Swift version: 5.0
Swift strings have a built-in initializer that lets you create strings by repeating a string a certain number of times. To use it, just provide the string to repeat and a count as its two parameters, like this:
let str = String(repeating: "a", count: 5)
That will set
str to “aaaaa”.
