How To Finish Completion Block - Swift / Stripe Payments

This is the block I have:

func createBackendChargeWithToken(_ token: STPToken, completion: @escaping STPTokenSubmissionHandler) {
    if backendChargeURLString != "" {
        if let url = URL(string: "https://wt-lightfalldev-gmail-com-0.run.webtask.io/stripe-payment/payment") {
           let chargeParams : [String: AnyObject] = ["stripeToken": token.tokenId as AnyObject, "amount": shirtPrice as AnyObject]

           Alamofire.request(url, method: .post, parameters: chargeParams, encoding: JSONEncoding.default, headers: heads).responseJSON { (response:DataResponse<Any>) in

               switch(response.result) {
               case .success(_):
                  if response.result.value != nil{
                      print(response.result.value!)
                  }
                  break

               case .failure(_):
                  print(response.result.error!)
                  break                        
               }
           }
       }
   }
   completion(STPBackendChargeResult.failure, NSError(domain: StripeDomain, code: 50, userInfo: [NSLocalizedDescriptionKey: "You created a token! Its value is \(token.tokenId!). Now configure your backend to accept this token and complete a charge."]))
}

but this needs to be in it but I don't know how to write it correctly:

if (error) {  
    completion(STPBackendChargeResultFailure, error);
} else {
    completion(STPBackendChargeResultSuccess, nil);
}

The code is always calling the completion callback with STPBackendChargeResult.failure. So it needs to be an if statement and I need to call the completion callback with either failure or success depending on the result of the Alamofire request to send the token to the backend server.

Why can't you just put it in the switch?

switch(response.result) {
case .success(_):
    if response.result.value != nil{
        print(response.result.value!)            
    }
    completion(STPBackendChargeResultSuccess, nil)
case .failure(_):
    print(response.result.error!)
    completion(STPBackendChargeResultFailure, error)
}
