In this challenge, you’ll learn about what’s happening behind the scenes when you save a String with its write method.

try string.write(to: <#T##URL#>, atomically: <#T##Bool#>, encoding: <#T##String.Encoding#>)

let catsURL = URL(fileURLWithPath: "Cats.txt", relativeTo: FileManager.documentsDirectoryURL)

…, atomically: true)

let catsChallengeString = try String(contentsOf: catsURL)
