Xcode 6 does not create a new project or playground. It just stalls in the process

Problematic Workflow:

1. Start Xcode,

2. New ->Project,

3. Pick Single View Application ->next,

4. Enter app name etc ->next,

5. "Choose Options for your project:" page opens which does not let me do anything.

It just stalls there. There is "Add to" combo box in this page which is not responsive. SinceI can`t do any changes on this page I cannot click on "next" either, i.e., it is disabled.I can click on "previous" which turns back to project name etc page.

This started to happen all of a sudden yesterday. There is no crash or anything, just unresponsive screen. But I cannot do any development at all since I cannot create a project in the first place.

Finally the problem was solved. Steps were below: 1 - Update the system to Yosemite, 2 - Completely clean the system off of the Xcode (I did it using AppCleaner, freely available on the internet), 3 - Make sure no trace of Xcode exist in the system, 4 - Go to App Store and install Xcode from scratch.
