Chapter 5: Coding Error Under "Creating a Cocoa Touch Class"

[ccocchiaro]

In Chapter 5 (page 97 of the Extreme Mobile PDF) under "Creating a Cocoa Touch Class", the code sample should reference the correct UserDefault (e.g. trackCount). The downloaded code itself is correct, only the book contains the oversight:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
        
    var trackCount = 1
        
    if let bundle = Bundle(identifier:"com.gw.RecordingStudioFW"),
            let path = bundle.path(forResource: "RecordingStudio", ofType: "plist"),
            let plistDict = NSDictionary(contentsOfFile: path),
            let tracks = plistDict.object(forKey: "trackCount") as? Int {
        trackCount = tracks
    }

    if let features = UserDefaults.standard.object(forKey: "iaps") as? [String: Any],
           let tracks = features["trackCount"] as? Int {
        trackCount = tracks
    }
