I'm building up a process for deploying to iOS 11 beta from Unity, using the latest XCode 9 Beta. I've followed the official guides, and everything goes fine until I get to compiling in XCode.
Whenever I start a compile it hangs forever at 'compiling asset catalogs'. This is despite using Unity's Simple Mobile Placeholder project, which has very few assets.
I've tried all the common solutions: from restarting XCode, to cleaning the build folder, all the way up to rebooting the computer.
Does anyone know of a fix, or at least a workaround for this issue? Unfortunately I cannot downgrade XCode because I need its new features for the project I am working on.
