カメラまたはPhotoLibraryをUIImagePickerControllerでロードしますか？

私は最近、iOS 10のSwift 3で写真を撮るか、画像を選択するコードを入れました。開いているカメラまたは写真ライブラリのいずれかを呼び出すと、アプリは「スレッド14：シグナルSIGABRT」でクラッシュします起こっていることの表示。私にとって、また私がデバッグしたものから、ネイティブのカメラビューや写真ライブラリをロードしようとしているときにこれが起こります。どんな助けでも大歓迎です！カメラまたはPhotoLibraryをUIImagePickerControllerでロードしますか？

以下のコード：あなたはこのlinkをチェック以降のiOS 10から今

<key>NSPhotoLibraryUsageDescription</key> 
<string>Use Photos</string>

をInfo.plistファイルにキーを追加する必要が

class CameraViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    super.viewDidLoad()

@IBAction func BTN_takePhoto(_ sender: AnyObject) { 

    print("button pressed") 

    if (UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)){ 

     print("source available")
