no umbrella header found for target, module map will not be generated

Question

When I trying build CKCountdownButton as a framework in Xcode 6.3, it complains with

warning: no umbrella header found for target 'CKCountdownButton', module map will not be generated

Then when I import this framework in other project, it failed with No such module 'CKCountdownButton'

Answer 1

I found another solution, Xcode provides a way to specify umbrella header through Module Map File configuration.

The contents of module.modulemap should be:

framework module Foo {     umbrella header "Bar.h"      header "other-header.h"      export *     module * { export * } }
