I am developing a game that has 3 team members. I can manually start up 3 simulators and run the game for developing/testing but seem like there should be a simple way to click build/run and have it launch on all three automatically. Does anyone know how to do this or if its even possible without writing some scripts?

I'm trying to improve my build time on macOS by not building for x86_64. I've got the following settings: This gets Xcode not to build x86_64 for my app, but not all the package dependencies. I've updated most of the packages to swift-tools-version: 6.0 but FlatBuffers is still on 5.8 and .macOS(.v10_14). GPT claims: If your deployment target is set to macOS 10.15 or earlier, Xcode may force x86_64 support for compatibility reasons. But Xcode is building x86_64 for ALL my packages, even the ones that don't depend on FlatBuffers. When I open a package in Xcode that depends on FlatBuffers, then it builds arm only, so that may be a red herring. Not sure what else to try.

I have a VPN installed (Global Protect) on my company computer, which is a MacBook Pro M2, to access the company network, internal URLs, websites, and run the app I work on. However, even with the VPN installed, I am having trouble accessing certain resources. The solution found was to manually configure the proxies for my Wi-Fi network. After configuring the proxies, I was able to access all the company's URLs and everything I needed. However, the Xcode Simulator is not picking up these network configurations, and when I try to run the project, it does not work. How can I solve this?

I have had content blockers in the Mac App Store for years. Ever since moving to Sonoma, doing a clean build or archive in XCode deletes the extension from Safari settings since it never gets into the built app. The only way for me to get it back is to remove the DerivedData and target, reboot, and create a target with a different name. That works and stays around in Safari settings as long as I only build and don't clean. However, a clean or an archive removes it again. Restoring a version of the project from Time Machine that was posted to the App Store weeks or months ago doesn't work. However I can download the version of the app in the App Store, and it works, but I can't build it now from the source code that was used to build that version without going through the above process. Moving from Sonoma 14.7.1 to 14.7.2 didn't work. I would move to Sequoia if I had reason to believe that would work, but I don't. Safari 18.2, Sonoma 14.7.2, 32GB, 2.2 GHz 6-Core Intel Core i7

I tried \s+$ to find trailing spaces, but it seems the IDE code editor behaves strangely - it locates random lines that obviously has no trailing spaces. Did I misunderstand regex in the editor?

I’m experiencing an issue in Xcode 16 where the app randomly builds and runs in the simulator while I’m designing items in the storyboard. Here’s what I’ve tried so far to stop this behavior: Disabled "Show Live Issues" in the General settings Removed all key bindings related to Build & Run in the Key Bindings settings Checked for unintentional shortcut triggers, but nothing seems to be causing it Update XCode from 16.1 to 16.2 Delete Derived Data Despite these actions, Xcode still automatically builds and launches the simulator at unexpected times, disrupting my workflow. Is there any setting or hidden configuration that could be causing this? How can I completely prevent Xcode from running the simulator automatically while editing UI in the storyboard? Would really appreciate any guidance on this!

I upgraded xcode to 16.2 and found that the txt file generated by Write Link Map File is different from before, no longer containing detailed data. So, how to set it up to obtain the same link map file as the previous xcode version. # Path: /Users/....../xxx.app/__preview.dylib # Arch: arm64 # Object files: [ 0] linker synthesized # Sections: # Address Size Segment Section 0x00004000 0x00000000 __TEXT __text # Symbols: # Address Size File Name

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

What I want? I expect to use xcrun devicectl device process launch --device <uuid> <bundle-identifier> --payload-url <URL> to launch my app and pass the specified URL as I usually do in iPhone. What I do? Let's say the app A which I'm developing. I try to use UIApplication.open(:options:completionHandler:) in another app to open the app A with registered schema. And whether app A is cold launch or background resumption, app A can go foreground with receiving URL. If I use xcrun devicectl as above described, app A can still be opened. However, app A can't receive URL which I pass through --payload-url option. That's different from in iOS. BTW: I as well try YouTube with UIApplication.open and xcrun devicectl, the former way work, the latter way not work.

