Please below code.. I update your code in two functions to copy all files from folder to document directory.

Hope it will work.

func copyFolders() {
    let fileManager = FileManager.default

    let documentsUrl = fileManager.urls(for: .documentDirectory,
                                        in: .userDomainMask)

    guard documentsUrl.count != 0 else {
        return // Could not find documents URL
    }

    let finalDatabaseURL = documentsUrl.first!.appendingPathComponent("Stickers")

    if !( (try? finalDatabaseURL.checkResourceIsReachable()) ?? false) {
        print("DB does not exist in documents folder")

        let documentsURL = Bundle.main.resourceURL?.appendingPathComponent("Stickers")

        do {
            if !FileManager.default.fileExists(atPath:(finalDatabaseURL?.path)!)
            {
                try FileManager.default.createDirectory(atPath: (finalDatabaseURL.path), withIntermediateDirectories: false, attributes: nil)
            }
            copyFiles(pathFromBundle: (documentsURL?.path)!, pathDestDocs: finalDatabaseURL.path)
        } catch let error as NSError {
            print("Couldn't copy file to final location! Error:\(error.description)")
        }

    } else {
        print("Database file found at path: \(finalDatabaseURL.path)")
    }

}

func copyFiles(pathFromBundle : String, pathDestDocs: String) {
    let fileManagerIs = FileManager.default
    do {
        let filelist = try fileManagerIs.contentsOfDirectory(atPath: pathFromBundle)
        try? fileManagerIs.copyItem(atPath: pathFromBundle, toPath: pathDestDocs)

        for filename in filelist {
            try? fileManagerIs.copyItem(atPath: "\(pathFromBundle)/\(filename)", toPath: "\(pathDestDocs)/\(filename)")
        }
    } catch {
        print("\nError\n")
    }
}
