I'm already using FTS3, after adding sqlite amalgamation as static library end enabling FTS3 (following this tutorial http://longweekendmobile.com/2010/06/16/sqlite-full-text-search-for-iphone-ipadyour-own-sqlite-for-iphone-and-ipad/).
The database the app is searching into contains copyrighted text, so I have decided to use SQLCypher commercial version and it includes FTS3 already enabled, if I'm not mistaken.
I haved added SqlCipher static library following http://sqlcipher.net/support/ and then removed previously added sqlite static library, is this correct? should I keep only libsqlcipher.a in my project?
Thanks for supporting SQLCipher by using iOS commercial edition! You are correct, you can simply have libsqlcipher.a linked with your project, it contains everything you need for all platforms.
