Start the viewController with front cam

[vishalvshekkar]

Hey,

This is a wonderful library, thank you for this.

I have problem. I want to start my camera view controller with the front camera. If I invoke switchCamera() in viewDidLoad or viewWillAppear:animated, the app crashes with the following message:

[AVCaptureSession stopRunning] stopRunning may not be called between calls to beginConfiguration and commitConfiguration

I assumed that switchCamera() stopped the session when it was still being configured.

Then , I tried to set the currentCamera property to .front, but, that property's setter is private.

Am I missing a way to do this?

Hey vishal,

You will not be able to call switchCamera() in viewDidLoad or viewWillAppear:animated. The AVCaptureSession is configured asynchronously in viewDidAppear, so it fail until it has finished configuring.

Currently, there is no way to configure SwiftyCam the way you are asking. I had not considered to add an option for the default. It is something I will add very soon in a future release.

In the meantime, if you need this functionality, you can manually add the source code in the project. on line 143 of SwiftyCamViewController, change the currentCamera to front:

private(set) public var currentCamera        = CameraSelection.front

Should do the trick in the meantime. Ill update this issue once I add the functionality.

I have updated the project to support this functionality. You should update your project to version 2.1.0. Then in your ViewDidLoad, change the defaultCamera property to .front:

override func viewDidLoad() {
   super.viewDidLoad()
   defaultCamera = .front
   ...
}

This should do the trick. Let me know if you have any other issues

Hey, thank you for this quick enhancement.

I had done some makeshift changes to make it work with the front cam by default, but, I'm going to pull your changes from v 2.1.0 now.

Have a good one.
