Bug锦集
jitsi-meet-SDK文档几乎没有，出现错误几乎要耗费大半天时间。
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'
创建的JitsiMeetView 一直是UIView类型，调用JitsiMeetView的方法，就会崩溃，按照Unknown class JitsiMeetView in Interface Builder file.错误日志，google搜索的答案，一个也不能解决！
只能去github 提issus了，这是我反映的问题，并验证出了正确答案。
最新的jitsi-meet-SDK-iOS 适配了swift语言，所以需要 ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = YES。
