This is how I fixed this problem
Further to a migration of my Xcode project, from Xcode 6.4 to Xcode 7, I get the warning message below (after compilation) for the Test target :
directory not found for option '-F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator9.0.sdk/Developer/Library/Frameworks'
Actually I found something when comparing a new project vs an older one...
In the old project, the warning was only being produced by the test target of my projects. Under 'Search Paths', I found it was including two items under 'Framework Search Paths':
$(SDKROOT)/Developer/Library/Frameworks
$(inherited)
The new project kept the 'Framework Search Paths' empty.
Deleting those entries in my older project then removed the warning.
Notes:
I have not exhaustively compared settings, so there may be additional differences.
Also, just in case if one day you re-encounter one of the two following warning messages, just remember that you will have to do that: if the warning is for option '-L/...'
that is Library Search Paths, delete the stuff there. However if the warning is for option '-F/...'
that is Framework Search Paths, delete the stuff there.
