See more ULID/UUID Examples

Checks to see if a ULID is valid.

Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Swift

func chilkatTest() {
    let dt = CkoDateTime()!

    // A ULID must be exactly 26 chars in length,
    // and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
    // Note: The ULID alphabet excludes the letters I, L, O, and U

    // Here's a valid ULID
    var ulid: String? = "01GRGCH4J88RECEN4D4VK4F629"
    var valid: Bool = dt.ulidValidate(ulid: ulid)
    print("valid: \(valid)")

    // Here's an invalid ULID
    ulid = "71GRGxx4Jr8RECEN4D4VK4F62!"
    valid = dt.ulidValidate(ulid: ulid)
    print("valid: \(valid)")
