我有一个我无法解决的问题。 我声明以前它没有问题。 用 Xcode 14.2 打开它做一个小更新，现在当我尝试应用程序时，我总是在 AppDelegate 中遇到同样的问题：Xcode 14.2 应用程序委托问题 - 无法识别的选择器发送到实例 0x7f80740e4800。 我不知道我必须纠正什么，在“主要”中没有任何改变，插座连接等已被删除。 我认为这是新版本的问题。 任何人都知道我该如何解决它？ 谢谢。

@罗布 我也试图理解错误，因为它始终有效并且没有进行任何更改。 自从我升级到 xCode 14.2 进行更新后，我收到了这个错误。 这是 recipeviewcontroller 的内容：
