我正在关注Github 上的本教程以尝试学习如何使用 SwiftyDropbox,但我遇到了这个错误
import UIKit
import SwiftyDropbox
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate { //线程1:信号SIGABRT
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
DropboxClientsManager.setupWithAppKey("qcvovib4h1mn0zd")
return true
}
这是我在输出框中得到的

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.
}
}
我需要做什么来修复错误?
