IL2CPP Build Error

jaclark · Sep 14, 2018

Hey all,

We get this build error when building for iOS. It's nondescript -- the only piece of information I have to go on is that it's an error with our render pipeline assembly.

IL2CPP error for type '<PrivateImplementationDetails>/$ArrayType=24' in assembly '/Users/jaclark_games/WhereCardsFall/Project/Temp/StagingArea/Data/Managed/com.unity.render-pipelines.wcfrp.Runtime.dll'
Additional information: Build a development build for more information. Exception has been thrown by the target of an invocation.

Weird part is that it seems to come up randomly. Our builds have been fine -- I changed one unrelated line of code (has nothing to do with that render pipeline assembly), and it started to happen, and won't go away.
The only other clue I have to go on is that I had just fixed a build-time error (editor code in packaged build, had just removed that code when this occurred.)
I'm building a development build, but it doesn't seem to recognize that and give more information.

We had this issue before -- I rearranged some of our assembly definition files and it seemed to fix it. However, it's back and I'm stuck again. :/

After looking around for a bit, this is probably more applicable to the Platforms -> iOS part of the forums. I've posted it there. (I'm not sure how to delete this thread)
