Xcframework issue #72

_When using an xcframework that depends on another framework, the X is not a member of type Y will also happen for the Framework it depends on when writing an extensions that wraps, for example, delegate methods

Example: Framework Foo depends on Bar and need to conform to DataDelegate.

class Foo {
    ...
}

extension Foo : Bar.DataDelegate {
    ...
}
Everything during compiling will go as planned and the xcframework will be generated. Once you add it to your App along with the dependancy framework Bar and try to build it you will get DataDelegate is not a member of type Bar._
