Dear benbahrenburg,

I am also facing memory issues with compression I am reducing the size of the image first and then getting data with UIImageJPEGRepresentation applying metadata on this data cgimage properities. I am doing this using OpeationQueue for each operation does this job and upload to the server.Some times memory is going 400 to 500 MB. But the same code is working perfectly in Objective C .Can you tell me what can be my issue?
