Swift Framework: Umbrella header '[…].h' not found

Question

In a custom framework containing both Objective-C and Swift code, the Swift compiler throws the following error:

[build_pat         


        

Answer 1

There's 4 different ways this can happen, ignoring bugs in previous versions of Xcode

• You don't have a umbrella header named $(TARGET_NAME).h in your project
• You have a umbrella header, but it's not set as public. See arturgrigor's answer
• DEFINES_MODULE is not set to YES
• CLANG_ENABLE_MODULES is not set to YES
