(Swift 2) Generate Monotonic ULIDsSee more ULID/UUID ExamplesGenerate a sequence of monotonic ULIDs all using the same seed time. This code sample generates a series of ULIDs with continuously increasing values. Important: Chilkat's ULID functionality was introduced in v9.5.0.94.
func chilkatTest() { let seedDt = CkoDateTime() // You can set the seed time to any desired value. // In this example, the seed time is set to the current system date/time. seedDt.SetFromCurrentSystemTime() // Generate the 1st ULID in the series. // (i.e. the current UTC UNIX-time) var utc: Bool = true var ulid: String? = seedDt.UlidGenerate(utc) print("\(ulid!)") // Store the ULID in a Chilkat StringBuilder to generate the series. let sbUlid = CkoStringBuilder() sbUlid.Append(ulid) var i: Int = 0 while i < 50 { seedDt.UlidIncrement(sbUlid) print("\(sbUlid.GetAsString())") i = i + 1 } // Sample output: // 01GRGH30H8DMQ4F9A0XCTZHPGM // 01GRGH30H8DMQ4F9A0XCTZHPGN // 01GRGH30H8DMQ4F9A0XCTZHPGP // 01GRGH30H8DMQ4F9A0XCTZHPGQ // 01GRGH30H8DMQ4F9A0XCTZHPGR // 01GRGH30H8DMQ4F9A0XCTZHPGS // 01GRGH30H8DMQ4F9A0XCTZHPGT // 01GRGH30H8DMQ4F9A0XCTZHPGV // 01GRGH30H8DMQ4F9A0XCTZHPGW // 01GRGH30H8DMQ4F9A0XCTZHPGX // 01GRGH30H8DMQ4F9A0XCTZHPGY // 01GRGH30H8DMQ4F9A0XCTZHPGZ // 01GRGH30H8DMQ4F9A0XCTZHPH0 // 01GRGH30H8DMQ4F9A0XCTZHPH1 // 01GRGH30H8DMQ4F9A0XCTZHPH2 // 01GRGH30H8DMQ4F9A0XCTZHPH3 // 01GRGH30H8DMQ4F9A0XCTZHPH4 // 01GRGH30H8DMQ4F9A0XCTZHPH5 // 01GRGH30H8DMQ4F9A0XCTZHPH6 // 01GRGH30H8DMQ4F9A0XCTZHPH7 // 01GRGH30H8DMQ4F9A0XCTZHPH8 // 01GRGH30H8DMQ4F9A0XCTZHPH9 // 01GRGH30H8DMQ4F9A0XCTZHPHA // 01GRGH30H8DMQ4F9A0XCTZHPHB // 01GRGH30H8DMQ4F9A0XCTZHPHC // 01GRGH30H8DMQ4F9A0XCTZHPHD // 01GRGH30H8DMQ4F9A0XCTZHPHE // 01GRGH30H8DMQ4F9A0XCTZHPHF // 01GRGH30H8DMQ4F9A0XCTZHPHG // 01GRGH30H8DMQ4F9A0XCTZHPHH // 01GRGH30H8DMQ4F9A0XCTZHPHJ // 01GRGH30H8DMQ4F9A0XCTZHPHK // 01GRGH30H8DMQ4F9A0XCTZHPHM // 01GRGH30H8DMQ4F9A0XCTZHPHN // 01GRGH30H8DMQ4F9A0XCTZHPHP // 01GRGH30H8DMQ4F9A0XCTZHPHQ // 01GRGH30H8DMQ4F9A0XCTZHPHR // 01GRGH30H8DMQ4F9A0XCTZHPHS // 01GRGH30H8DMQ4F9A0XCTZHPHT // 01GRGH30H8DMQ4F9A0XCTZHPHV // 01GRGH30H8DMQ4F9A0XCTZHPHW // 01GRGH30H8DMQ4F9A0XCTZHPHX // 01GRGH30H8DMQ4F9A0XCTZHPHY // 01GRGH30H8DMQ4F9A0XCTZHPHZ // 01GRGH30H8DMQ4F9A0XCTZHPJ0 // 01GRGH30H8DMQ4F9A0XCTZHPJ1 // 01GRGH30H8DMQ4F9A0XCTZHPJ2 // 01GRGH30H8DMQ4F9A0XCTZHPJ3 // 01GRGH30H8DMQ4F9A0XCTZHPJ4 // 01GRGH30H8DMQ4F9A0XCTZHPJ5 // 01GRGH30H8DMQ4F9A0XCTZHPJ6 } |
