The new one uses <a href="https://github.com/groue/GRDB.swift" class="external-link" target="_blank" rel="noopener">GRDB</a> on top of SQLite, with a <code>DatabaseMigrator</code> that&rsquo;s grown by three small migrations as features were added: create the table, add a color column, add a usage counter. Easier to reason about, and easier to extend without touching a <code>.xcdatamodeld</code> file.</p>
