StringPadding

Swift String padding μ Library.

API

The String extension provides a convenience method that defaults to right padding with whitespace filling:

String.padded(length: Int, filler: Character = " ", padding: Padding = .right) -> String

The underlying String.Padding enum can be used directly, too. For example:

let leftPadding = String.Padding.left
let rightPadding = String.Padding.right
let centerPadding = String.Padding.center

The String.Padding cases in turn expose:

String.Padding.pad(text: String, length: Int, filler: Character = " ") -> String

Usage

Use the convenience extension on String:

"y".padded(length: 5, filler: "x", padding: .right)
// "yxxxx"

That's useful to justify lines of text:

["$9.99", "$100.00"]
    .map { $0.padded(length: 10, padding: .left) }
    .join(separator: "\n")
// "     $9.99"
// "   $100.00"
