Step 7: Specify the version and build number

1. In Xcode, select your project in the project navigator.

2. Choose the target from the Project/Targets pop-up menu or in the Targets section of the project and targets sidebar.

3. In the Identity section of the General pane, specify the version and build number for your app.

   The format for the version string is number.number.number (for example, 1.0.1). The build number specifies which build you shipped for a specific app version. For more information, search for CFBundleShortVersionString and CFBundleVersion in the Xcode documentation.
