iOS Build a Selfie App with Swift 2 Adding Image Filters Rendering to GLKView

5 blank images without filters shown.

It seems no images are showing rather than the 5 smaller images that should be showing(7:30). The error occurs at this line i believe:

ciContext.draw(image, in: rect, from: image.extent)

It has been updated to swift 3 syntax but cant image it doing anything different from swift 2 in the video.

The output i receive is FaceSnap[5103:3985585] -[CIContext drawImage:inRect:fromRect:] requires a CIContext created with a GL context or a CG context!

Not sure where the problem is
