eg:
func UUIDTest() {
let uuid = UUID(uuidString: "00000000-0000-0000-0000-000000000001")

How to generate safe RSA keys deterministically using a seed?
How do we use a mnemonic list of words as a seed (like we have been become accustomed using cryptocurrency wallets) to be able to recover a private key in case it gets lost, accidentally erased, or stuck on a broken device?
This could be useful for…

Generate valid, deterministic UUIDs for tests
For my ruby testsuite, I need predictable UUIDs. I am aware that UUIDs are by nature random and non-deterministic, and that this is good. But in the testsuite, it would be useful to have UUIDs that can be re-used through fixtures, data-helpers,…
