Bug錦集
jitsi-meet-SDK文檔幾乎沒有，出現錯誤幾乎要耗費大半天時間。
Unknown class JitsiMeetView in Interface Builder file. [UIView setDelegate:]: unrecognized selector sent to instance 0x7fcdbdd04420 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIView setDelegate:]: unrecognized selector sent to instance 0x7fcdbdd04420'
創建的JitsiMeetView 一直是UIView類型，調用JitsiMeetView的方法，就會崩潰，按照Unknown class JitsiMeetView in Interface Builder file.錯誤日志，google搜索的答案，一個也不能解決！
只能去github 提issus了，這是我反映的問題，並驗證出了正確答案。
最新的jitsi-meet-SDK-iOS 適配了swift語言，所以需要 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = YES。
