Swift 3 performances

Hi all.

almost all of our apps has been updated to be compiled by XCode 8.3.2. We're using Swift3 and we noticed that on 32bit older iphone5/5C there are a drop down about performances. Application freezes for a while (about 1 or 2 seconds) and after this time we get rendering problem on some UI elements. Pull up/down, swipe, pull to refresh are not fluid. Same ipa running on 5s or later does not have any freeze problem nor rendering.

Any idea? Anyone else is facing same problems?

Are you sure it's your app doing this? 32 bit devices are very freezy under iOS 10.3 in general. My iPad 4 freezes up for 10 seconds at a time quite often now, never did that before.
