitcode?
Hi there I've recently had my upload rejected in Xcode Organizer as a result of one of the frameworks we use containing bitcode. Error: [ContentDelivery.Uploader.XXXXXXXXXX] Validation failed (409) Invalid Executable. The executable 'Sam.app/Frameworks/Foo.framework/Foo' contains bitcode. Is there an accurate way to determine whether an .xcframework contains bitcode ahead of time without using Xcode Organiser? My current methodology is below, please can I get some confirmation that this is accurate, or suggest a more efficient approach? I have concerns about my approach and whether it throws false positives for empty bitcode markers. 1. get original framework size 2. run xcrun bitcode_strip -r framework_path -o temp 3. get new framework size 4. if new size is smaller than original, then it contains bitcode Thanks for the help, Sam

NSUbiquitousContainers
I'm using Xcode 16.3 and I want to add the key "NSUbiquitousContainers" but I cannot do it in the Entitlements file, it should be in info.plist file! I have done it before but in previous versions of Xcode when the info.plist was in the project navigator. However, now I cannot find the file and I did not find any way to create it! Please guide me in detail how to proceed (I'm not new to Swift or SwiftUI but not familiar to project settings)?

Apple Support for Xcode error
Hello, We tried calling Apple support who suggested they cannot help and work thru emails and discussion forums to resolve the technical issue we are facing to post our first App in App Store. I have given admin level credential to my son (minor) allowing him to incorporate his Xcode to App Store with his credentials. Apparently, he keeps getting error he does not have enough credentials to do so and we are unable to proceed further. I acknowledge I am not a developer & Apple support team was unable to help, I wonder if there is specific support channel I need to follow to resolve the issue. His App is going to help is Robotics team in upcoming event and we appreciate if someone can kindly point me to right direction to resolve the matter at earliest.

SwiftTesting
I am using Swift Testing for TDD my project. I have a struct that contains an array of 65536 UInt8's along with other properties. I am testing methods that modify the properties of the struct including the contents of the array. In just one of my test files, any test fails (there are several in the file), the entire contents of the struct, including the array, are printed to the console. In another test file they are not. I'm don't think there are any differences to the test setup in the two files. Any idea what's going on? I'm able get the program to skip the dump to the console by copying the properties I want to test to local let constants and testing those. Thanks

Is there a way for two users to make development builds on separate accounts for one app?
Tech stack: React Native + Expo. We are using two solo developer accounts (not a business or team account). Context: Friend and I set out to make an app together. Friend created app and set it up on Apple. We worked on it together. He controlled devops (builds and submission). Friend no longer can commit to development. Wants to transfer to me. I create apple developer account. After app transfer, my phone (deviceid) underwent a 14 day soft ban preventing builds. That has since been lifted. There seems to be something in place preventing me from making dev builds on the original dev bundleid. It says it's still owned by him despite the app transfer. Bottom line: what needs to happen so 1 can make dev builds? nice to have: is there a way for us to both make dev builds under the same bundleid?

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:

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?

Flutter build fails on iOS physical device in Android Studio, works in Xcode
Hello, I'm encountering an issue when trying to build and launch a Flutter app on a physical iOS device using Android Studio. Here is the full log: `Launching lib/main.dart on (iPhone Name) in debug mode... Automatically signing iOS for device deployment using specified development team in Xcode project: (Project ID) Running Xcode build... Xcode build done. 19.7s Failed to build iOS app Could not build the precompiled application for the device. Error (Xcode): Target debug_unpack_ios failed: Exception: Failed to codesign (Project Names)/build/ios/Debug-iphoneos/Flutter.framework/Flutter with identity (identity ID). Error launching application on (iPhone Name).` This only happens when using Android Studio. When I build the same project using Xcode, it runs fine on the same device. Background: I accidentally deleted all Apple accounts from Xcode recently. In Keychain Access, I had three identical certificates; I deleted the older two and kept the newest one. I suspect this may be related to provisioning or code signing, but I’m not sure how to resolve it within Android Studio. Any advice or steps to fix this would be greatly appreciated. I created a new test project in Xcode using the iOS > App template, enabled automatic signing in Signing & Capabilities, and selected my team.
 I then tried building and installing the app on a real device, and it worked successfully.
 This confirms that there are no issues with code signing or provisioning on the Apple side.
 Thanks in advance!

App Crashes instantly in Test Flight
Hi everyone! I recently developed an app (sort of a social media app), built in React Native Expo. I have finally after months of coding, completed the App. It works completely fine and passes all my testcases on multiple devices. It has also passed Apples review and after a few tries become stable on all their devices. However, when I released it to TestFlight, it opens and crashes immediately? I have tried numerous fixes, error boundaries etc. but to no avail. I am really struggling here, I can't seem to replicate the error at all even in Xcode. It seems to just crash on open where the splashscreen flashes, not sure why? I have attached the crash report and redacted the TEAM_ID and DEVICE_ID. Any help would be greatly appreciated. Warm regards, Hassan | Founder @ Oneforge GymBuddiesConnect-2025-01-21-013038.txt

Unable to start podman, the error is: NSLocalizedFailure = "Internal Virtualization error."
This morning I installed podman on my new Apple laptop. It can be inited successfully but failed to start. The error is: Error: Error Domain=VZErrorDomain Code=1 Description="Internal Virtualization error. The virtual machine failed to start." UserInfo={ NSLocalizedFailure = "Internal Virtualization error."; NSLocalizedFailureReason = "The virtual machine failed to start."; My new Mac laptop with the latest OS version: 15.3.1 and it is Apple M4 chip. I verified that my Virtualization.framework is good by ls -l /System/Library/Frameworks/Virtualization.framework also my MacOS support virtualization because sysctl kern.hv_support returns kern.hv_support: 1. I tried to install it on my old Apple laptop which is intel core, same OS version - everything is good. How to fix this issue?

Localizing your apps
TL;DR version: AkVox - “Your App in Your User’s Language” Quickly and easily localize your app into as few or as many languages as you want with AkVox. Longer version: AkVox can localize any Xcode project. Simply drag your Exported Localizations folder into AkVox, click translate, then export, and you’re ready to import the translated localizations catalogs back into Xcode. Alas, you cannot import the whole localizations folder as one, you must import each catalog individually, a process that takes around 10 seconds per language. AkVox can also assist you when you’re ready to publish your app on App Store Connect. You can create a list of texts you will enter to promote your app and AkVox will translate them. Again, you can’t apply all your translations to the App Store in ne go, you have to apply each language individually. To make this task less painful, AkVox has a convenient set of buttons to make the copy and paste process as quick and simple as possible. The same arrangement is available when you come to add “mini texts” during setting monetization subscriptions. AkVox employs Google Cloud Translate which means you will need an API Key to be able to run full translations. However, Google offers a generous monthly allowance of 500,000 characters to be translated for free each month. This may well mean that you don’t ever pay for the translation process, just the very low price to use AkVox. The free version of AkVox simulates translating by substituting jumbled versions of Hamlet’s “To be or not to be” speech – this is instead of utilising what would normally be used in this case, the tediously dull Lorem Ipsum text. To see AkVox explained in detail, go to the website: https://akvox.com/
