How can I enforce a compiler warning or error for namespace conflicts?
I don't think at this point Xcode supports this unfortunately - some less fruitful solutions:
- Open a radar task, and hope that Apple fixes it.
- Prefix your classes (as we used to do with Obj-C)
The second option should be viable for most projects; instead of Foo and Foo, you will have LIBAFoo, LIBBFoo, but in practice, with more meaningful prefixes i.e. CA → Core Animation.
