upload excel using alamofire

Question

i try to upload an excel file using alamofire in iOS. my file path is

file:///Users/macbook/Library/Developer/CoreSimulator/Devices/75477755-3367-41DE-B3D2-A2E22C7AE069/data/Containers/Data/Application/45CB65D0-0B7C-4F17-89AA-2163301F2E6B/Documents/appImportContacts.xls

and the code I use

    // import Alamofire
func uploadWithAlamofire(filePath : String ) {

    let url = URL(fileURLWithPath: filePath)//"/foo/bar/file.text")
    let dirUrl = url.deletingLastPathComponent()
    print(dirUrl.path)
    // Output: /foo/bar

    let fileURL = Bundle.main.url(forResource: "appImportContacts", withExtension: "xls", subdirectory: dirUrl.path)

    Alamofire.upload(fileURL!, to: "http://192.168.1.213/api/app/UploadExcelFile").responseJSON { response in
        debugPrint(response)
    }

I get fileURL nil

How can I make my file path as Bundle to pass to alamofire?
