I am creating a reference application. On the main screen are rows of icons, when you click on each, a card with information about the item should pop up. I could not figure out how to create a popup window in Xcode using Swift. A pop-up card should be blurring the background and closed with a down / up swipe. Ideally, it should look like an Instagram photo viewer. PS This is my first project and the knowledge of Swift leaves much to be desired, so please explain as much as possible. enter image description here

Decompose the task, first deal with the blur, then with transitions between the controllers.

Keywords for blur - UIBlurEffect, UIVisualEffect

Jump keywords - UIViewControllerAnimatedTransitioning, UIViewControllerInteractiveTransitioning

    Need something like that?

    Create a view controller in a storyboard. Put the UIVisualEffectView on the main view, your card on it. Everything. Call as follows.

    - (IBAction)pressMe:(id)sender { UIStoryboard* mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]; rateDialogVC = [mainStoryboard instantiateViewControllerWithIdentifier:@"RateDialogVC"]; [ViewController setPresentationStyleForSelfController:self presentingController:rateDialogVC]; [self presentViewController:rateDialogVC animated:YES completion:nil]; } + (void)setPresentationStyleForSelfController:(UIViewController *)selfController presentingController:(UIViewController *)presentingController { presentingController.providesPresentationContextTransitionStyle = YES; presentingController.definesPresentationContext = YES; presentingController.modalPresentationStyle = UIModalPresentationOverCurrentContext; }

    This is Objective-C sorry!
