Error Domain=com.uber.rides-ios-sdk.ridesAuthenticationError Code=19

[Zulqurnain24]

Hi,
I have followed the procedure listed for uber sdk configuration page https://developer.uber.com/docs/riders/ride-requests/tutorials/api/ios but I am getting this error

"Error Domain=com.uber.rides-ios-sdk.ridesAuthenticationError Code=19 "The Redirect URI provided did not match what was expected." UserInfo={NSLocalizedDescription=The Redirect URI provided did not match what was expected."

when I use this syntax
"let loginManager = LoginManager()
loginManager.login(requestedScopes:[.request], presentingViewController: self, completion: { accessToken, error in
// Completion block. If accessToken is non-nil, you’re good to go
// Otherwise, error.code corresponds to the RidesAuthenticationErrorType that occured
})"

Can someone help me with this. Thanks in advance.
