真机测试的时候，遇到的两个问题，不知道是哪里出现问题，先记录一下这个问题。
- App installation failed, This application or a bundle it contains has the same bundle identifier as this application or another bundle that it contains. Bundle identifiers must be unique.
- This app contains an app extension that specifies an extension point identifier that is not supported on this version of iOS for the value of the NSExtensionPointIdentifier key in its Info.plist.
