If a variable, function or closure isn’t in a scope, you can’t access it. One way to provide the sorting closure is to write a normal function of the correct type, and to pass it in as an argument to the sorted(by:) method: If the first string (s1) is greater than the second string (s2), the backward(_:_:) function will return true, indicating that s1 should appear before s2 in the sorted array. In this example, the variable number is initialized with the value of the closure’s number parameter, so that the value can be modified within the closure body. Swift’s Closure Types Explained.

Let’s compare that to the target-action pattern, another common approach to invoke functions at a later point in time. Closures are also important for SwiftUI’s syntax. Swift will infer the type of age based on the context of the above code. } window.jQuery || document.write("
