IL2CPP, 64-bit, Debug vs Release app size (Unity 4.6.7p3)

Hi,

I have noticed that when I run my project by selecting the release mode in Xcode, the app size increases substantially. So I go ahead and created an empty project, here are the results:

Debug Mode: 35 mb
Release Mode: 52 mb

Is that normal? I would expect release mode is always a bit smaller than debug mode (so says the official documentation)

Here are my settings:
Unity 4.6.7p3
Xcode 6.4
Scripting Backend: IL2CPP
Architecture: Universal
Target Device: iPhone + iPad
Graphics API: Automatic
Target iOS Version: 6.0

I think that was a hard question. Let me simplify:

a) This is the intended behaviour.
b) This is a known issue. We are on it.

a or b?

I think a.
Because, Release Mode is include 32bit and 64bit.
You see that the number of files during the build is in the double.

Ok, thanks for the clarification.

An compiling takes ages at least on my old Mac…
