How to know if your .ipa is 64-Bit

Question

I've built an .ipa file with following flags armv7 armv7s and arm64. Is there any way/ tool through which i can make sure the .ipa does have the 64-Bit support?

How does apple find out during app submission if the app binary does have 64-Bit support.

Answer 1

One of the options is to use lipo -info %path-to-executable% make sure you are not using path to .app folder or .ipa archive.
