Bad access using didCaptureVideoSampleBuffer

[Cris Di Sclafani]

Hello,
if i try to handle the recorded time using didCaptureVideoSampleBuffer i get (after 2-3 seconds from start recording) a "EXC_BAD_ACCESS" error on

[self _enqueueBlockOnMainQueue:^{ if ([_delegate respondsToSelector:@selector(vision:didCaptureVideoSampleBuffer:)]) { [_delegate vision:self didCaptureVideoSampleBuffer:bufferToWrite]; } }];

I use swift and, if i don't add the didCaptureVideoSample it runs fine.
The problem is that i need to see the recorded time using a progress indicator.
Can anyone help me?
Thanks in advance !
Greetings
