Provide a screen shot if you can.

This is the screen shot requested I hope you can help me.

These are what is known as invisible characters. They make no material difference to your code. They indicate where there are space characters and linefeed characters.

To turn them off, tap on the icon in the top right corner of your Xcode window, as indicated in the attached image, and then select Invisibles to toggle them off.
