It&amp;#x27;s a modern SQLite wrapper with a lot of conveniences for application development like value types, Codable mapping, Combine observables, etc.&lt;p&gt;I&amp;#x27;ve deployed it in production on a few apps so far, and it has been a real joy to use.&lt;p&gt;1. &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;groue&amp;#x2F;GRDB.swift&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;groue&amp;#x2F;GRDB.swift&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>Dflat: SQLite FlatBuffers</title><url>https://github.com/liuliu/dflat</url></story>

Is there a way to prevent that? If you have a column “PRIMARY KEY INTEGER”, it is your row id and it won’t change on vacuum, otherwise if you rely on automatic row id, you may have a surprise later.</text><parent_chain></parent_chain></comment><story><title>Dflat: SQLite FlatBuffers</title><url>https://github.com/liuliu/dflat</url></story>
