You can lock/unlock file easily by using the lock button (see below) in the text editor's navigation bar. See the XCode Workspace Guide for details.

solution, thats small mistake,

heres a solution, this may help some beginer like me,

if u need to protect your file from editing, you can select that file , and click the lock icon, that will be appear above split window icon, in xcode,(right edge). so that u cannot make changes on that file, if u need to unlock, just click once again.

thats it,
