Swift version: 5.2
You should already know that you can check whether a string contains a single word like this:
let string = "The rain in Spain" let stringResult = string.contains("rain")
You should also know that you can check an array of strings to see whether a particular string is in there, like this:
let words = ["clouds", "rain", "wind"] let arrayResult = words.contains("rain")
Well, both those
contains() methods can be combined together to form a new meaning: “do any of the words in this array exist in this string?” like this:
let combinedResult = words.contains(where: string.contains)
