Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time.
I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck.
The game runs fine in Unity, but not so much in Xcode.
Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated.
Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode.

I can see that iOS beta 2 was released yesterday. I'm not running the beta yet on my actual iPhone, but I wanted to see if an issue I reported in beta 1 was fixed.
Is there a way to update my iOS 26 simulator for beta 2? Usually, there's a new Xcode download that includes the new simulator, but it looks like the most recent Xcode beta release was June 9.
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?
When a static library is built with Xcode 26 (with deployment target set to iOS 13) and then linked into an app project compiled with Xcode 16, the build process fails with the following linker error:
Undefined symbols for architecture arm64:
"_swift_coroFrameAlloc"
This occurs even though both the static library and the app project have their deployment targets set to iOS 13.0. The static library works on Xcode 26, but fails to link on Xcode 16.
This issue shows up with certain Swift syntax. For example, in my case, using a property getter and setter caused the compiler to emit a reference to _swift_coroFrameAlloc, which in turn triggered the issue.
This issue prevents us from distributing pre-built static libraries compiled with Xcode 26 to teammates who are still using Xcode 16.
I’ve filed feedback for this issue (FB21130604).
Is there any way to work around it? For example, by adding specific Build Settings or something similar?
A demo project is available here: https://github.com/Naituw/SwiftLibraryDeploymentTargetIssue
The demo project includes:
StaticLibraryProject: A simple Swift static library with property getter setter usage
AppProject: An iOS app that links against the static library
verify_compatibility.sh: An automated script to reproduce the issue
Method 1: Manual Build and Verification
Open StaticLibraryProject/StaticLibraryProject.xcodeproj in Xcode 26
Build the StaticLibraryProject for iOS device (Release configuration)
Locate the built libStaticLibraryProject.a in the build products directory
Copy libStaticLibraryProject.a to AppProject/AppProject/ directory
Open AppProject/AppProject.xcodeproj in Xcode 16
Build the AppProject for iOS device
Method 2: Automated Script
Edit verify_compatibility.sh to configure the paths to your Xcode installations:
Set XCODE_26_PATH to your Xcode 26 installation path (e.g., /Applications/Xcode.app)
Set XCODE_16_PATH to your Xcode 16 installation path (e.g., /Applications/Xcode16.app)
Run the script: ./verify_compatibility.sh
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

Hi! I was wondering if anyone else encountered similar issues and what the solution ended up being.
We're encountering weird sign-in issues on our iOS version of our app. It seems like an uninstall and reinstall solves it, but the issue seems to only impact users who underwent the transfer process from one iOS device to another. What I am curious about:
What is copied over from one device to another in this process?
Is there a way outside of owning multiple test devices to replicate this flow?
Our current suspicion is that NSUserDefaults is not being cleared by our app on first start, and that stale data is copied over during this transfer process, breaking the sign-in until a re-install wipes everything properly.
Does it seem like we're on the right track with this assumption, or completely out to lunch?
I have static libraries and headers of a C++ project that I believe are correctly built for iOS and iOS Simulator destinations. The C++ project is built via CMake with something like:
cmake dirName \
-G "Unix Makefiles" \
-B buildDir \
-DCMAKE_INSTALL_PREFIX=installDir \
-DCMAKE_SYSTEM_NAME=iOS \
-DCMAKE_SYSTEM_PROCESSOR=arm64 \
-DCMAKE_OSX_ARCHITECTURES=arm64 \
-DCMAKE_OSX_SYSROOT=$(xcrun --sdk iphonesimulator --show-sdk-path) \
-DCMAKE_OSX_DEPLOYMENT_TARGET=15.0
...
cmake --build buildDir --config Release --target install
I believe those are all the important parameters. This gives me a static library (.a) and headers that I believe should be compatible with arm64 iOS simulators, and I do this same thing for x86_64 architecture with simulators and for actual iOS non-simulator via the iphoneos SDK path.
I'm pretty sure this gives me the correct static lib and headers. Let's assume it does because I'm not able actually create the XCFramework to know if they're right. This does work with a macOS lib and headers, but I need iOS for this library. How do I package this into an XCFramework now?
This Apple developer articles says I should be a able to create an xcframework via xcodebuild -create-xcframework -library libName.a -headers include but when I try to do this with my my iOS arm64 simulator static lib I get:
error: binaries with multiple platforms are not supported '/Users/.../install/ios-arm64-simulator/libName.a
But, when I run: lips -info libName.a I get Non-fat file libName.a is architecture arm64, so, I'm not sure what to do here. Trying to extract arm64 from that static library also produces an error as it it is just an arm64 lib.
I'm not really sure what's going on, but from reading online this specific command, xcodebuild -create-xcframework is a consistent pain point in the process of trying to get an XCFramework, and the seemingly only workaround is to archive a framework project and then create the xcframework via xcodebuild -create-xcframework -archive MyFramework.xcarchive -framework[or -library].
However, how am I supposed to get this static lib and headers into a suitable xcodeproj so that I can archive it correctly? Everytime I try to copy the headers and static lib into the Framework xcodeproj and set what I believe are all the correct settings, my .xcarchive is always empty.
Does anyone have any advice here on how to get this to work?
The main impetus for trying to get this C++ static lib and headers into an XCFramework as that seems like the only valid way to link a 3rd party C++ lib to an SPM package and have the C++ package be interfaceable with Swift.
Under macOS 26 and iPadOS, the Help menu in many cases has a menu item for "App Help". This item has the following icon:
I need to use this in my own app. I am unable to find this icon in SF Symbols 7 beta. I've scanned all of the icons under "What's New". I've searched for "help", "light", and "bulb" and this icon does not appear.
Does anyone know if it's even a new SF Symbol? Or does anyone know of a way to use this icon?
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? Since the old app never went into production I don't see why that would be a problem
Hello,
Good morning to you all. Please I need a guide on how to change my app icon on the developer account. Necessary steps would be appreciated
Thanks for the anticipated assistance.
Best Regards
Biggie

