Alert from os: app may slow down your iPhone

Question

Hy,

I have uploaded the app to App Store with both architecture. Please see the attached image for Build Settings of TARGETS in Archi

Answer 1

The problem is that Build Active Architecture Only, as shown in your screen shot, is set to Yes. This means that you are not building an app that contains both 32-bit and 64-bit architectures; you are only building for one architecture. And from what you say, that architecture must have been the 32-bit architecture.
