消除 Xcode7 中 directory not found for option xxxx 警告

升级Xcode7之后，你会遇到一些警告信息，诸如以下一条：

 ld: warning: directory not found for option -F/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/Developer/Library/Frameworks

ASK：

After upgrading an existing swift project I am seeing the following warning when it builds the tests:

 ld: warning: directory not found for option -F/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.0.sdk/Developer/Library/Frameworks 

That directory does not exist.. should it be looking for SDKs/iPhoneOS9.0.sdk/System/Library/Frameworks?

Is this something that needs fixing within my project files/build settings/etc?

ANSWER：

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.

Note: I have not exhaustively compared settings, so there may be additional differences.
