The difference between Libsqlite3.dylib and Libsqlite3.0.dylib

Libsqlite3.dylib itself is a link, it points to libsqlite3.0.dylib.

That is to say in the project if you add libsqlite3.dylib and add libsqlite3.0.dylib actually add the same file, no difference, then why add libsqlite3.dylib?

The reason is that libsqlite3.dylib always points to the latest Sqlite3 dynamic library, which means that if a new dynamic library (such as: Libsqlite3.1.dylib) is present, Libsqlite3.dylib will point to this new dynamic library (libsqlite3.1.dylib) And it's not libsqlite3.0.dylib! So it is recommended to add libsqlite3.dylib!
