Xcode: LLVM 7.0: Disable warning "Umbrella header for module does not include header"
If you're getting this warning from a “Compile Swift source files” ▸ “Precompile bridging header” build step (also labeled PrecompileSwiftBridgingHeader), here's how you suppress it:
- Find the Build Settings for your project.
- Search for “Other Swift Flags”.
- Add
-Xccand-Wno-incomplete-umbrellato “Other Swift Flags” (in that order).
Try setting the header role from public to project and make sure that you don't reference any third-party headers from your own headers - only from implementations.
Any header that is of role public must be imported into the umbrella header.
