我可能不小心編輯了NSAttributedString.h類和/或相關類，現在看起來我的所有Xcode項目（包括我創建的項目都不會編譯） iPhone（iPhone 4s iOS版本：9.3.2）（我的部署目標是iOS 9.0）。多個Xcode項目將不能在真實的iOS設備上成功編譯
Xcode項目將成功構建並部署到模擬iPhone。
這是錯誤的編輯列表，我得到當我嘗試編譯應用程序爲iPhone：
System/Library/Frameworks/Foundation.framework/Headers/NSAttributedString.h:13:2: Prefix attribute must be followed by an interface or protocol
System/Library/Frameworks/Foundation.framework/Headers/NSAttributedString.h:16:1: Expected method body

我使用的Xcode 8測試版。
有沒有人知道會導致這個錯誤？
我試過重新啓動並重新連接iPhone，重新啓動Xcode，重新凝視我的Mac，並刪除DerivedData文件夾。我讀here，Expected method body可能是由代碼中的「雜散字符」引起的，但我無法找到一個流浪的字符。
這裏是NSAttributedString.h類：
