let base32 = try uuid.shortened(using: .base32) // e9dlbzsyrie7pfu5hhx66b1m8

let base90 = try uuid.shortened(using: .base90) // n#g|6HlzuCBbxY~bho1!
// And get the original UUID back:
let original = try UUID(shortened: base62, using: .base62)
You may use short identifiers in URL instead of using the full base16 UUID.
One of the best for URLs is base62 (no special characters), although base64 will work here.
If you need to disambiguate characters, base58 with alike characters stripped is best.
