Swift get stripe charge id when payment has succeeded

Question

I am using stripe api to make a payment.

I am trying to receive the charge ID from the pay() function but do not see the charge id in any of the Param Variables. Is this something I have to do server side? I would assume the charge id would be in the payment intent params but it is not. Do I have to fetch the charge id some other way?

charge id example:

"id": "ch_1IXpNqHiSsWQPbMQ3dNTp73m"

I create a payment intent server side and process the payment like so: https://stripe.com/docs/payments/integration-builder

@objc
  func pay() {
    guard let paymentIntentClientSecret = paymentIntentClientSecret else {
        return;
    }
    // Collect card details
    let cardParams = cardTextField.cardParams
    let paymentMethodParams = STPPaymentMethodParams(card: cardParams, billingDetails: nil, metadata: nil)
    let paymentIntentParams = STPPaymentIntentParams(clientSecret: paymentIntentClientSecret)
    paymentIntentParams.paymentMethodParams = paymentMethodParams
    // Submit the payment
    let paymentHandler = STPPaymentHandler.shared()
    paymentHandler.confirmPayment(withParams: paymentIntentParams, authenticationContext: self) { (status, paymentIntent, error) in
      switch (status) {
      case .failed:
          self.displayAlert(title: "Payment failed", message: error?.localizedDescription ?? "")
          break
      case .canceled:
          self.displayAlert(title: "Payment canceled", message: error?.localizedDescription ?? "")
          break
      case .succeeded:
          self.displayAlert(title: "Payment succeeded", message: paymentIntent?.description ?? "")
          break
      @unknown default:
          fatalError()
          break
      }
    }
  }

Param output:

succeeded:

nil

status:

A PaymentIntent has all its Charges under the charges list [0] but that is only returned server-side, it is not currently retrievable via a Publishable key.

You would fetch the PaymentIntent server-side which will return you the entire charges list, with the most recent Charge being the first element in that list.
