Solution #1:

Expression<String>("id")

For this line just simply add SQLite. As a result we should have:

SQLite.Expression<String>("id")

Solution #2, global fix:

typealias Expression = SQLite.Expression

or

import SQLite.Expression

Just put this at the beginning. I searched a lot but didn't find any similar titles or solutions for this error at first, therefore maybe it would be useful for someone. Any other interesting solutions?
