Really big iOS release

This is an old post, but with no solution so here's mine;

Go to Build Settings and check: Symlink Unity Libraries.

You'll find your build size folder drop down to normal levels.

I have the same problem where libiPhone-lib.a is way too big(321mb). Help will be kindly appreciate. :)

Thank you

I created empty project with Unity 5.3.4p1. Archived it in Xcode 7.3 and exported with distribution profile for App Store deployment and did following analysis.. IPA size was: 159MB (Unity-iPhone.ipa) Then I extracted it and got following folders: 18MB BCSymbolMaps (these are symbol files supporting Bitcode, won't be delivered to end user)
 243MB Payload (includes game assets, extra files and executable, which was 238M) 58MB Symbols (these are symbol files, won't be delivered to end user) Now I had to analyze Payload, which was mostly executable + standard engine assets. Since assets were only ~5 MB, I won't dig into that, but rather focus on executable. I analyzed it with otool, by running it twice: 1) otool -arch armv7 -l exec_name, 2) otool -arch arm64 -l exec_name. Then I checked included segment sizes: 1. armv7: 1. TEXT segment (code): 7.5 MB 2. DATA segment (various static fields for code and il2cpp metadata): 0.3 MB 3. LLVM (Bitcode) segment: 111.1 MB (will be stripped by Apple servers and won't be delivered to end users). 4. LINKEDIT (linking with dynamic libraries) segment: 0.9 MB 2. arm64: 1. TEXT segment (code): 8.4 MB 2. DATA segment (various static fields for code and il2cpp metadata): 0.5 MB 3. LLVM (Bitcode) segment: 110.2 MB (will be stripped by Apple servers and won't be delivered to end users). 4. LINKEDIT (linking with dynamic libraries) segment: 0.8 MB Exec size without Bitcode for armv7 is 8.7 MB and for arm64 it is 9.7 MB. Total exec size without Bitcode: 18.4 MB Estimated installation size (exec + assets): 23.4 MB Expected download size without app thinning : 1.25 MB (compressed assets) + 15.9 MB (TEXT segment, which doesn't compress well because of encryption) + 0.5 MB (DATA+LINKEDIT, they compress pretty well) = 17.65 MB
