iOS app size vastly larger than Android

I’ve built and released my game on Android, the apk size is only 28MB. I did a build for iOS, first using IL2CPP and building for both Architectures … this resulted in an IPA size of 171MB! At first I thought it was because the build was IL2CPP and has both ARMv7 and ARM64 … however I’ve just done a mono build and the size is 156MB.

The editor log after doing a mono build shows:

How does it jump from 44MB to 156MB? Why is it so large? And how do I get it down to something more acceptable?

Edit: Using Unity 5.0.1f1 , and the same plugins between platforms.

Nevermind, I believe it’s because, for Android, I’m using the GooglePlayGames Unity Plugin, and adding this (unwanted) framework to iOS adds a 139MB file.

Edit: Removing that has now taken it down to 31MB, app submitted!

same problem.
Pls show me what did you do.
