"No such function: REGEXP" in sqlite3 on iOS

Question

Is it possible to rebuild libsqlite3.dylib with the regexp function added? Or use create_sqlite_function to do it?

Answer 1

As the SQLite documentation says:

If a application-defined SQL function named "regexp" is added at run-time, that function will be called in order to implement the REGEXP operator.

so you should be able to use create_sqlite_function like you already suggested yourself.
