Base62

Base62 is a tiny package for Base62 encoding/decoding values. It is tested, documented, easy-to-use and supports Apple Platforms, as well as Linux.

I use this as encoding mechanism for my own URL shortener but this is a general purpose implementation that should suffice all use cases that require Base62 encoding/decoding.

Installation

Base62 is distributed using the Swift Package Manager. To install it into a project, add it as a dependency within your Package.swift manifest:

let package = Package(
    ...
    dependencies: [
        .package(url: "https://github.com/marcelvoss/Base62.git", from: "0.1.0")
    ],
    ...
)

Then import Base62 wherever you’d like to use it:

import Base62

Usage

Using Base62 is incredibly easy, as it focusses on a single responsibility and does that nicely.

Base62 ships with a single object that provides encoding and decoding functionality.

let base62Encoded = Base62.encode(2021)
// 2021 == "wz"

let base62Decoded = try Base62.decode("GitHub")
// "GitHub" == 38750631667

There are also extensions for String and Int available, if you prefer to use them rather than the Base62 object directly.
