    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)
            
        }
