sqlite3_prepare_v2 returns 1

For days I have a problem that is making me crazy.

I use the API swiftdata.swift on GitHub, link Here.

Well, if I launch my project on the iOS Simulator with Iphone6 it works beautifully, but if I use another iOS device the application crashes. I found that the error is due from instruction

func executeQuery(sqlStr: String, withArgs: [AnyObject]? = nil) -> (result: [SDRow], error: Int?) {            
        var resultSet = [SDRow]()            
        var sql = sqlStr
        if let args = withArgs {
            let result = bind(args, toSQL: sql)
            if let err = result.error {
                return (resultSet, err)
            } else {
                sql = result.string
            }
        }            
        var pStmt: COpaquePointer = nil
        var status = sqlite3_prepare_v2(SQLiteDB.sharedInstance.sqliteDB, sql, -1, &pStmt, nil)
        if status != SQLITE_OK {
            println("SwiftData Error -> During: SQL Prepare")
            println("                -> Code: \(status) - " + SDError.errorMessageFromCode(Int(status)))
            if let errMsg = String.fromCString(sqlite3_errmsg(SQLiteDB.sharedInstance.sqliteDB)) {
                println("                -> Details: \(errMsg)")
            }
            sqlite3_finalize(pStmt)
            return (resultSet, Int(status))
        } 
.........

Why? I imported the library libsqlite3.0.dylib, I doubt that this library is related only for iPhone6. Can anyone help me?

I use Xcode 6.1

Thanks
