推荐答案

我在使用xcode归档应用程序时遇到此错误-在sim上运行并且物理设备正常工作-但我的物理设备仍被选作方案.解决方案对我有用:清理构建文件夹，然后选择"Generic IOS Device"作为方案.

I got this error when i was archiving my app with xcode - while running on sim and physical device worked -, but had my physical device still selected as a scheme. Solution worked for me: clean build folder, and select 'Generic IOS Device' as the scheme.
