Here's a repo we just released that builds the `spellfix` plugin for the OS-distro version of #SQLite on #macOS, #iOS, and iOS-Simulator aarch64.
The version of SQLite that ships on macOS and iOS is pretty stripped down, to make it small. We've needed to use some extensions and getting them to compile and work with the off-the-shelf SQLite is not trivial. I previously evolved another plugin and made nice Makefile support for this. `spellfix` is much easier to handle.
