I want to use a local database and I'm using fmdb library.
now I want to open my local database but I got this error :
value of type stringByAppendingPathComponet
my code:
func openDatabase() {
    let resourcePath = Bundle.main.resourceURL!.absoluteString
    let dbPath = resourcePath.stringByAppendingPathComponent(dbFileName)
    let database = FMDatabase(path: dbPath)
    /* Open database read-only. */
    if (!database.openWithFlags(1)) {
        print("Could not open database at \(dbPath).")
    } else {
        self.database = database;
    }
}
