Updated to latest XCode 9 beta and found a couple of issues

[enzyme69]

Revision: if let points = landmark?.normalizedPoints, let count = landmark?.pointCount {

But getting more errors:
Cannot convert value of type '[CGPoint]' to expected argument type 'UnsafePointer<vector_float2>' (aka 'UnsafePointer')

Did you resolve the problem? If yes, can you share or commit your method?

Replace the convertPointsForFace with below, and it will work.

func convertPointsForFace(_ landmark: VNFaceLandmarkRegion2D?, _ boundingBox: CGRect) {
        if let points = landmark?.normalizedPoints {
            let faceLandmarkPoints = points.map { (point: CGPoint) -> (x: CGFloat, y: CGFloat) in
                let pointX = point.x * boundingBox.width + boundingBox.origin.x
                let pointY = point.y * boundingBox.height + boundingBox.origin.y
                
                return (x: pointX, y: pointY)
            }
            
            DispatchQueue.main.async {
                self.draw(points: faceLandmarkPoints)
            }
        }
    }

Thanks for your sharing!

Im still getting this with the new function:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-
[VNFaceLandmarkRegion2D normalizedPoints]: unrecognized selector sent to instance

Any ideas?
