How to unlock swift file (Xcode)?

Question

When I try to write something in the assisted editor in Xcode 7.1, there's a error message that I can't change the code (can't unlock it), because I don't own it! Do you know how to let me have access to it?

Answer 1

I solved my problem by doing this

1. Go up to the folder containing the project in your Finder.

2. Right Click > Get Info

3. Go to the bottom of the Info pane, and click the little lock, type in your password when prompted.

4. Then, change permissions for yourself to read+write.

5. Click the little gear below, and apply to all enclosed items.

Close the lock once you are finished!
