Swift: Create String given length same character

How can you create a String of a given length consisting of the same character - without using a loop?

Ie: create a String 10 characters in length where each character is an asterisk:


Similar to this approach in Java:
new String(new char[n]).replace("\0", s);

There's a String initializer for that:

init(repeating repeatedValue: String, count: Int)

Creates a new string representing the given string repeated the specified number of times.

let string = String(repeating: "*", count: 10)
