Code signing is a security measure to provide proof that you are indeed the publisher of an app.

iOS Code Signing

Apple uses a process called "provisioning" for code signing your apps.

For more details about provisioning, please refer to the article Creating a provisioning profile.

Depending on the type of build you want to generate, you may need to create and add different provisioning profiles. For an overview of the different types of iOS builds, please refer to this page.
