안녕하세요.  
iOS SDK 를 사용하고 있습니다.  
저희쪽에서 MetaData의 Value를 “True” 혹은 "true"로 주고있는데,  
간혹가다가 getAllMetaData시  
`Could not cast value of type '__NSCFBoolean' (0x1b5905868) to '` `NSString`  
이런 Force TypeCasting 에러가 납니다.  
getAllMetaData시 [String: String]을 반환하는데  
Value가 True → Boolean으로 인식되어서, Bool → String으로 잘못 캐스팅 되는 거같아요.  
혹시 확인 한번 부탁드려도 될까요?  
저희쪽에서는 “true” or "True"를 사용하지 않을 예정입니다.

Sendbird 는 3.0.234  
SendBirdSyncManager는 1.1.40  
Cocoapods으로 사용하고있습니다.

추가로 숫자도 캐스팅이 실패할떄가 있는거같은데… 이것도 해결이 가능할까요?
