이 자습서 (https://www.youtube.com/watch?v=Q6qcrO8uNzU&feature=youtu.be)를 수행했습니다. 아래는 마지막에 생성되는 코드입니다. 그러나 getShifts.findObjectsInBackgroundWithBlock { (objects:AnyObject[]!, error:NSError!) -> Void in

나는 AnyObject[]!
을 [AnyObject]!
과 같이 넣어야한다고 말하는 오류가 발생하지만 그저 오류를 만듭니다. 어떤 아이디어?

정확한 질문이 무엇인지 모르겠지만 xcode가 구현을 기반으로 제안을 생성 한 경우 제시된 나머지 오류를 통해 제안 및 문제를주의 깊게 관찰하는 것이 좋습니다. AnyObject에 대한 올바른 구문을 삽입 한 후 오류가 정확히 무엇입니까? [AnyObject]가 실제로 무엇을하고 있는지 [HERE] (https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/WorkingWithCocoaDataTypes.html)를 검토하십시오. NSArray 검색 – soulshined
