iOS adds programming interfaces to the NSIndexPath class of the Foundation framework to facilitate the identification of rows and sections in UITableView objects. The API consists of a class method and two properties. The indexPathForRow:inSection: method creates an NSIndexPath object from row and section index numbers. The properties return the row index number and the section index number from such objects

What's the difference in rows and sections in NSIndexPath in Swift?
