Hello, Is there currently any workaround to install and run an iOS 14.x simulator on macOS 26? So far, I have checked Xcode 26.2, and the oldest simulator runtime available there appears to be iOS 15.0. I may be missing something, so I wanted to confirm if anyone has found a way to use iOS 14.x on this macOS version. Thank you.

OS 26.s, Xcode 26.2 TLDR: My pure SwiftUI app freezes the window server, is this a known problem? My app is pure SwiftUI, no low level calls, no networking, no tricksy pointer use. Somehow, something in my code is terminally confusing the Window Server. As in, I run the app, and before I ever seen a window, the Window Server locks up, and is killed by the OS for being unresponsive. Using debugging shows that I get to the end of a Canvas, and it simply freezes upon exiting. I'm about to do the old comment out everything, and bring it back a bit at a time, but I'm wondering if anyone is experiencing this sort of thing? The reaction is so extreme. And it's not Xcode in particular, I built the program with xcodebuild, Xcode itself not running, and ran my app, and it did the same thing.

Hello! I have a web extension I've written to Google Chrome and Mozilla Firefox. It's made up of simple files. The extension (content.js) A manifest (manifest.json) file which explains the extension The icon (icon.png) Apple has developed App Store Connect / Xcode Cloud specifically for this. I upload those three files as a zip. I move it over to TestFlight for testing and then select Distribution to put it through Apple Review. This is my entire process. I have been doing this for 4+ months and Apple reviewed my application and put it up. I have then gone through 13 subsequent reviews (ALL POSITIVE) and have gone through version upgrades for months, no issue. On the 15th review, they want me to change the name of my application. I have done that in the content.js, the manifest.json, and anywhere that allows me to change it in App Store Connect. There is apparently one more place they want it changed. This is on the App Information / General Information tab, specifically the BundleID. The tip on that

Hi there, When I deploy my app to the iPhone for testing, I get the following error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the Please ensure that the certificates used to sign your app have not expired.

After appealing, Apple restored it at the end of last month. Currently, my Apple Developer account seems to be working fine. Today, I recreated the developer certificate and identifier, added the account in XCode, everything seemed fine, and I clicked the XCode button (Start the active scheme). The build was successful, but I got the error: Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The

Hi, I am reaching out to seek assistance with a persistent code signing issue that is preventing our team from installing our iOS app, Scoopz (https://apps.apple.com/us/app/scoopz-real-life-real-video/id6449206831) on physical devices.
