Any idea why my app size goes from
18mb on Android to
55mb on IOS
I haven’t changed anything just switched the build target and built the xcode project…
Seems a bit extreme to me?
Typically you will have an armv6 and armv7 build, which will add a lot of overhead. Doesn’t explain the whole scenario, but it adds a good 10 - 15mb.
Try building for arm6 only (it will give you a warning about needing arm7, but you can get approved with arm6 only).
Unity Android uses JIT (just in time compilation) - managed code is compiled to native on first access at run time.
Unity iOS uses AOT (ahead of time compilation) - all the managed code is precompiled when building app.
1 MB of managed code ~ 3 MB of ARM code.
