Visual Studio Maui IOS

Hello, We don't have specific points of the app code where it may be crashing, since it's random, we already seen code crashing at very different locations around the app. Currently, about 5% of our users base is having this crash, also another detail, we are seeing this around different versions of iOS, not specific to iOS 18 or 26. We suspected at first about the compiler of new Xcode 26 (since this was the first version compiled with new Xcode), but it seems it is not that. We have sent a new build out today, compiled with Xcode 16.4, but no luck, still crashes. I'm attaching 2 screenshots, from the crashing stacktrace, one from Sentry and the other one from Xcode crash reporter directly. Also, attached the .crash file with the full stacktrace that can be found at Xcode. 2025-10-01_14-37-42.7083_-0500-2937c5ddef763873e9e26e42e243231a23e27df5.crash

It looks like iOS 26.1 introduces a legitimate API to detect this https://developer.apple.com/documentation/foundation/processinfo/isiosapponvision

Thank you for the helpful advice! I really appreciate you taking the time to guide me. I'll definitely follow your suggestions as I start my iOS development journey.

While it may be an issue with the app, it is absolutely an issue because of iOS 26 beta. When I posted this comment in the Apple Support Community, it was removed because it dealt with a beta level issue and was not appropriate for that forum. Any assistance would be incredibly appreciated because it continues to have this same issue since updating my watch and phone to iOS 26 beta.

That is, items indexed with indexSearchableItems(_:completionHandler:) fail to match textContent == something, regardless of whether contentType is unset, or set to .text, .plainText or .utf8PlainText. But ** == something does match. This is running on iOS 26.

I can tell you how I got into iOS development and try to answer some of your questions. I started by trying to find tutorials online, but the ones I found were either too simple or did not explain anything properly. I even bought a course at Udemy but that course also did not go into the details as much as I had hoped. I finally stumbled upon the iOS course at Stanford: https://cs193p.stanford.edu Back then it was available at iTunes U (which does not exist anymore), and included the lecture videos and the course work. I watched all the videos and, crucially, did all the course work. Doing the exercises was really essential because when you listen to the lectures it all sounds easy but when you try to do it yourself it's not so easy 😄 That course was exactly what I needed: it did not require any prior knowledge except for general programming, went into the details but explained everything. Definitely can recommend it if the videos are still made available, you will have to check. To your qu

Thanks for the post. I understand that you are encountering difficulties with your iOS build process. To assist you in troubleshooting and potentially resolving these issues, I recommend following a systematic approach: Update Xcode: Verify that Xcode is configured to utilize the most recent iOS 26 versions. Xcode 26.1 is the latest release at this time I believe. Update macOS: Ensure that macOS has also been updated to enable Xcode functionality. Examine Error Messages: Carefully review the error messages you are encountering. They can provide valuable insights into the underlying causes of the issues. Identify Specific Warnings or Errors: Look for any specific warnings or errors related to SDK mismatches, missing frameworks, or build settings. Please provide the error messages here. Please specify the simulator you are using. Please provide any specific error messages or additional context you can offer, and I will be happy to provide more targeted advice. Albert Pascual
