Ошибки при реализации сторонней библиотеки в проекте Xcode

Question

Я пытаюсь использовать стороннюю библиотеку TTFortuneWheel для создания приложения. Следующий код - это то, что я добавил в этот новый проект.
Когда я запускаю приложение, оно показывает эту ошибку: EXC_BAD_ACCESS (код = 2, адрес = 0x10e5c8dd8)

class ViewController: UIViewController {


    @IBOutlet weak var spinningWheel: TTFortuneWheel!

    override func viewDidLoad() {
        super.viewDidLoad()

        let slices = [ FortuneWheelSlice(title: "Slice 1"),
                       FortuneWheelSlice(title: "Slice 2"),
                       FortuneWheelSlice(title: "Slice 3")]

        let frame = spinningWheel.frame
        let fortuneWheel = TTFortuneWheel(frame: frame, slices: slices)
        spinningWheel.equalSlices = true
        self.view.addSubview(fortuneWheel)

Я также пыталсяследующий код, который изменен из образца TTFortuneWheel и успешно запущен в образце проекта, но он показывает другую ошибку при запуске в моем проекте: EXC_BAD_ACCESS (code = EXC_I386_GPFLT)

 let slices = [ FortuneWheelSlice.init(title: "Roller Coaster"),
                       FortuneWheelSlice.init(title: "Try again"),
                       FortuneWheelSlice.init(title: "Free\nticket"),
                       FortuneWheelSlice.init(title: "Teddy\nbear"),
                       FortuneWheelSlice.init(title: "Large popcorn"),
                       FortuneWheelSlice.init(title: "Balloon figures"),
                       FortuneWheelSlice.init(title: "Ferris Wheel"),
                       FortuneWheelSlice.init(title: "Pony\nRide")]
        spinningWheel.slices = slices
        spinningWheel.equalSlices = true
        spinningWheel.frameStroke.width = 0
        spinningWheel.slices.enumerated().forEach { (pair) in
            let slice = pair.element as! FortuneWheelSlice
            let offset = pair.offset
            switch offset % 4 {
            case 0: slice.style = .dark
            case 1: slice.style = .light
            case 2: slice.style = .dark
            case 3: slice.style = .light
            default: slice.style = .dark
            }
        }

Я попытался решитьЭти проблемы в течение недели и читать через все файлы TTFortuneWheel. Буду признателен, если кто-нибудь поможет мне решить эти ошибки или поможет правильно использовать TTFortuneWheel!
