Why does my app lag so much between swiping through videos and photos for example? Is the APIs or is it the AWS?

When I swipe through different screens on app it has horrible lag and or act as if it’s loading the content from screen to screen, how come? Is it the API’s or is it AWS?

Sounds like a job for Instruments. This sort of scenario sounds exactly like the kinds of sample apps they use in WWDC sessions about Instruments, so if you're not familiar with it, I recommend you watch of the Instruments session videos from the last year or two.

Building on QuincyMorris' response, use Instruments to profile the CPU usage of you app as a starting point.
