Camera Only Takes Pictures in Portrait Mode Swift

Swift UI camera shows portrait view but image turns out landscape

It returns only on landscape because the image which was taken with in-app camera has an orientation. You need to normalize it and display it.

I make an extension of UIImage with

func fixOrientation(img:UIImage) -> UIImage {

  if (img.imageOrientation == UIImageOrientation.Up) { 
      return img;
  }

  UIGraphicsBeginImageContextWithOptions(img.size, false, img.scale);
  let rect = CGRect(x: 0, y: 0, width: img.size.width, height: img.size.height)
  img.drawInRect(rect)

  let normalizedImage : UIImage = UIGraphicsGetImageFromCurrentImageContext()
  UIGraphicsEndImageContext();
  return normalizedImage;

}

Original answer from here:
Normalize Pictures taken by camera

Also I just did a few changes to copy and paste solution for the ImagePickerManager:

Camera just works in Portrait mode

You should set your AVCaptureSession orientation every time device's orientation is changed.

Add a Notification observer to observe any change in device orientation then set AVCaptureSession orientation according to device orientation.

Obj-C:

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(orientationChanged)
                                             name:UIDeviceOrientationDidChangeNotification
                                           object:nil];
-(void) orientationChanged
{
    if (self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
        [_previewLayer.connection setVideoOrientation:AVCaptureVideoOrientationPortraitUpsideDown];

    if (self.interfaceOrientation == UIInterfaceOrientationPortrait)
        [_previewLayer.connection setVideoOrientation:AVCaptureVideoOrientationPortrait];

    if (self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
        [_previewLayer.connection setVideoOrientation:AVCaptureVideoOrientationLandscapeLeft];

    if (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight)
        [_previewLayer.connection setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
}

Swift 2:

Add observer somewhere, for example in viewDidLoad method.

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(orientationChanged), name: UIDeviceOrientationDidChangeNotification, object: nil)

Then:

func orientationChanged(){
    let deviceOrientation = UIDevice.currentDevice().orientation

    if deviceOrientation == UIDeviceOrientation.PortraitUpsideDown {
        previewLayer.connection.videoOrientation = AVCaptureVideoOrientation.PortraitUpsideDown
    }
    else if deviceOrientation == UIDeviceOrientation.Portrait {
        previewLayer.connection.videoOrientation = AVCaptureVideoOrientation.Portrait
    }
    else if deviceOrientation == UIDeviceOrientation.LandscapeLeft {
        previewLayer.connection.videoOrientation = AVCaptureVideoOrientation.LandscapeLeft
    }
    else if deviceOrientation == UIDeviceOrientation.LandscapeRight {
        previewLayer.connection.videoOrientation = AVCaptureVideoOrientation.LandscapeRight
    }
}
