Summary: Xcode 5-DP appears to have a hidden default header search path of $(SRCROOT). This can cause Xcode to #import incorrect header files if a subdirectory and root directory have headers with the same file name, even if the one in the root directory is not in the project. 

Steps to Reproduce:
1. Create a new Empty View application.
2. Create a custom NSObject class in a subfolder of your project called Foo. Make sure Foo.m is in your app target.
3. Copy the empty Foo.h/.m to the root folder of your project (where the AppDelegate, main.m etc are located). Do not add the copied empty Foo files to the project. Make sure to remove the ' copy' added to the file name.
3. Open the original Foo class file in Xcode and add a method, -(void)bar
4. In the ViewController.m, #import "Foo.h", in viewDidLoad, alloc/init a Foo, then call -bar.
5. Try to build.

Expected Results:
Project should build.

Actual Results:
Project fails to build because "no visible @inteface of Foo declares selector bar". Note that if you call performSelector:@selector(bar), you still get a warning about an undeclared selector, but bar will be called when run. 

Regression: Regression from Xcode 4.6

Notes: No workaround. Sample project attached.
