使用 Xcode 13 构建后，应用程序在 iOS 12 及以下崩溃
App crashes on iOS 12 and below after building with Xcode 13
在 iOS 9-15 上 运行 成功的应用现在在 iOS 9-12 上使用 Xcode 13.1 构建时在启动时崩溃（在 M1 Pro 上) 我刚刚升级到。
由于使用了仅在 iOS 13+ 上存在的 UITabBarAppearance（请参见下面的跟踪），它在取消归档主故事板时崩溃。我的故事板入口点是标签栏控制器。
我没有编辑我的情节提要文件，因为这是在 iOS 9-15 和以前的 Xcode 版本上工作，并且在我的任何代码运行之前发生崩溃。
希望这是一个仅限模拟器的问题（我没有旧的-iOS设备）我上传到商店但应用程序在真实设备上启动时也在 iOS12 上崩溃及以下。 https://apps.apple.com/nz/app/campermate-australia-nz/id1586561660
最低 OS 目标是 9.0。我们可以放弃对 iOS 9-11 的支持，但我们仍然有很多 iPhone 6 和 5 用户（仅限于 iOS 12）。
我该如何解决这个问题？

UITabBarAppearance was introduced in iOS 13, so it won't work with older iOS versions. Check your code for any occurrences of UITabBarAppearance and either remove them or wrap in an if #available。这也可能是故事板在内部使用 UITabBarAppearance 的问题。
XCode 在我不知情的情况下偷偷将这些插入了我的故事板文件！
<tabBarAppearance key="standardAppearance"/>
和
<navigationBarAppearance key="standardAppearance"/>
删除这些修复了它！
我在版本检查中的代码中为 iOS13+ 设置了外观。
我通过在构建阶段手动将 LinkPresentation.framework 添加到“Link Binary with Libraries”并将其状态设置为 Optional 来解决此问题。
