The project works fine in Android and me facing the following issues while making iOS build

  1. Failed running /Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper2/UnusedBytecodeStripper2.exe -out “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed” -l none -c link -x “/Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper/native_link.xml” -f “/Applications/Unity/Unity.app/Contents/Frameworks/il2cpp/LinkerDescriptors” -x “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/…/platform_native_link.xml” -x “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/methods_pointedto_by_uievents.xml” -x “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Assets/link.xml” -d “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/Assembly-CSharp-firstpass.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/Assembly-CSharp.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/Assembly-UnityScript-firstpass.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/Assembly-UnityScript.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/UnityEngine.UI.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/P31RestKit.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/Photon3Unity3D.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/PlayerIOUnity3DClient.dll” -a “/Volumes/Data Backup/Nitish Project’s/EightBalls_client_Build/Temp/StagingArea/Data/Managed/App42-Unity3D-SDK-4.1.2.dll”

  1. Error building Player: Exception: /Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper2/UnusedBytecodeStripper2.exe did not run properly!

It looks like this is the error that matters:

Error processing method: ‘System.Void com.shephertz.app42.paas.sdk.csharp.connection.RESTConnectorWWW::ExecuteMultipart(System.String,System.String,System.Collections.Generic.Dictionary2 ,System.Collections.Generic.Dictionary2,System.Collections.Generic.Dictionary2 ,System.Collections.Generic.Dictionary2,System.String,System.String,com.shephertz.app42.paas.sdk.csharp.App42CallBack)’ in assembly: ‘App42-Unity3D-SDK-4.1.2.dll’ —> Mono.Cecil.ResolutionException: Failed to resolve System.Collections.Generic.Dictionary`2 UnityEngine.WWWForm::get_headers()

I’m not too familiar with the UnityEngine.WWWForm class, but it seems that ExecuteMultipart is trying to reference a method named get_headers, which does not exist.

Is App42-Unity3D-SDK-4.1.2.dll built against the same version of Unity that you are using? I suspect there may be a mismatch here.
