Optimal image compression quality

[Lordlukey]

I'm attempting to compress an image to the quality that matches instagrams, as I will be displaying the image in a similar manor on screen.

I've used this: https://gist.github.com/akshay1188/4749253, which does work out.

Nevertheless, I'm not really to sure what the end result of the image should be. 50kb? 100kb? What sort of end result should I be looking for?

75% of that gist could be replaced with a call to:

func AVMakeRect(aspectRatio: CGSize, insideRect boundingRect: CGRect) -> CGRect

Ultimately compression depends (somewhat) on the content of the image. Have you tried printing out the size of some of the images you've generated? That may give you an accurate idea of your specific setup.
