消除directory not found for option '-F'/'-L' 警告

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.
