This gist provides a simple example of how a UIAlertController can be used to obtain and provide visit feedback.

FSQVisitFeedbackAlertController.swift

extension UIAlertController {
    static func presentFeedbackAlertControllerForVisit(_ visit: Visit, controller: UIViewController, dismiss: (() -> Void)? = nil) {
        let alertController = UIAlertController(title: "Provide feedback:", message: visit.description, preferredStyle: .actionSheet)

        if let pilgrimVisitId = visit.pilgrimVisitId, let feedbackProvider = PilgrimManager.shared().feedbackProvider {
            
            // Correct Venue
            let correctAction = UIAlertAction(title: "Confirm", style: .default) { (action) -> Void in
                feedbackProvider.leaveVisitFeedback(.confirm, visitId: pilgrimVisitId, actualVenueId: nil, completion: nil)
            }
            
            // False Stop
            let falseStopAction = UIAlertAction(title: "False stop", style: .default) { (action) -> Void in
                feedbackProvider.leaveVisitFeedback(.falseStop, visitId: pilgrimVisitId, actualVenueId: nil, completion: nil)
            }
            
            // Wrong Venue
            let wrongVenueAction = UIAlertAction(title: "Wrong venue", style: .default) { (action) -> Void in
                // TODO: If selected, you should probably add an option for users to select the accurate venue
                // and send in the actual venue ID.
                feedbackProvider.leaveVisitFeedback(.wrongVenue, visitId: pilgrimVisitId, actualVenueId: nil, completion: nil)
            }
        
            // Deny Venue
            let denyAction = UIAlertAction(title: "Deny", style: .default) { (action) -> Void in
                feedbackProvider.leaveVisitFeedback(.deny, visitId: pilgrimVisitId, actualVenueId: nil, completion: nil)
            }
            
            // Add all actions
            alertController.addAction(correctAction)
            alertController.addAction(falseStopAction)
            alertController.addAction(wrongVenueAction)
            alertController.addAction(denyAction)
        }
        
        // Default Cancel
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)
        alertController.addAction(cancelAction)

        controller.present(alertController, animated: true, completion: dismiss)
    }
}
