I have a project that leverages XPC and has interoperability between Swift and Objective-C++. I am presently getting a compile-time error in one of our unit test targets, of "Argument passed to call that takes no arguments" on the following code:
let interface = NSXPCInterface(with: XPCServiceDelegate.self)
My XPCServiceDelegate protocol is defined as:
@objc(XPCServiceDelegate) public protocol XPCServiceDelegate {
//...
}
For the longest time, this code has compiled successfully, and it has not recently changed. There are two confusing things about this error. The first is that I have a different build scheme that will compile correctly other code with the same structure. The other is that I have team members that are able to compile my failing scheme successfully on the same XCode version, OSVersion, and branch of our repository.
I've attempted numerous things to try to get this code to compile, but I've run out of ideas.
Here's what I've tried:
Clean build both on XCode 16.4 and XCode 26 Beta
Delete DerivedData and rebuild on XCode 16.4 and XCode 26 Beta
Delete and re-clone our git repository
Uninstall and reinstall XCode
Attempt to locate cached data for XCode and clear it out. (I'm not sure if I got everything that exists on the system for this.)
Ensure all OS and XCode updates have been applied.
The interface specification for NSXPCInterface clearly has an initializer with one arguement for the delegate protocol, so I don't know why the compiler would fail for this. Is there some kind of forward declaration or shadowing of NSXPCInterface? Do you have any ideas on what I could try next?
I have os_log statements in my app. With my phone connected to the Mac, when I run the app through XCode, open Console app, those logs are shown. However, when I'm launching the app on its own, those logs don't appear in Console (phone still connected).
Am I missing something very basic? Please help.
Hi,
I developed an app and trying to publish but at the validation state i'm getting two errors.
The errors as follows:
(1) App record creation failed due to an invalid input. Request failed with the error code "STATE_ERROR.APP_CREATE.PLATFORM_NOT_ALLOWED_DUE_TO_CONTRACT_STATE", and reason "One or more platforms cannot be created for this app due to your provider's contract state. Creation of apps for the platform(s) iOS is not available due to your provider's contract state."
(2) App record creation failed due to an invalid attribute. Request failed with error code "ENTITY_ERROR.ATTRIBUTE.REQUIRED", and reason "The provided entity is missing a required attribute You must provide a value for the attribute 'companyName' with this request"
Which inputs and attributes are causing these errors?
Thanks in advance.
Up until now, it was possible to check in build scripts via the ENABLE_PREVIEWS environment variable whether a build for a SwiftUI preview is being executed.
In addition, it was also possible to conditionally compile code for SwiftUI or exclude it from compilation using this variable.
This no longer works with Xcode 16 and the new SwiftUI Preview compilation!
There is still the option to switch to the old system with the "Use Legacy Previews Execution" setting, but as stated in the release notes, this option will be removed at some point.
Which brings us back to the old problem of not being able to exclude build scripts from preview builds and not being able to prevent certain code from being compiled / add special code for SwiftUI previews.
This is a terrible situation, especially for more complex projects in which precisely the points mentioned are important for the build process.
I seriously hope Apple provides us with another environment variable for SwiftUI preview builds that we can use.
I've been happily building and deploying my app to my iPhone and Watch S8, and the app was ready to submit to App Store Connect last night. However, when archiving it I got an error saying that my DynamicEventSelectionIntent was in multiple extensions. It was, kind of. When I started working on the complications I copied the Widgets intents into the complications, and left the name the same, but they were not in multiple targets.
It looks like the info plist only had one item in the IntentsSupported (because they're the same name), so I decided to rename them so I had a widget one and a complications one.
The problem I have now is that I can't deploy to my iPhone and Watch anymore because I'm getting this error:
This app contains a WatchKit app with one or more Siri Intents app extensions that declare IntentsSupported that are not declared in any of the companion app's Siri Intents app extensions. WatchKit Siri Intents extensions' IntentsSupported values must be a subset of the companion app's Siri Intents extensions' IntentsSupported values.
All I've done is rename one intent, and locate every instance of it in the info plist files, and add the appropriate new one into the right places.
Here's what I've got. Main App contains Widget and WidgetIntentHandler, plus Watch App, which contains Complications and ComplicationsIntentHandler.
Target: Main app: (I've removed everything that has no bearing on extensions.)
Target: Widget:
Target: WidgetIntentHandler:
Target: Watch App:
Target: Complications:
Target: ComplicationsIntentHandler:
Please, can someone tell me what should and should not be in the various parts, as I've tried for 12 hours now and I cannot get this to deploy to my iPhone anymore :( Thanks.
Since a few days, I'm trying to fetch our private SPM repo hosted on Azure via Xcode but without success. Actually they now accept only ssh key RSA-SHA2-256 or RSA-SHA2-512.
So I created a new SSH key, but it seems the problem persists when I try to fetch spm repo or git clone via xcode:
"You’re using ssh-rsa that is about to be deprecated and your request has been blocked intentionally. Any SSH session using SSH-RSA is subject to brown out (failure during random time periods). Please use rsa-sha2-256 or rsa-sha2-512 instead. For more details see aka.ms/ado-ssh-rsa-deprecation. remote: ERROR_SSH_UNSUPPORTED_CIPHER (7) (-20)"
Even so I'm choosing the good new ssh key, it seems Xcode is sending wrong information about the new generated ssh key.
Anyone is experiencing the same here?
Today's Xcode release won't download the visionOS SDK, gives a 'network error'.

