It's weird, this code doesn't crash in an empty project, tested in Xcode 15 beta 8 + iOS 13.6 struct St { }; int main(int argc, char *argv[]) { @autoreleasepool { auto ptr = new St; NSLog(@"%p", ptr); delete ptr; return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class])); } }

Same: https://developer.apple.com/forums/thread/736572

This issue exists for at least 3 beta versions

Xcode 15 beta 8 still crash on new

Good, waiting for it
