Latest Beta Version Breaks Xcode Testing Builds on Physical devices.
This is a grave issue I am facing while testing my apps on my personal device. This is the error I seem to be getting: The application could not be launched because the Developer App Certificate is not trusted. And on the phone side, this is the message: Unable to Verify App. An internet connection is required to verify the trust of the developer Apple Development... Before I receive any recommendations, such as deleting Xcode or restarting my device, I would like to clarify that I have already taken all necessary precautions. The application I was testing appeared to function correctly in the morning a few hours prior to the update. However, after upgrading to the latest beta builds, iOS 26.4 beta and the latest macOS beta, this issue has become a recurring problem. I would greatly appreciate your assistance in resolving this matter, as it is of utmost importance to me.

Orphaned XCode simulator disk images
Recently I noticed that although my drive showed ~800Gb of usage, the folders within totally to around ~600Gb (and yes I was including hidden 'dot' files/folders. After some inspection I found that there are a whole set of Disk Media Images, that appear to be related to XCode simulators.

Reply to Could not resolve host: static.rust-lang.org
This has been happening an awful lot for me lately as well. Here's an example error message: + rustup show Default host: x86_64-apple-darwin rustup home: /Users/local/.rustup info: syncing channel updates for 'stable-x86_64-apple-darwin' error: failed to download file error=Reqwest(reqwest::Error { kind: Request, url: https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256, source: hyper_util::client::legacy::Error(Connect, ConnectError(dns error, Custom { kind: Uncategorized, error: failed to lookup address information: nodename nor servname provided, or not known })) }) To debug I've tried hitting that same URL from Xcode Cloud using curl as well and get a similar DNS error, so it seems the error is with the Xcode Cloud DNS setup rather than rustup

ppq.apple.com returning 502 Bad Gateway - Unable to verify developer apps on device
Since this evening (March 10, 2026), I'm unable to launch any developer-signed app on my physical device (iPhone 16 Pro Max, iOS 26.4 beta 23E5223k). The error is: Unable to launch [app] because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user. On the device itself, it shows: Unable to Verify App - An internet connection is required to verify the trust of the developer. What I've tried: Created a new Apple Development certificate Deleted and reinstalled the app Restarted the device Tested on both Wi-Fi and cellular Confirmed Developer Mode is enabled Removed all third-party CA certificates from the device Verified the code signature is valid (codesign -dv shows correct Authority chain) The root cause: https://ppq.apple.com is currently returning 502 Bad Gateway.

Reply to Linker trying to link Metal toolchain for every object file on Catalyst
Based on the above I tried reproducing this with a test project. And lo! it’s trivial to reproduce: I started with Xcode 26.3 without the Metal Toolchain 26.3 component installed. I created a new project from the iOS > App template. In the General tab of the target editor, I removed the Mac (Designed for iPad) destination. And added the Mac (Mac Catalyst) destination. I selected My Mac (Mac Catalyst) as the run destination. I chose Product > Build; the project built without any warning. In Xcode > Settings > Components, I installed the Metal Toolchain 26.3 component. I chose Product > Clean. And then Product > Build. I now see a build warning: ld: warning: search path '/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.3.7003.10.hJke6J/Metal.xctoolchain/usr/lib/swift/maccatalyst' not found Given the above, I can only conclude that this is a bug.

Per the Xcode 26.3 Release Notes, Xcode 26.3 supports on-device debugging in iOS 15 and later. iOS 12 is no longer supported target for running your app with the debugger attached.

First experience with App Store Connect
This is my first time submitting an app to the App Store. I uploaded a build through Xcode a few days ago, but no build is visible in my app record on App Store Connect (nor are any builds listed in the TestFlight tab). I haven't submitted the app for review yet, because I assumed it needs a build attached first. Did I miss a step in uploading the build?
