I\'ve created a framework in which is inserted the second framework, the so-called \"umbrella framework\". When I insert the framework in the test application(embedded binar
I was able to set up a working Umbrella Framework and wrote down my approach.
Step 5 should remove your linker error ld: framework not found ..
A Swift based "client" project that has the Umbrella Framework as dependency
A dynamic Framework (mainly C++ and ObjC) that is a dependency of the Umbrella Framework

2. Add the location of the dependent (sub-)framework to the Framework Search Paths of the Umbrella Framework project.
3. In the "client" project make sure to link and embed the Umbrella Framework
4. Make sure the Umbrella Framework is copied into the (client-) app bundle to avoid dyld: Library not loaded: @rpath/... errors.
The (client-) app, usually under ...Build/Products/Debug-iphoneos/YOUR_CLIENT_APP.app should now contain your Umbrella Framework in a folder called Frameworks.
5. In the "client" project Make sure to add the path to the Umbrella Framework to Framework Search Paths.
If the ld: framework not found '[Framework_Name]' for
architecture ... error persists you can also add the path to the (sub-) Framework here.