I can’t view energy reports in the Xcode Organizer. I keep getting the message “An error occurred while downloading energy reports. Please provide a valid value” Feedback ID: FB16595567

Since upgrading from Xcode 15 to 16, we have been experiencing a build error during compilation. Building on Xcode 15 still works with no issues. The error happens only on the first build after a clean. Subsequent builds succeed. This is an issue because our CI process archives the project from a clean slate, and this causes it to fail every time. I will attempt to describe the issue and include information I believe is relevant in this document. The error occurs on this import line within an Objective-C file during the Scan Dependencies step of compiling. This line imports our custom Objective-C to Swift bridging header file - "Swift2Objc.h". Our custom Objective-C to Swift bridging header file is simply wrapping the project’s auto-generated Objective-C to Swift bridging header file - "KWISwift.h". The error is specific to the import of the OfflineServices Swift Package. Specifically, the OfflineServices-Swift.h file - the Swift Package’s auto-generated Objective-C to Swift bridging file. Module JRE not found - the exact error (Also included as text on the bottom of the post) JRE is a third-party library provided to us as an xcframework. It is placed directly into our Swift Package as a binary target. The xcframework itself is composed of .a file and a Headers folder which includes header files and a module.modulemap. The module.modulemap file looks like this.

Hi, This maybe somewhat confusing, but please bear with me. I currently have an app in the App Store that supports iOS and tvOS. But the tvOS version was a separate app during the development process. I'd like to combine the iOS and tvOS app into one project so its easier to handle and keep track of internally. Can I upload the new Apple TV version to the same place where the current one is, or would I have to delete the current Apple TV version before uploading the newly combined version? I hope I made that clear enough :-) Thank you, Dan Uff

I updated the icons in Xcode to customize the appearance of my app icons to be light, dark, or tinted. The app is allowed to be downloaded and run on iPadOS. The app icon behaves as expected on iOS however the app icon does not change on the iPad. Am I missing a step for the iPad? To be clear the app does not target iPadOS rather it is just running the iOS version. Thanks kof

I've used SPM to install some dependencies, however for one of them, CocoaLumberjackSwift the Embed section is blank and attempting to click in it doesn't brink up any dropdown menuetc. Why is that, how can I change it or check what its set to if its blank? (Code 16.2)

I've been using XCode for development in C++ for several years. Suddenly, today it started having the following problem: Any time I try to compile my code, (even if I just finished successfully compiling it), it spends several minutes running CLangStatCache. This is according to the result of "Perform Action... Build with Timing Summary". Furthermore, if I first delete the ".../DerivedData/SDKStatCaches.noindex" folder, the problem goes away and it compiles immediately. However, it creates a new folder with a 32 Mb file in it, and then has the same problem the next time unless I delete that folder again. I do not want to have to delete this file every time I compile my code. Is there some way to turn this off? What happened that is different today from any other day in the last several years? I did just download and install the latest System software update, including XCode... Did that break something?

The following function could run several hundred times with no problem but will occasionally cause a EXC_BAD_ACCESS (SIGBUS). The last time it was a KERN_PROTECTION_FAILURE perhaps meaning it is trying to write to a read only memory but previously it was KERN_INVALID_ADDRESS. I have tried debugging tools to no avail. Can anyone see any reason why the following function could be causing this. Just in case the function is a red herring the only other thing that was running is a AVQueuePlayer that contains 11 tracks, but the crash happens mid song making it unlikely. The function includes running other functions so below is all related functions that happen as a result of a swipe gesture. func completeLeft() { let add1 = Int(tiles[Square - (squares2move + 2)].name ??

Hi everyone, I’m trying to detect if Developer Mode is enabled on iOS 16+ devices using Swift but haven’t found any official APIs or documentation for this. Are there Apple-recommended ways to achieve this, or is it restricted for privacy/security reasons? Thanks!

I tried dragging an apns file for a live activity into my simulator to begin a Live Activity. It didn't do anything. I didn't see it mentioned in the wwdc videos either. So I'm wondering if this experience is not yet developed, or maybe I'm doing something incorrectly?

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts
