Discussion 議論

Use the closed range operator (...) to create a closed range of any type that conforms to the Comparable protocol. This example creates a ClosedRange<Character> from “a” up to, and including, “z”. 完結範囲演算子(...)を使うことでComparableプロトコルに準拠する何らかの型の配列を作成してください。この例は、「a」から「z」までの、そしてそれを含むClosedRange<Character>を作成します。


let lowercase = "a"..."z"
print(lowercase.contains("z"))
// Prints "true"

Precondition: minimum <= maximum. 前提条件:minimum <= maximum