I've got a large and complex app which has several dependencies upon 3rd party libraries (installed as pods).
The app is structured according to Model-View-Controller design and there is a requirement to implement the Model part as an .xcframework so it can be included and used in the original app along with a few new apps.
However, Apple documentation states that umbrella frameworks are not supported (Technical Note TN2435).
The Model code has several dependencies which would be totally unfeasible to replace or remove, for example it uses RealmSwift for database storage. Obviously it would be impossible to write one's own database storage scheme in place of using Realm.
However, if my framework uses Realm as a dependency, then its now become an umbrella framework.
So therefore not supported according to Apple documentation.
So what are options/solutions?
Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.
Hey,
I've updated to both Xcode 26 Beta 4 and MacOS 26 Beta 4. Both run super stable so far.
However, every time I use Xcode Previews for a few minutes, the entire system freezes for a few seconds and then crashes and reboots.
I'm trying to generate a system diagnosis (which it offers me after the reboot), but it seems to be stuck generating.
It's hard to say what exactly causes the crash, unfortunately. But it happened multiple times after starting to use Xcode Previews.
Anyone else has that problem?
I've also filed a feedback for this: FB19013059

I have a SwiftUI app that I've been working on in XCode 16.1. The project builds and runs in the simulators, on my mac and on my iPhone/iPad without any issues. I'm also able to build my unit test project and run them without any errors. The project has zero warnings in it.
When I go to the Edit Schemes options and change the Run scheme to be a Release build with the Debug Executable unchecked I get a compiler error:
Command SwiftCompile failed with a nonzero exit code
I've attempted this Release Run with the following target devices in XCode:
My iPhone 15 Pro Max (iOS 18.2 Beta 3)
MacBook Air (M1) (15.2 Beta)
iPhone 16 Simulator (iOS 18.1)
Any iOS Simulator Device (arm64, x86_64)
All 3 of these target have the same issue. Normally I would just debug the error from the logs but when I look at the build output I can't see any information in the log to tell me what happened. It looks like the source files are sent into the SwiftCompiler and the compiler fails without bubbling up the issue.
I've provided the full error log export as a Gist HERE due to it's size. Is there anything in the log I'm missing? Is there a way for me to turn on more verbose logging during compilation of a Release Build?
I created a brand new Multiplatform App in XCode and I added all of my source files to it. No project configuration settings were changed. I could build it successfully with the debug configuration. I then changed it to the Release configuration and experienced the same error. I can create another fresh project and make the same release configuration with none of my source files in it and get a successful build. I
t seems there is something wrong with my source files and the release configuration but the compiler doesn't indicate what. I'm lost at this point as I can't figure out how to get a release build and can't seem to find any indication as to why.
On iOS 18.0+ simulators, tap any share link button from any app, select "Save to Files", the "Save" button is disabled.
In all previous simulator versions this works. This behavior even happens with default Apple apps like Photos.
Simulator: Version 16.0 (1037)
XCode: Version 16.1 beta (16B5001e)
macOS: 14.6.1 (23G93)
I've been getting intermittent failures on Xcode code compiling my app on multiple platforms because it fails to compile a metal shader.
The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again.
Sometimes if I re-run it, it works fine. Then I'll run it again, and it will fail.
If you tell me to file a feedback, please tell me what information would be useful and actionable, because this is all I have.
I reinstalled the macOs from macOS recovery, Then installed the new Xcode 15, Everything worked fine but when I tried to commit my code the commit button does not showing.
The image from my Xcode app:
with iOS 18.4. I and my colleagues are unable to launch the app.

I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets.
The source editor persistently displays a “No baseline average for Time” message.
Has anyone else encountered this? Figured out how to sidestep the issue?
Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down.

Hi,
I'm testing out Xcode 16 beta and I have a couple of questions:
Is Swift Assist only available on Sequoia? I see that predictive code completion is per https://www.apple.com/newsroom/2024/06/apple-empowers-developers-and-fuels-innovation-with-new-tools-and-resources/, but I tried the beta on Sonoma and I'm not seeing it
Regarding Swift Assist - I understand that code is only used to process requests and never stored on servers, and Apple will not use it to train machine learning models. However, my company's security team may still decide that using Swift Assist is too much of a risk. How can we disable it across multiple developer machines?
Thank you!
