title: "Payment not completed" with Apple Pay - can't get token
body: <p>I am implementing Apple Pay using PassKit, I am showing the dialog the proper way and handling the delegate methods, but every time I use touch Id to verify a purchase it says "Payment not completed" and never reaches my delegate method <code>paymentAuthorizationViewController:didAuthorizePayment:completion:</code>. I did all of <a href="https://stackoverflow.com/a/26476470/431271">these things</a> fully to set up apple pay, but I cant seem to get a token back to send to my payment gateway.</p>
  
  <pre><code>PKPaymentRequest *request = [[PKPaymentRequest alloc] init];
  self.paymentRequest = request;
  request.countryCode = @"US";
  request.currencyCode = @"USD";
  request.supportedNetworks = @[PKPaymentNetworkAmex, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];
  request.merchantCapabilities = PKMerchantCapabilityEMV;
  request.merchantIdentifier = @"merchant.com.*******";
  request.requiredShippingAddressFields = PKAddressFieldPostalAddress;
  request.requiredBillingAddressFields = PKAddressFieldPostalAddress;
  
  request.paymentSummaryItems = [self paymentSummaryItems];
  self.paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];
  self.paymentPane.delegate = self;
  if (self.paymentPane) {
      [self presentViewController:self.paymentPane animated:TRUE completion:nil];
  }
  </code></pre>
  
  <p>Here is what I am seeing, and the screen just stays there and says "Try Again" over and over:</p>
