I think Dinesy is right. This solves the problem for me.
I've noticed that Xcode7 doesn't automatically fill in the required
Framework search paths when you import a 3rd party one (I believe
Xcode6 did do this). Check if yours are empty by going to Project ->
Build Settings -> Search Paths -> Framework Search Paths. Fill it in
with wherever your Frameworks live. If it's under your project you can
use $(PROJECT_DIR)
