Is it available in Swift?

I can't find examples of CIDetector with Live Video anywhere.

Any toughts?

Hi! Thank you so much for this piece of code, its really nice!

I have just some doubts, can you please help me?

1 - To change the border.png image dinamically / programatically, what should I do?

Im doing right now:

[self setupAVCapture];
self.borderImage = [UIImage imageNamed:@"newImg.png"];
NSDictionary *detectorOptions = [[NSDictionary alloc] initWithObjectsAndKeys:CIDetectorAccuracyLow, CIDetectorAccuracy, nil];
self.faceDetector = [CIDetector detectorOfType:CIDetectorTypeFace context:nil options:detectorOptions];

This is the correct/best way to change it dinamically?!? I'm getting memory warning sometimes.

2 - I'm trying to save the current view as an image with this code:

if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)]) {
    if ([[UIScreen mainScreen] scale] == 2.0) {
        UIGraphicsBeginImageContextWithOptions(self.previewView.bounds.size, YES, 2.0);
    } else {
        UIGraphicsBeginImageContext(self.previewView.bounds.size);
    }
} else {
    UIGraphicsBeginImageContext(self.previewView.bounds.size);
}

[self.previewView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

UIImageWriteToSavedPhotosAlbum(viewImage, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);

I just want to save a image of the whole thing that is displaying on the screen, the "live camera" plus the overlay image.

But with this code, I'm getting a completely black image as output.

Can you help me with this? Thank you so much :)
