I got this error when I tried to copy from a URL I couldn't copy. Which was coming from the <code>mediaURL</code> from the <code>UIImagePickerControllerDelegate</code>.
Basically, what I did was to use <code>UISaveVideoAtPathToSavedPhotosAlbum</code>
Like in this example ⤵️
<pre class="lang-swift prettyprint-override"><code>if UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(url.absoluteString) {
 UISaveVideoAtPathToSavedPhotosAlbum(url.absoluteString, self, #selector(self.didSaveVideo), nil)

@objc private func didSaveVideo(videoPath: String, error: NSError, contextInfo: Any) {}

blocks|key|526972|text|我也经历过同样的问题。我导入了AVKit而不是og+AVFoundation，并试图将视频显示在本机记录器视图中。这给了我一个异常，告诉我要将NSMicrophoneUsageDescription添加到info.plist文件中，之后，我能够在自定义视图中显示实时视频。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|526973|因此，我认为问题在于iOS+14对权限非常挑剔，而且当视频未在本地视图中显示时，显示正确的异常可能会出错。|526974|不管怎么说，这对我有用：|526975|import+AVKit

I experienced the same issue. I imported <code>AVKit</code> instead og <code>AVFoundation</code> and tried to present the video in the native recorder view. That gave me an exception telling me to add <code>NSMicrophoneUsageDescription</code> to the info.plist file, and after this, I was able to display the live video in a custom view.
So I believe the issue is with iOS 14 being very picky about permissions, and probably something goes wrong with showing the correct exception when the video is not presented in the native view.
Anyway, this worked for me:
<pre><code>import AVKit
import MobileCoreServices

@IBOutlet weak var videoViewContainer: UIView!

private let imagePickerController = UIImagePickerController()

override func viewDidLoad() {
 super.viewDidLoad()
 initCameraView()
}

func initCameraView() {
 // Device setup
 imagePickerController.delegate = self
 imagePickerController.sourceType = .camera
 imagePickerController.mediaTypes = [kUTTypeMovie as String]
 imagePickerController.cameraCaptureMode = .video
 imagePickerController.cameraDevice = .rear
 
 // UI setup
 addChild(imagePickerController)
 videoViewContainer.addSubview(imagePickerController.view)
 imagePickerController.view.frame = videoViewContainer.bounds
 imagePickerController.allowsEditing = false
 imagePickerController.showsCameraControls = false
 imagePickerController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
}
</code></pre>
And then the added description for the <code>NSMicrophoneUsageDescription</code> in the info.plist file :-)
Hope it will work for you as well!

I found the same error with Xcode 12 &amp; iOS 14 when imagePicker's source type is camera.
But the app is working fine, I could take picture using camera and put it in my collection view cell. Thus, maybe something on Xcode 12 I guess.
<pre><code> @objc func addPerson() {
 let picker = UIImagePickerController()
 if UIImagePickerController.isSourceTypeAvailable(.camera) {
 picker.sourceType = .camera
 } else {
 fatalError(&quot;Camera is not available, please use real device.&quot;)

 present(picker, animated: true)
 }

blocks|key|1406102|text|在我的例子中，我通过尝试使用图像数据和与Files同步，得到了这个bug。在Info.plist中添加此权限会产生所有差异，并使错误消失：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1406103|<key>LSSupportsOpeningDocumentsInPlace</key>+<true/>|1406104|entityMap^0|12|A|0|0|1G|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

in my case, I got this bug from trying to use the image data and syncing with Files. Adding this permission in <code>Info.plist</code> made all the difference and made that error go away:

I faced the same error with Xcode 12 &amp; iOS 14.
But in my case, I used ActionSheet to choose camera or photo library before that. So I changed to open camera just after close that ActionSheet, and it works well.
Hope this will be helpful on your issue.
<pre><code>

 func selectImage(mediaType: MediaOptions) {
 self.mediaOption = mediaType
 let iPicker = UIImagePickerController()
 iPicker.delegate = self

 if mediaType == .Camera {
 if UIImagePickerController.isSourceTypeAvailable(.camera) {
 iPicker.sourceType = .camera
 iPicker.allowsEditing = true
 }
 } else {
 iPicker.sourceType = .photoLibrary
 }
 self.present(iPicker, animated: true, completion: nil)
 self.imagePicker = iPicker
 }

 func choosePhoto() {
 let actionSheet = UIAlertController(title: &quot;Choose&quot;, message: &quot;&quot;, preferredStyle: .actionSheet)
 
 if UIImagePickerController.isSourceTypeAvailable(.camera) {
 actionSheet.addAction(UIAlertAction(title: &quot;Camera&quot;, style: .default, handler: { (action) -&gt; Void in
 actionSheet.dismiss(animated: true) {
 self.selectImage(mediaType: .Camera) // Just moved here - inside the dismiss callback

 }
 if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) {

In my case, I was missing an <code>Info.plist</code> key for <code>NSCameraUsageDescription</code>.
You should enter the purpose of using camera as the description.
It fixed the crash for me.
Plus, if you don't give the purpose, your app is likely to be rejected.

If you customize your image picker as <code>imagePicker.allowsEditing = true</code>
you have to fetch image using:
<pre><code>if let pickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
 capturedImage = pickedImage 
}
</code></pre>
If you instead use <code>imagePicker.allowsEditing = false</code>, use this to pick image:
<pre><code>if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
 capturedImage = pickedImage 
}
</code></pre>
If you don't follow this combination, you may get this error.

blocks|key|672483|text|我设法解决了这个问题。事实上，它与反应问题是，我使用的反应本机操作表，让用户可以选择打开相机或画廊。当我打开“反应本机操作表”并按下其中一个选项时，相机正在叠加产生冲突的“反应本机动作表”(模式)，因为显然在IOS中，一个模式不可能与另一个模式重叠。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|672484|因此，为了解决这个问题，我定义了一个超时，以便能够在打开相机之前关闭模式。|672485|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I managed to solve the problem. In fact, it is not directly related to react-native-image-crop-picker. The problem was that I was using react-native-actionsheet to give the user the option to open the camera or the gallery. When I opened the react-native-actionsheet and pressed one of the options, the camera was superimposing the react-native-actionsheet (modal) which generated a conflict, because apparently in IOS it is not possible for one Modal to overlap the other.
So, to solve the problem, I defined a timeout so that it is possible to close the modal before opening the camera.

blocks|key|527254|text|如果像我一样，你还有第二条信息：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|527255|[access]+This+app+has+crashed+because+it+attempted+to+access+privacy-sensitive+data+without+a+usage+description.++The+app's+Info.plist+must+contain+an+NSCameraUsageDescription+key+with+a+string+value+explaining+to+the+user+how+the+app+uses+this+data.|code-block|syntax|javascript|527256|然后，您必须将其添加到info.plist字典中：|527257|<key>NSCameraUsageDescription</key>

If like me you have this second message :
<pre><code>[access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.
</code></pre>
Then you have to add this to your info.plist dictionary:
<pre><code>&lt;key&gt;NSCameraUsageDescription&lt;/key&gt;
 &lt;string&gt;so you can choose a photo or take a picture for object detection&lt;/string&gt;
</code></pre>
It solved the problem for me
