Table not found after adding preloaded sqlite db to iOS App using Xcode

Below is the code which worked:

    func copyDataBase() -> Bool {    let fileManager = FileManager.default    var dbPath = ""    do {        dbPath = try fileManager.url(for: .applicationSupportDirectory, in: .userDomainMask, appropriateFor: nil, create: true).appendingPathComponent(dbFileName).path    } catch {        print(error.localizedDescription)        return false    }    if !fileManager.fileExists(atPath: dbPath) {        let dbResourcePath = Bundle.main.path(forResource: "dbName", ofType: "sqlite")        do {            try fileManager.copyItem(atPath: dbResourcePath!, toPath: dbPath)        } catch {            print(error.localizedDescription)            return false        }    }    return true}

I hope this will help somebody in need

  Firstly Create FileManager Object. Get Path and check file is exist or not then copy items from db.     func callForCopyDBAllObejct() -> Bool {     let fileM = FileManager.default     var dbPath = nil    do {      dbPath = try fileM.url(for: .applicationSupportDirectory,  in: .userDomainMask, appropriateFor: nil, create:    true).appendingPathComponent(dbFileName).path   } catch {      print(error.localizedDescription)       return false   }     if !fileM.fileExists(atPath: dbPath) {       let dbResourcePath = Bundle.main.path(forResource: "dbName",    ofType: "sqlite")       do {         try fileM.copyItem(atPath: dbResourcePath!, toPath:     dbPath)       } catch {        print(error.localizedDescription)        return false       }   }   return true
