Micro mscorlib working with Android builds but not iOS builds

When compiling our project under Android using the micro mscorlib optimization, the game compiles just fine. When switching over to iOS and attempting to build, this exception is raised:

Code (csharp):

1. UnityException: Failed assemblies stripper: /Applications/Unity/Unity.app/Contents/Frameworks/Mono/bin/mono "/Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper/UnusedBytecodeStripper.exe" -l none -c link -a "Assembly-CSharp-firstpass.dll" -a "Assembly-CSharp.dll" -a "Assembly-UnityScript.dll" -out output -x "/Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper/link.xml" -d "Temp/StagingArea/Data/Managed" -x "/Users/spencerelliot/BossRace/Assets/link.xml" -x "tmplink.xml" current dir : Temp/StagingArea/Data/Managed

7. UnityEditor.MonoAssemblyStripping.MonoLink (BuildTarget buildTarget, System.String managedLibrariesDirectory, System.String[] input, System.String[] allAssemblies, UnityEditor.RuntimeClassRegistry usedClasses)
8. UnityEditor.HostView:OnGUI()

I've attempted to keep various classes in using the link.xml file and it has allowed the compiler to get further but it won't find the System.Security.Policy.Evidence class no matter what I put in. This is my link.xml file:

Code (csharp):

1. <linker>
2.     <assembly fullname="System">
3.         <type fullname="System.*" preserve="all"/>
4.     </assembly>
5.  
6.     <assembly fullname="System.Security">
7.         <type fullname="System.Security.*" preserve="all"/>
8.     </assembly>
9.  
10.     <assembly fullname="Mono.Security">
11.         <type fullname="Mono.Security.*" preserve="all"/>
12.     </assembly>
13.  
14.     <assembly fullname="mscorlib">
15.         <namespace fullname="System.*" preserve="all"/>
16.         <namespace fullname="System.Runtime.*" preserve="all"/>
17.         <namespace fullname="System.Security.*" preserve="all"/>
18.         <namespace fullname="System.Security.Policy.*" preserve="all"/>
19.         <namespace fullname="System.Security.Cryptography.*" preserve="all"/>
20.     </assembly>
21. </linker>

Any help is greatly appreciated, thanks.

 

Did you find a solution? I'm currently struggling with the exact same problem.

 

Do you use HOTween? My guess is that you use a plugin that cannot be compiled in mscorlib with iOS, just like HOTween's stock release
