Sherlock and The Beast

  • Bob_Roebling + 0 comments

    Extension for Swift to multiply Strings/Characters. Don't forget to unwrap the optional.

    extension String {
	public init?(byRepeatingString str: String, count: Int) {
		var newString = ""

		for _ in 0 ..< count {
			newString += str
		}

		self.init(newString)
	}
}
