Ich verwende Scripting Bridge, um Spotify von meiner OSX-Anwendung aus zu steuern.ScriptingBridge -> kann der Eigenschaft nicht zuweisen: 'self' ist unveränderbar
Ich erstelle ein Anwendungsobjekt, wie so:
var spotify: AnyObject = SBApplication(bundleIdentifier: "com.spotify.client")!
dann, wenn ich versuche zu tun:
spotify.soundVolume = 10
Ich erhalte den Fehler
cannot assign to property: 'self' is immutable
Was mache ich falsch ? Ich sollte die Lautstärke nach Spotify in der Dokumentation setzen können: https://developer.spotify.com/applescript-api/
/*

SpotifyEPlSPaused = 'kPSp'
};

Zeigen Sie Ihren Swift-Code. – Alexander

Wo führst du 'spotify.soundVolume = 10' aus? Sehr wahrscheinlich führen Sie diese versuchte Mutation in einer Methode von _structure_ ('struct') durch, falls Sie diese Methode als' muting' ('mutating func ...') markieren müssen. – dfri
