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?

Hi, Some crashes downloaded from TestFlight aren't symbolicated by Xcode and I don't know why, here's an example: Although all uploaded builds contain debug symbols (Symbols directory with .symbols files) and other crashlogs in the same version are symbolicated just fine (also visible on the above SS). I have access only to the .symbols files but not to the original dSYMs and I wonder how to perform symbolication manually. I tried pointing atos and symbolicatecrash utilities to respective .symbols file, but they are unable to work with it. I'm sure it's possible as TestFlight symbolicates crashlogs using only .symbols files somehow. Could you give a hint?

There was a time that Apple Developer Documentation provides a filter to show the changes across versions, at https://aninterestingwebsite.com/documentation/technologies , with purple (modified), green (added), and red (deprecated) annotations. I wonder if this feature is completely removed, or is it still hiding somewhere? It is helpful to diff the API changes among versions. Thanks. edit: as pointed out by Rick, here is an archive link to what it used to look like

Hi, I am developing IOS(Android App) with React Native. I am very confused about cocoapods and pod and how to correctly install it on my new Macbook Pro M4. I am not using bash but I am using zsh. Note, actuallywhich pod return nothing During the preparation of my environment, it say CocoaPods is one of the dependency management system available for iOS. CocoaPods is a Ruby gem. You can install CocoaPods using the version of Ruby that ships with the latest version of macOS. the web site show two commands gem install cocoapods sudo gem install cocoapods I saw another command as well brew install cocoapods During different processes, I experienced several time the following error (Command 'pod install failed) Command pod install failed. └─ Cause: pod install --repo-update --ansi exited with non-zero code: 1 Then I am confused about cocoapods and pod. Are both he same? With my previous MacBook pro, I spend time to install cocoapod on my profile because Ruby was not the latest version on the system. But apparently, on my new Macbook Pro M4, the command ruby -v return (as well) ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.arm64e-darwin25] The current stable version is 4.0.0. I bought a new macbook pro M4 and I reinstalled node and all package for Rect Native 0.81 a expo 54 excepted cocoapods. Now, I need to configure the push notification and it's time to install cocoapods as it's require here But on my new macbook pro, I would like to make sure I do it correctly and I kindly ask your help and recommandation to install Ruby and cocoapods/pod Q1: Should I install cocoapods with brew install cocoapods or gem install cocoapods? Q2: what's is the difference or the common point with cocoapods and pod? Cocoapod web site said If using the default Ruby included with macOS, installation will require you to use sudo when installing gems As ruby -v print 'ruby 2.6.10p210', I suppose, I should not install cocoapod with sudo You can use a Ruby Version manager such as RVM or rbenv to manage multiple Ruby versions, or you can use Homebrew to install a newer Ruby with brew install ruby. As far I understand, I should not install cocoapods with the Ruby version of the system, then I suppose the command Q3: Will 'brew install cocopads' install the latest version on my profile? Will it upgrade the system version Q4: What will do the command brew install rbenv ruby-build rbenv install 3.2.2 (or better: rbenv install 4.0.0) in comparison with brew install ruby My guess I suppose that the following will help, but it would nice if you could correct me and clarify # All should be done in my profile brew install rbenv ruby-build echo 'eval "$(rbenv init - bash)"' >> ~/.zprofile source ~/.zprofile rbenv install 4.0.0 # rbenv global 4.0.0 # What is it? ruby -v gem install cocoapods Q5: But then, what about pod and the error message Command pod install failed. As you can see, I am a bit confused and I would appreciate your clarification I thanks you for your help and clarification and I wish you a happy new years

This is from an Xcode generated file. var values: [String] = [] let exp = Expectation() let c = pub.filter { $0 != nil }.map { $0! }.sink( The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.

I added an Apple Watch app target for an iOS app. If I install it directly through Xcode it runs, however it seems to be able to communicate with iphone through Watch Connectivity framework and once I close the app it seems to uninstall itself from the watch. When I installed the iphone app frist, the app does not show up on the available apps on the iphone Watch application, what could be the issue ? The iphone app was created using react native through expo. Testing Devices Iphone 13 pro max IOS 26.0.1 --- Apple Watch Series 4 WatchOS 10.6

Is this a valid thing to include in the Info.plist file? If so is a category of public.app-category.astronomyvalid? I couldn't find that, but the categories I did find seemed very limited.

