IOS 之错误记录

文章目录

• • • 1、相机权限：This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.
    • 2、Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window.
    • 3、'statusBarOrientation' was deprecated in iOS 13.0: Use the interfaceOrientation property of the window scene instead.
    • 4、DYLD_LIBRARY_PATH=/usr/lib/system/introspection，DYLD_INSERT_LIBRARIES=/Developer/usr/lib/libBacktraceRecordin
    • 5、`where` clauses are preferred over a single `if` inside a `for`. (for_where)

1、相机权限：This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

• 在 info.plist 添加键值对 “Privacy - Camera Usage Description” —— YES（值不能为空，随便填个值就行）

2、Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window.

• 问题：
• 1、iPhone 系统版本12.1.2，Xcode 13.1。运行代码显示iPhone’s iOS 12.1.2 doesn’t match Playza.app’s iOS 13.0 deployment target
• 2、升级 iPhone 系统版本到最新版本15.3.1后，运行代码显示Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window.
• 3、在 Xcode 中快捷键 command + shift + 2，显示Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window. Failed to prepare device for development
  4、搜索网上资料，在stackoverflow网站上发现有前辈遇上到同样的问题组合（iPhone 15.3.1 + Xcode 13.1），对方将 Xcode 升级为 13.2 解决问题。但因为约定 Xcode 版本需要统一进行升级，故换了一部低于 15.3.1 版本的手机。
  Xcode error: Failed to prepare device for development

3、‘statusBarOrientation’ was deprecated in iOS 13.0: Use the interfaceOrientation property of the window scene instead.

• 解决：

extension UIWindow {static var isLandScape: Bool {if #available(iOS 13.0, *) {return UIApplication.shared.windows.first?.windowScene?.interfaceOrientation.isLandscape ?? false} else {return UIApplication.shared.statusBarOrientation.isLandscape}}
}

4、DYLD_LIBRARY_PATH=/usr/lib/system/introspection，DYLD_INSERT_LIBRARIES=/Developer/usr/lib/libBacktraceRecordin
