Xcode 7 Library search path warning

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.

Based on the error message, it sounds like the first order of business is to get the target's path straightened out. You can edit the paths as shown in the answers to this StackOverflow question. Be sure to check the path for all your targets if you're not sure which is generating the error --- this threw me for a bit after upgrading a project to the Xcode 7 beta; there was a path in the FRAMEWORK_SEARCH_PATHS for the test target that needed to be deleted. The path that was in there was exactly the path you report getting the warning on; removing the path eliminated it.

King-Wizard is essentially correct, to elaborate a little more -

Xcode 7 is looking for your testing framework XCtest.framework in a path that does not exist. The path set by $(SDKROOT)/Developer/Library/Frameworks under 'Search Paths -> Framework Search Paths' is looking for the framework in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/Developer/Library/Frameworks which is not a valid path. You can delete the line $(SDKROOT)/Developer/Library/Frameworks to remove the error and still be able to run tests.

The correct path to 'XCTest.framework' is /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Frameworks for those that are curious.

I hope that helps.
