[swift-users] libswift frontend ios

[Ramakrishna Mallireddy]

If I remove ClangImporter related code in swift front-end, I am able to
start the app. so just want to know what features I miss without
ClangImporter. I want to emit LLVM IR assembly for pure swift code. ObjC/C
is not something I want to deal with right now.

Inputs on any unexpected things I might face going forward without
ClangImporter in this regard will greatly helpful.


Thanks
Ramakrishna
