Iphone+Xcode+Badge "A" or "M" resembles what?
In Xcode, in the navigation area on the left, next to a few files, on the right there is a little icon badge, M or sometimes A.
What is that for?
Is there any option that I left selected while creating New Project or are any project settings responsible for this?
this responds to your git/svn repository
M Locally modified U Updated in repository A Locally added D Locally deleted I Ignored R Replaced in the repository – The contents of the folder have mixed status; display the contents to see individual status ? Not under source control
This is because you might have selected option as shown in below image when you created your application project, so this creates a repository for your application:
A indicates Added Files M indicates Modified Files which are came by default with project
NO it just shows you the file is A for Added and M for Modified by user
It is probably because you enabled Git SCM when you created the project. M means modified, and A means added. When you commit the changes the markers will disappear.
