I'm testing a video stream (HLS) with AVPlayer. On XCode 14.3 and simulators running iOS 16.4, there is no video image, only black screen. The audio is playing normally, also progress/duration of the video is showing as expected. The problem does not occur on same XCode version with earlier versions of the simulator. Is this a simulator bug? I've also tested it on real device with iOS 16.4 - no problem there.

Since Xcode 15.3 it has become impossible to build our project more twice in a row without encountering a batch of "internal inconsistency error: never received target ended message for target ID …".
This issues appeared a few months ago (15.0 i think, but i'm not sure), but xcode 15.3 makes it almost unusable. We're a team of 3 iOS devs, and we're all having the problem.
Our project involves a lot of SPM packages, a few cocoa pods, a few iOS Frameworks, and a bit of swiftgen. Nothing particularly special for a large project, and no custom build steps that does anything fancy.
It is now to the point where we're looking for alternative to xcode, because we can't decently kill xcode and restart every time we have to build our code...
Hi,
When launching my app on the iOS 18 simulator using Xcode 26 beta, the app crashes immediately with a missing symbol error:

Notes:
I have only tested on the iOS 18 simulator so far.
I have not yet tested on earlier iOS versions or physical devices.
The app runs fine on iOS 26 simulator using Xcode 26, so the crash seems specific to the iOS 18 simulator.
This looks like a system symbol that may not be linked properly in the iOS 18 simruntime.
Is this a known issue with the iOS 18 SDK or simulator runtime in Xcode 26 beta?
Thanks!

I had no issues previously with my iPhone 13 Pro running iOS 18 and my XCode 15. Now, after switching to the iPhone 16 Pro, it won't work.
I've tried restarting my phone several times, quitting XCode, removing and readding developer mode—nothing quite works.
I have been working for a while now. Never encountered this issue. After accepting the invite from the organization. The organizations does not appear at developer apple account. But can see the organization at app store connect. Yes i have checked the account permissions. I have the admin role and developer role etc is checked everything is correct. This is not just me happening with my colleague as well.
I’ve noticed a strange bug in Xcode 16 and Swift. When a preview is rendering and hasn’t finished yet and you run an app to debug, Xcode is launching two instances of the app. Has anyone else noticed this issue? If you let the preview finish rendering before running the app, this doesn’t happen. Very odd.
WKWebView based apps crash in today's Xcode 16.4 iOS 18.5 simulator with messages including:

Hi,
i have met error below when i tried to po one attributes of an instance in my Xcode lldb:
error: type for self cannot be reconstructed: type for typename "$xxxxx" was not found (cached)
error: Couldn't realize Swift AST type of self. Hint: using `v` to directly inspect variables and fields may still work.
Is there anybody met the same error before? I urgently want to know why this happen and how to fix this issue.
My macOS Version is Sequoia v15.0.1, Xcode16.0. This problem showed after i upgraded my macOS and Xcode version.
XCode 13 is super slow, build time is 10~20 times longer than Xcode 12。The worst release ever.
Xcode 16.2 runs well, but encountered the problem in Xcode 16.3.

I have installed Sequoia and Xcode 16 and now I can't add packages to my (or any project). I just get a message saying the package can't be resolved. Basically I can't carry on developing.
SORT THIS OUT APPLE
I updated Xcode and MacOS recently and haven't been able to compile my Flutter app on iOS devices/simulators since then. The error keeps changing every time I run it but here's one of the output in the terminal after running flutter run:

What I have tried so far:
Deleting iOS SDK and simulators
Cleaning Xcode build cache using cmd+shift+k
Creating a new Flutter project and trying to compile it (it failed so that reduces the chances of it being a Flutter issue)
Clearing the DerivedData folder
Clearing settings and cache of simulators
Restarting laptop

Xcode: 16.0

I have had this notice for a while: Registration is being processed for these devices. They may become available for development and ad hoc distribution in 24 to 72 hours. Changes to device availability will appear in the Status column.
The status for my new iPhone has been stuck in this "Processing" state. See image:
I have a project I've been working off of for a few years now that makes use of local Swift Packages. In my workspace, I have a "Kit" project that generates a framework using several local Swift Packages as dependencies.
In Xcode 12, the local Swift packages resolve correctly and compiles, but each beta of Xcode 13 gives me the error:
"[ProjectName].xcodeproj Missing package product '[LocalSwiftPackage]'"
Clearing the package cache, derived data, or restarting the application does not resolve the issue. Only Swift Packages that are remotely loaded from a URL are compiled correctly.
Using local packages to separate module code, while still being able to edit in the same project, has been essential to my workflow and would hate to see Xcode 13 release with these breaking changes, and I have not seen this issue listed in the known issues for the Xcode 13 release notes.
Has anyone else experienced this issue or found a workaround?

I'm not able to download my Private key since Yesterday and I get the following error message when I click on "Download"
Auth Key can only be downloaded once. This auth key has already been downloaded.
I revoked all my existing keys and created new ones and I get the same error message. I tried all the mentioned solutions on this forum and StackOverflow like using Safari,turning off VPNs,removing spaces from Key name, using my iPhone, using a Mac, incognito/private mode on Windows Microsoft Edge, clicking done then pressing download after, right clicking on download Linked File as...nothing seems to work
Hi there,
I uploaded an update bundle for the posted app, but I got a rejection message.
ITMS-90048: This bundle is invalid - Your archive contains paths that are not allowed: [._Symbols]
The XCode version I'm using is 16.2, and I've been trying to find a route using Run Script and Finder, but I don't know what the hell it is about.
Does anybody know what could cause this issue?
Any help would be appreciated.
Thanks.
I am using the latest version of Xcode 16, and I have created a GPX file in my project. However, I am unable to see or select the file to simulate the GPS location. I have attempted to uninstall and reinstall Xcode completely, but the issue persists. Has anyone encountered a similar problem? How can I resolve this? Thank you.
My application uses a text file with an extension of .dssfilelist. On Linux I would register the Mime type and associate it with the application in the .desktop file.
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
<mime-type type="text/dssfilelist">
<comment>DeepSkyStacker file-list file</comment>
<glob pattern="*.dssfilelist" />
</mime-type>
</mime-info>
I believe that I need to add stuff to the Info.plist for my application, but I also understand that CFBundleTypeExtensions is deprecated.
So please could you show me what I now need to add to the Info.plist file so that these files will be registered as "text/dssfilelist" type and associated with my application and to associate a .icns file with it?
ChatGPT in Xcode 26.1 is super slow for me. What used to complete in a batter f seconds is now taking tens of minutes.
Context: M2 Pro MBP, Xcode 26.1, macOS 26.1. CPU stays under 50% while ChatGPT returns. Using the minimal setting. Tried restarting, have verified I have nothing running Electron, no other apps are running.
ChatGPT returns fast for the displayed content but the preview window where it renders code per line takes a few seconds per line.
