A example iOS project that reproduces an iOS build error when using Adobe Experience Platform Mobile SDKs and SQLCipher together in the same iOS project. Many attempts at the solution suggested here have not worked.
Summary of the problem is this line of code in Adobe's AEPServices library causes the Redefinition of 'sqlite3_file' error.
SQLCipher has a disclaimer that depending on pods which use SQLite is not a recommended approach, but that it should still be possible to get working.
