Hi All,

Sometime we have to take a picture using camera and use that image , we have to follow these simple steps.

1) Ask permission to access camera and microphone. Add these key and value in your project plist:-

<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>

2) Add code to open camera to take picture :-

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera){
            
            let imag = UIImagePickerController()
            
            imag.delegate = self
            imag.sourceType = UIImagePickerControllerSourceType.camera;
            imag.allowsEditing = true
            imag.mediaTypes = [kUTTypeImage as String]
            self.present(imag, animated: true, completion: nil)
        }

3) Last step to use clicked image by user :-

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        print(info)
//you can use image in data variable as this image is one which user picked from gallery. 
         let data = UIImagePNGRepresentation(info[UIImagePickerControllerEditedImage] as! UIImage)
        
    }