So, as we found out from WWDC, the migration to Apple Silicon is inevitable. Does anyone have a good recommendation for a replacement for Macintosh Common Lisp on Apple Silicon? I was using it back in the MPW days and struggling to keep the Lisp code working, but Apple Silicon has thrown a money wrench at it! Thanks in advance for any advice on any available Apple Silicon Lisp development tools!

Hello, Thank you for taking the time to read this and hopefully helping me. https://apps.apple.com/gb/app/gdl-graded-darts-leagues/id1592502150 I created a mobile app using AppPresser that is connected to my WordPress website. The iOS app is logging users out when they close the app and go back to it. The login session does not persist, and users are forced to log in again frequently. This happens at any time period between closing and opening the app. This only happens on iOS — Android keeps the session active as expected. I don't know if I've included this post in the correct topic, sorry. Thanks again for any ideas and assistance!

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!

Hello All, I used to own an app named LOLIIPOP, and am in the process of transferring it to my new apple account. I am having two problems.... How do I transfer the source code and binary to my new apple account? My developers have an old code, so I need to send them the LAST code they uploaded to the App Store. How do I do that as well??? Please any help!!! Thanks, Mr. LM

I am a developer with a free developer account, and my account is under the legal age of majority. I know that, according to the terms in Section 6 of the Apple Developer Agreement, I must be the legal age of majority to use pre-release software, and yet the Software Update section of Settings on my device would allow me to install a beta release of iOS 26. Is there a way for me to hide/remove this option without signing out of my account, and not have it appear again as an option until I reach the age of majority?

By default, it seems 15.6 is shipped with git version 2.39.5 (Apple Git-154) I was wondering when Apple will ship a Git version above 2.43 to resolve this vulnerability. Git Carriage Return Line Feed (CRLF) Vulnerability (CVE-2025-48384) https://github.com/git/git/security/advisories/GHSA-vwqx-4fm8-6qc9 You can install Homebrew then install newer versions of git using Homebrew; however that installs in a new location so the vulnerability is still present as the native version is behind and updated by Apple during software updates Thanks

Hi, I am using Installer JS in Distrtibution file which is created using productbuild command. I am trying to read the installed version of app from the plist file present in the /var/db/receipts folder. It gives the following warning. If I enable the flag , notarization will fail. FJS: Package Authoring Error: access to path "/var/db/receipts/com.xxx.xxx.plist" requires Following is the function I have used to read the installed version. system.files.plistAtPath() I have also tried the following function to read the version from .app file. system.files.bundleAtPath Both the functions give the warning. Is there are a way to avoid this warning or a better way to read the installed version? Regards Prema Kumar

I'm running the latest iOS 26 beta 5 on my iPad and iPhone. Whenever I run these betas, I always get the message below telling me an update is available (whenever I plug in my devices). I'm assuming this is because the update check is detecting that I have something other than the latest production release. Obviously, it makes no sense to ask me to update to a prod build when I'm running the dev beta. Is there a way to turn this message off? Or maybe Apple could handle this situation better? Or maybe it's just a bug and I'm the only one getting this message?

Hi, experts, I want to find Siri response window by bundle id and use it for checking or printing, here is my example code: XCUIDevice.shared.siriService.activate(voiceRecognitionText: "call mom") let siriApp = XCUIApplication(bundleIdentifier: "***") // Print out text from siriApp, // expecte print: "Sorry, I can't make a phone call with your iphone." Where should I put into ***? I tried "com.apple.SiriViewService", "com.apple.siri.velocity", "com.apple.springboard' but nothing work Any suggestion appreciated, thanks!

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?

I want to create a dynamic library for my iOS project, which would be loaded at runtime. In Xcode, there are templates available for creating a static/dynamic lib for MacOS. But under the iOS tab, there is only a "static library" template. So, I used the "static library" template and in its build settings I changed the Mach-O type to "dynamic library". Now after building it, I use the file command on the generated file and it tells me it is a dynamic lib. But the generated file still has .a extension, which is usually for static libs. I'm aware we can tell Xcode in build settings to change the .a extension to something else, say .dylib but this seems like a hacky way to create a dynamic library. What is the correct way? I am aware that standalone dylibs are not supported on iOS, and we need to wrap them in a framework. For my use case, the framework will literally be a wrapper, it won't have any source files of its own. It should only contain the dynamic lib generated from some independent codebase. I am not sure how to place the dylib in the framework.

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!
