What is Understanding and using Closures?
Understanding closures involves knowing their syntax, how they capture surrounding values, and how to use them as function parameters and return values. Swift offers shorthand argument names and trailing closure syntax to keep closure usage concise. Closures appear throughout the Swift standard library and iOS SDK as the primary mechanism for passing behavior between components.
