Ios 如何在SceneDelegate中拥有颤振方法处理程序？

我有一个music Flatter应用程序，现在我正在swift中实现本机播放器代码。该应用程序与spotify ios sdk集成

我正在尝试运行，而spotify connect功能在IOS 13.6手机上不起作用，我发现IOS 13+更高版本需要SceneDelegate

现在我被困在如何在SceneDelegate中添加颤振方法处理程序中

当我在SceneDelegate上添加颤振方法处理程序时，我得到以下错误，它将被卡在断点处，下一步不会执行

我试图通过以下AVFoundation文档制作一个简单的视频取景器。应用程序每次启动时都会终止。如何解决此特定错误

Thread 1: EXC_BREAKPOINT (code=1, subcode=0x102d3c320)

以下步骤帮助我将颤振应用程序与SceneDelegate一起使用

创建

SceneDelegate.swift

包含子类

UIResponder

，并符合

UIWindowSceneDelegate

将

SceneManifest

添加到

Info.plist

，其中我们将SceneDelegate声明为场景的默认配置

更新

SceneDelegate.swift

以支持iOS 13+

颤振不支持SceneDelegate，将其与颤振一起使用是错误的做法

@available(iOS 13.0, *)
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    
    var window: UIWindow?
    //....

}
