How to check whether a string contains any words from an array
Swift version: 5.6
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)TAKE YOUR SKILLS TO THE NEXT LEVEL If you like Hacking with Swift, you'll love Hacking with Swift+ – it's my premium service where you can learn advanced Swift and SwiftUI, functional programming, algorithms, and more.
