I am trying to write a iOS Cocoa Touch framework in swift and trying to use some old Objective C static libraries.

I am unable to use any of the header files from static library. It says "Use of undeclared type enter image description here"

I have gone through couple of threads in stack overflow before posting this thread. 1) Tried adding birding file - it complains that birding files are not supported in frameworks 2) Tried making the headers as public instead of project 3) Tried "allow_non_modular_includes_in_framework_modules"

Not sure what is that i am missing..

Thanks for the help.

  • Can you provide some basic information? For example if the bridging file caused error, what is the error message? What do you mean by point 2? Any screen shot? Commented Oct 19, 2014 at 2:23
  • The error says "Use of undeclared type SQLEngine. Swift file is unable to recognize the header file which came along with objective c static library. This issue is fixed now, Mistake I did is that i have not imported the header in umbrella file and trying to create Bridging Header, Later I learned that We cannot create birding headers inside Swift Frameworks.

Found the fix, Need to import the Header in umbrella file. Then Xcode is able to build without errors
