ld: framework not found MicrosoftBandKit_iOS
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I just created the project, added the framework in build phases. the framework is clearly under the project. but it still says not found. i know that it may needs to finish framework search path. but i don't understand how to? like put in the absolute path for the framework?

no absolute path is bad way, it only work in your computer, not work with your partner. Set relative path is best way. To set path for framework:

be sure framework locate in project folder
select target -> Build Setting -> Search Path-> Framework Search Paths. Double click it will show an Search Paths input text view
in Finder go to folder content framework. Drag this folder to search paths input text view. it will be some thing like "$(SRCROOT)/Vendors/FacebookSDK"
just remove double qoute "", result: $(SRCROOT)/Vendors/FacebookSDK

done!
