We have been using the MASShorthandAdditions in the past. And now when we begin to use the new building system of Xcode there appeared about 20000 warnings which may block the normal progress of Xcode. Every time we run our project in Xcode about 10 minutes will be taken to wait for the normal state that can give a response as wish in time. So I separate the code into two files to avoid this problem. Knowing some others also met the situation when reading issues this change may help more people.
