任务以错误结束-代码：-999在Mapbox上创建自定义用户位置注释时

Question

我installed mapbox into my xcode project using cocoapods。

然后，我刚刚将example for creating a custom user location annotation复制并粘贴到了我的视图控制器中。

我一遍又一遍地得到以下错误。

当我放大和缩小地图时，或者有时在我移动地图时，它们似乎会发生。

代码

仅有的快速文件是 ViewController.swift ，该文件是从mapbox website精确复制的

和 AppDelegate.swift ，它们是自动创建的（我已经从AppDelegate中删除了注释）。

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {return true}
    func applicationWillResignActive(_ application: UIApplication) {}
    func applicationDidEnterBackground(_ application: UIApplication) {}
    func applicationWillEnterForeground(_ application: UIApplication){}
    func applicationDidBecomeActive(_ application: UIApplication) {}
    func applicationWillTerminate(_ application: UIApplication) {}
}
