SQLite singleton class in Swift ( FMDB wrapper )

Question

I am working on Swift singleton class to integrate SQLite easily ( Using FMDB wrapper class )

Simple methods to create database in directory, insert and fetch data.

Bridging support for FMDB Objective C usage in Swift.

let contactDB = FMDatabase(path: String(methodToCreateDatabase()!.absoluteString) )

if contactDB.open() {

    let insertSQL = strQuery

    let result = contactDB.executeUpdate(insertSQL,
                withArgumentsInArray: nil)

    if !result {
                print("Failed to add contact")
                print("Error: \(contactDB.lastErrorMessage())")
        return false
    } else {
        print("Contact Added")
                return true
    }
} else {
     print("Error: \(contactDB.lastErrorMessage())")
     return false
}
