一款在iOS 9-15上成功运行的应用程序,在使用Xcode 13.1(在M1 Pro上升级后)构建时,在iOS 9-12上启动时崩溃。
由于使用了仅存在于iOS 13+上的UITabBarAppearance,因此在主storyboard解档时崩溃(请参见下面的跟踪)。我的storyboard入口点是一个Tab Bar控制器。
自从以前的Xcode版本中在iOS 9-15上工作时,我没有编辑过我的storyboard文件,而且崩溃发生在我的任何代码运行之前。
希望这只是模拟器问题(我没有旧的iOS设备),我将其上传到商店,但该应用程序在iOS 12及以下的真实设备上启动时也会崩溃。https://apps.apple.com/nz/app/campermate-australia-nz/id1586561660
最低OS目标为9.0。我们可以放弃对iOS 9-11的支持,但我们仍然有许多iPhone 6和5用户(他们仅限于iOS 12)。
我该如何解决这个问题?
