Question

我跟随this tutorial on Github尝试学习如何使用SwiftyDropbox，但我遇到了这个错误

import UIKit
import SwiftyDropbox

@UIApplicationMain

class AppDelegate：UIResponder，UIApplicationDelegate {//主题1：信号SIGABRT

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        DropboxClientsManager.setupWithAppKey("qcvovib4h1mn0zd")
        return true
    }

这是我在输出框中获得的内容

这是我的ViewController代码

import UIKit
import SwiftyDropbox


class ViewController: UIViewController {
    @IBOutlet weak var launchDropbox: UIButton!

    @IBAction func launchDropboxPressed(_ sender: Any) {
        DropboxClientsManager.authorizeFromController(UIApplication.shared, controller: self,
                                                      openURL: { (url: URL) -> Void in
                                                        UIApplication.shared.openURL(url)
        })
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }



}

我需要做些什么才能解决错误？
