I’ve had this issue twice in the past few weeks, with a project that has lots of plug-ins with weird XCode issues. When it happens, it means lots of stuff can break and I have to delicately figure those issues all over again.
I have not changed anything in the project in Xcode, and have been only doing minor script fixes in Unity. If this happens, why can’t Unity tell us EXACTLY what the problem is, so I can not freaking do it again, or I can fix it?
My project does not have multiple targets and Xcode is definitely the same version as it has been, so what could I possibly have done to piss off Unity so that it refuses to append to my Xcode project?
