스크립팅 브리지를 사용하여 osx 응용 프로그램에서 Spotify를 제어하고 있습니다. ScriptingBridge -> 속성에 할당 할 수 없습니다 : 'self'는 변경 불가능
spotify.soundVolume = 10
나는
cannot assign to property: 'self' is immutable
내가 잘못 뭐하는 거지 오류를 얻을 : 내가하려고 할 때 다음
var spotify: AnyObject = SBApplication(bundleIdentifier: "com.spotify.client")!
:
그래서 같은 응용 프로그램 개체를 만드는 오전 ? 나는 스포티 파이의 설명서에 따라 볼륨을 설정 할 수 있어야한다 :

'spotify.soundVolume = 10'은 어디에서 실행합니까? mutable (mutating func ...')으로 표시 할 필요가있을 때를 대비하여 _structure_ ('struct') 메소드에서이 시도 된 돌연변이를 수행하고있는 것 같습니다. – dfri
