xcode真机调试提示错误：

Failed to prepare device for development

然后点击xcode windows-》Devices and Simulators==》查看该设备的详细信息：

NSLocalizedFailure = "This operation can fail if the version of the OS on the device is newer than the version of Xcode that is running.";

说明你的设备系统太高了，需要下载新的Devicesupport放入到Xcode的目录中。然后重启xcode

我的手机系统的是15.4，xcode版本是13.0

下载了15.4的Devicesupport放入到Xcode的对应的目录中/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
