I have the following code in my app to make all of my AVPlayers play audio in the background as well as foreground. It worked fine in Swift 4.

        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, with: .mixWithOthers)
            NSLog("Playback OK")
            try AVAudioSession.sharedInstance().setActive(true)
            NSLog("Session is Active")
        } catch {
            NSLog("ERROR: CANNOT PLAY MUSIC IN BACKGROUND. Message from code: \"\(error)\"")
        }

Then this morning when I converted to Swift 5, I'm now getting an error on line 02 that says "Ambiguous reference to member 'setCategory'". What does this mean and how can I fix it?

            NSLog("Playback OK")
            try AVAudioSession.sharedInstance().setActive(true)
            NSLog("Session is Active")
        } catch {
            NSLog("ERROR: CANNOT PLAY MUSIC IN BACKGROUND. Message from code: \"\(error)\"")
        }
