Have you fixed this problem you asked? I meet this problem on today too, and I've fixed it just a moment. If you don't have fixed this problem, you can try the below steps:

p.s.: the 2 projects are in the same workspace (the static lib project and the App project), the static lib project is build before the app project. The workspace structure as the pic shows:

  1. In the static lib project, all the .h files are need add to "Build Phases/Copy Files":

  1. Drag the static lib product file (the .a file) to the app project, see the pic:

(path: "app project/Build Phases/Link Binary With Libraries")

enter image description here

*if you care about the red color mark for the .a file, you just need choose the "generic iOS device" as the build device to re-build the static lib project, and re-drag the .a to the app project(the red one can be delete)

  1. Set the "Library Search Path" in you app project:

enter image description here

this is the .a file path which the project built in: $(USER_LIBRARY_DIR)/Developer/Xcode/DerivedData/StockApp-fkjqyvsniiauxogkivalcduqeotj/Build/Products/Debug-iphoneos

  1. Create Bridging-Header file for your app project, and import the static lib in it, in my case I include "StaticLib/StaticLib.h" and "CommonFoundation/CommonFoundation.h":

enter image description here

  1. Add the Bridging-Header file path to "Objective-C Bridging Header" of you app project:

enter image description here

Then all done, you can use the functions of the static libraries now. enter image description here
