When creating a custom framework that contains both Swift and Objective-C code, the compilation will fail if 'Always Search User Paths' is turned on.

Steps to Reproduce:
1. Create a new project and select 'Cocoa Touch Framework' as the type. Choose Objective-C as the language.

2. Add an empty Swift file

3. Go to the target build settings and set 'Always Search User Paths' to Yes

4. Press Product->Clean

5. Build the Framework

Expected Results:
The framework should successfully build, like it does when 'Always Search User Paths' is set to No

Actual Results:
There is a Swift Compiler Error:
