How to check if AVCaptureSession preset resolution is supported in Swift

Question

For instance, I may want to set it to hd1280x720, but only if it's supported, and use a lower res that is supported otherwise.

session = AVCaptureSession()
if(**my device supports hd1280x720**){
  session!.sessionPreset = AVCaptureSession.Preset.hd1280x720
}else if(**my device supports 640x480**){
  session!.sessionPreset = AVCaptureSession.Preset.vga640x480
}

What about https://developer.apple.com/documentation/avfoundation/avcapturesession/1389824-cansetsessionpreset ? — Martin R, Feb 24 '18 at 16:56

Use AVCaptureSession.canSetSessionPreset(_:):

Returns a Boolean value that indicates whether the receiver can use the given preset.

This always returns true. Any other way? – unobatbayar Jan 31 '23 at 06:33
