How To Pass Dictionary To Another Dictionary In A Different View Controller - swift

Question

I have two view controllers (autoClaimViewController and reviewAutoViewController). In autoClaimViewController, I have a dictionary (reviewTableViewData) that is made up of a struct called claimData (it contains two string variables and a UIImage variable). When the user hits the "Review" button, I want the reviewTableViewData dictionary to be passed to the second view controller so that it's data can be displayed on a table view in the second view controller (reviewAutoViewController). How do I pass this dictionary to the other view controller?
Please make your answers understandable for a beginner - I'm still learning. I'm moving between view controllers using storyboard segues.
Thanks.
Additional Question: Will the images that I stored in the variables be passed when the dictionary is passed? In other words, do images work like Integers and Strings, where they can be passed between variables without an issue?
My code:
struct claimData {
var images = UIImage()
var imageTitle = String()
var relatedUnrelated = String()
}
class autoClaimViewController: UIViewController {
var reviewTableViewData = [claimData]()
#IBAction func reviewButton(_ sender: Any) {
//PASSES THE INFORMATION TO THE REVIEW VIEW CONTROLLER
//FIX THIS... IT NEEDS TO SEND THE reviewTableViewData ARRAY.
//MAKE A DICTIONARY IN THE REVIEW CONTROLLER THAT RECEIVES THE DICTIONARY FROM THIS VIEW CONTROLLER.
let vc2 = reviewAutoViewController()
//Find out how to transfer a dictionary from one view controller to another
}

I think your best bet is to set up a segue in your storyboards which takes you from 1st view to the second view. Here is a guide.
https://developer.apple.com/library/archive/featuredarticles/ViewControllerPGforiPhoneOS/UsingSegues.html
In both views have a place to store the information you want to pass. So create a var in the secon view to hold reviewTableViewData from the first view.
Then in the 1st view you call
override func prepare(for segue: UIStoryboardSegue, sender: Any?)
{
if segue.destination is reviewAutoViewController
{
let vc = segue.destination as? TertiaryViewController
vc?.reviewTableViewData = reviewTableViewData
}
}
This get the data ready to be sent.
Then you perform the segue and the data should be passed for you. Perfomr the seugue with this func triggered by the button or whatever you use to tranisiton between views.
func performSegue(withIdentifier identifier: String,
sender: Any?){
