Please excuse me, i'm relatively new to ios coding:

I have implemented an actionSheet with "Cancel" and "Buy" buttons. The Buy button action executes successfully, no problem.

But, what I want to do, is add another (2nd) action that lets user automatically segue to another screen after the original (1st) action is called.

Simplified: I want to press the Buy button (on my actionSheet) which downloads product, and then want to be automatically taken to the download screen to see my new downloads.

private func setBuyButton() -> Void 

 // Buy button action sheet
 actionSheet = UIAlertController(title: "CONFIRM PURCHASE", message: "(self.products.title) will be added to your Download page", preferredStyle: .actionSheet)

 let cancel = UIAlertAction(title: "Cancel", style: .cancel, handler: nil)

 let confirmPurchase = UIAlertAction(title: "Buy", style: .default) action in

 var productList = [String: Bool]()
 let productSetName = [self.productSetId : true]

 self.product.map( (drop: Drop) -> Void in
 productList[product.productKey] = true
 )

 if let userId = KeychainWrapper.standard.string(forKey: KEY_UID) 
 let downloads = ["product": productList, "productset": productSetName]
 DataService......blah, blah, blah...

 
 

 actionSheet.addAction(confirmPurchase)
 actionSheet.addAction(cancel)

With a programmatically.

Create a file DownloadView with the subclass of UICollectionViewController, then in your action add these code

let layout = UICollectionViewFlowLayout()
let controller = DownloadView.init(collectionViewLayout: layout)
self.navigationController?.pushViewController(controller, animated: true)

Also, if you don't need a collectionView, create a file with subclass of UIViewController and push it like this

self.navigationController?.pushViewController(DownloadView(), animated: true)

With Storyboard

Add viewController with identifer down and write these code in action handler

let downloadView = self.storyboard?.instantiateViewController(withIdentifier: "down") as! DownloadView
self.present(downloadView, animated:true, completion:nil)

In your storyboard, control click the yellow circle icon above the view controller and drag to the destination view controller to create a segue.

Select the segue and give it an identifier

Now you can call performSegue(withIdentifier:sender:) in your first view controller to segue programatically. In your case, put

self.performSegue(withIdentifier: "yourCustomSegue", sender: nil) 

in your row action handler will do the trick.
