Remove space character from Objective-C directory

This might be viewed as a style preference, but highly recommend changing the Objective-C path for your project from:

MPGNotification/Objective C/

..to something that does not include spaces, such as:

MPGNotification/Objective-C/ (or similar)

Using a space is technically valid, but not using spaces (or other escaped characters) makes navigation via terminal (and URL!) much simpler.
