ulid.swift's Issues
Create new version due to changed master branch
You should probably create a new version after your latest merge
Batch generation of ULIDs not lexicographically sorted
It happened to generate multiple ULID close one another in time. The generated values are unique but not lexicographically sorted following the creation time.
A simple code snippet to reproduce it:
(0..<10).enumerated().forEach { idx, _ in
print("\(ULID().ulidString) \(idx)")
}
| Actual result | Index | Expected (sorted) result | Index |
