Mastering Swift 2 Programming (Video 15)

The video tutorial explores the concept of flat map in Swift, demonstrating its use with single and multidimensional arrays, as well as optionals. It compares flat map with map, highlighting how flat map returns a flattened array without nil values. The tutorial also shows advanced usage of flat map with higher order functions and its application in game development, emphasizing code optimization. The video concludes with a brief overview of the next topic, reduce.
