Swift Package exposing embedded SQLite library

[ir-fuel]

Hi

We have an issue here with the SQLite library used inside this library when used via Swift Package Manager.

it seems the SQLite library included also exposes all its symbols to the application when using Couchbase Lite, and global calls such as sqlite3_version and others go to that library, and not the default one provided by Apple.

The issue is we use another third party library (from Adobe) that also uses SQLite internally, but does not include its own version of the SQLite library. The library provided by Apple has other compile options and the Adobe library no longer functions when used at the same time as Couchbase Lite because the SQLite database operations fail in that Adobe library.

It took a while to figure out, but after setting some breakpoints I discovered this issue. Is there a way to avoid this so all other code in my project does not call the functions of the included SQLite library, but uses the global one iOS provides?

CouchbaseLiteSwift also exports those internal symbols unfortunately. We need to fix these by not including the sqlite_* symbols in the binary file. Basically we need to set the EXPORTED_SYMBOLS_FILE with the list of public symbols. We do that for Objective-C framework but not for Swift. The swift symbols need to be generated as they are in the mangled format and they are for everything (class, method, property, etc).

I have created an internal ticket CBL-7590 with the info.
