Hello, I released a new build for my app but it fails to run on iOS 12.5.8 (tested on iPad Air, iPhone 6, iPhone 5s). The launch storybard is shown, then the app stops abruptly. There is no crash log. It runs fine on iOS 13 or higher. Xcode 26.3 was showing a call stack (something with UIView) that did not include any app code. Now with Xcode 26.4 (and its new command line tools) there is an info popup with a debug metadata dump. However, I don’t intend to focus on Xcode here because it officially does not support iOS 12. It’s ok if I cannot debug, I just want the app to run on the device like the previous build did. Since there is no crash log, and the console is showing a bootstrap error, I believe my app code has not been executed and is therefore not at fault. Build 674 released on 23-Mar-2026: worked fine on iOS 12, built with Xcode 26.3 Build 675 released on 29-Mar-2026: Bootstrap error as describ
