Verification code always invalid using Swift Parse and Twilio - swift

Question

Im using SMS verification to verify users. My problem is that when I enter a code to verify I get invalid code. I can't for the life of me figure out why.
Calling cloud code function:
#IBAction func verifyCodeButtonTapped(sender: AnyObject) {
var verificationCode: String = verificationCodeTextField.text!
let textFieldText = verificationCodeTextField.text ?? ""
if verificationCode.utf16.count != 4 {
displayAlert("Error", message: "You must entert the 4 digit verification code sent yo your phone")
} else {
let params = ["verifyPhoneNumber" : textFieldText]
PFCloud.callFunctionInBackground("verifyPhoneNumber", withParameters: params, block: { (object: AnyObject?, error) -> Void in
if error == nil {
self.performSegueWithIdentifier("showVerifyCodeView", sender: self)
} else {
self.displayAlert("Sorry", message: "We couldnt verify you. Please check that you enterd the correct 4 digit code sent to your phone")
}
})
}
}
Cloud code to verify code:
Parse.Cloud.define("verifyPhoneNumber", function(request, response) {
var user = Parse.User.current();
var verificationCode = user.get("phoneVerificationCode");
if (verificationCode == request.params.phoneVerificationCode) {
user.set("phoneNumber", request.params.phoneNumber);
user.save();
response.success("Success");
} else {
response.error("Invalid verification code.");
}
});

In the Parse code, you are expecting request.params.phoneVerificationCode but when you call the cloud function from iOS you let params = ["verifyPhoneNumber" : textFieldText].
So, either change that line to
let params = ["phoneVerificationCode" : textFieldText]
so that it matches the cloud code. Or change your cloud code to
if (verificationCode == request.params.verifyPhoneNumber) {
so that it matches the iOS code.
