一旦用戶的位置已經被迅速發現，使當前位置顯示在地圖上3

您好我正在嘗試修復這個功能，直到swift 3完全正常，有人知道這個改變是什麼嗎？一旦用戶的位置已經被迅速發現，使當前位置顯示在地圖上3

override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { 
    if !didFindMyLocation { 
     let myLocation: CLLocation = change?[NSKeyValueChangeKey] as! CLLocation //Getting an error here Cannot convert value of type '(NSKeyValueChangeKey).Type' (aka 'NSKeyValueChangeKey.Type') to expected argument type 'DictionaryIndex<_, _>' 
     viewMap.camera = GMSCameraPosition.camera(withTarget: myLocation.coordinate, zoom: 10.0) 
     viewMap.settings.myLocationButton = true 

     didFindMyLocation = false 
    } 

}

你應該提供適當的鍵象下面這樣：

let myLocation: CLLocation = change?[NSKeyValueChangeKey.newKey] as! CLLocation
