iOS 10.1 warning while launching the application

Question

Why application is getting this alert and how to solve this -

"AppName" may slow down your iPhone The developer of this app needs to update it to improve its compatibility.'

I have gone through this link: iOS 10.1 Simulator shows "Application May Slow Down Your iPhone" From, the above link i tried to set "BUILD ACTIVE ARCHITECTURE = NO", but it did not worked.

Please help me to solve the issue.

Answer 1

This message appears because your app builds only for 32 bit architecture.

You need to add the 64 - bit architecture in your project's build settings. Just add $(ARCHS_STANDARD) in Architectures field and arm64 in Valid architectures field.

This is also required for apps uploaded to the App Store. Without 64-bit your app will be rejected.
