@talka123456 @NSExceptional
if (!@available(iOS 16.0, *)) will waring that @available does not guard availability here; use if (@available) instead, because @available may only be used as condition of an 'if', 'guard' or 'while' statement, so you can fix like that

- (UIWindow *)statusWindow {
    if (@available(iOS 16.0, *)) {
        return nil;
    } else {
        NSString *statusBarString = [NSString stringWithFormat:@"%@arWindow", @"_statusB"];
        return [UIApplication.sharedApplication valueForKey:statusBarString];
    }
}