I’m developing an app that uses Family Controls to block other apps. I’ve already received approval from Apple for the entitlement, and everything works perfectly when I run the app from Xcode on a physical device.
However, when I upload the same build to TestFlight, the app installs and runs, but the Family Controls functionality doesn’t work — it seems like the entitlement isn’t being applied in the TestFlight version.
So I’d like to ask:
👉 Do Family Controls entitlements work automatically on TestFlight builds, or is there any additional step required to enable them?

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!

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.

Hi, I'm investigating what looks like possibly nondeterministic behavior when linking large iOS app binaries. I do not have a concise reproduction of the issue yet, but am trying to hunt down possible leads. In particular, the problem appears to surface when invoking clang to link a binary and the resulting order of the 'branch island' instructions appears to be random each time the binary is linked (as shown by the link map output). I was wondering if anyone with insight into the linker's current implementation could shed light on whether that is expected, and if there is anything that can be done to prevent it. FWIW, it seems like it might be size-dependent as smaller app binaries don't appear to exhibit the same behavior. I'd be glad to share more specifics and hopefully a reproduction if I can ever find one eventually. Some environment info (Xcode 16.4 toolchain):

In MetricKit, a metric payload comes in with a time range which usually means it contains multiple launches/sessions. How can we relate things that will change between launches or sessions such as pid and lowPowerModeEnabled from the metadata. Will there be multiple payloads for each unique value or is there some other way to use this?
I have added 2 command line tools in my swiftUI app for macOS, it was working fine locally, but it gives error when i try to make archive of it. I am not sure about the reason, but it was related to sandboxing the command line tools, after this i have tried multiple solutions but i am unable to resolve this issue, how should i handle the helper command line tools

With the latest (26) version of Apple's developer tools, is there a way to manually attach a debugger (other than lldb) to an iOS app launched with "devicectl device process launch --start-stopped"?
In the past, this was possible via the ios-deploy third-party tool (now defunct), which provided a debugserver port. This information is notably missing when using devicectrl – although the process ID of the launch process is provided, and the tool is clearly aimed at letting you launch and attach to processes from the command line.
lldb can, of course, attach via its built-in support for this using the device set of commands. But I'm explicitly looking for a way to attach my own debugger via the GDB-compatible debug proxy.
I am a developer working on an iOS enterprise application. When I deployed the release version to my device, it crashes upon startup. It works fine in debug mode on my device.
The app is an upgraded version of Xamarin Form to .NET MAUI.
I have attached a crash report.
I would appreciate any help/insights on how to resolve.

We are trying to setup Apple Unity Plugins, in out project we have a handful of developers who contribute to the project via git.
When building and importing plugins via tarball (as instructed in the Github repo) the package clearly points to local path, so once pushed all members encounter the error:
An error occurred while resolving packages:
Project has invalid dependencies:
com.apple.unityplugin.accessibility: Tarball package [com.apple.unityplugin.accessibility] cannot be found at path .....
When trying to actually move content to the package folder (same way as any other unity plugins is setup) and add it as "embedded", it works fine on local machine, but team members will get a few of errors:
[Apple Unity Plug-ins] No Apple native plug-in libraries found.
DLLNotFoundException: AppleCoreNativeMac assembly ...
No Apple Native plug-in libraries found.
Moreover AppleCoreNativeMac.bundle is flag as not verified and deleted by macOS.
What is the right way to setup unity plugins in a project used by multiple members via sourcetree ?
Routinely I'll have additional questions when browsing the Apple Developer Documentation. Would be really convenient if we could just submit that feedback from the documentation webpage itself, Apple could have the data, and potentially down the line address it; but at least you'd have the data.
For example, I'm looking at the documentation for AttributedString: https://developer.apple.com/documentation/foundation/attributedstringprotocol/index(_:offsetbycharacters:)
Now, I would like to know what would happen if the distance brought the position past the end, what would be returned. Because it's non-optional which I imagine would imply nil would be returned if the parameters were invalid. But it doesn't say.
I run into these small missing behavioral details with some regularity and imagine others do as well. It would be really great if we could just submit that discrepancy and perhaps see some numbers on the page of the total number of discrepancies submitted or something so we can see that it's not just us and have some peace of mind that based on the amount of feedback submitted there's a higher chance that this discrepancy will be addressed in the future.
