ViewController | view controller manages set of views | User Interface library

I'm sending push notification's with OneSignal, I'm receiving them fine. My problem is, is that when I click on the notification, I'd like it to open the notification url. I have the notificationUrl, but loading the url in my WKWebView is my problem. I am using SwiftUi App lifecycle, and not UiKit. So take in note that I don't have a ViewController.

I've tried using UIApplication.shared.open(URL(string: notificationUrl)!) but this opens the link in the browser.

Here's my notification opened handler in AppDelegate.

For some reason I can't get hardware keyboard shortcuts to work in iPadOS 15 (beta 5). They work for most keys, but not for arrow keys and tab key.

The same code seems to work well when compiled in Xcode 13 (beta 4) and run on iPadOS 14.5 simulator, but then refuses to work when built with same Xcode but on iPadOS 15 sim. I've tried it on actual devices with iPadOS 15 betas up to 5 with same results.

Here is a minimal example:

UITableView with multiple sections without section footers is shown with an extra space between sections. Xcode's view debugger shows that it's not a view, but just an empty space.

In my case the behavior is unwanted.

Playing with adding a 1.0/0.0 height footer doesn't help. Neither does changing the table view's style.

Here's a sample code:

I made a custom collection view flow layout that can toggle (with animation) between "film-strip" and "list" layouts. But after adding some fancy animations to the edge cells, the toggle animation broke. Here's what it looks like currently, without those changes:

The animation is nice and smooth, right? Here's the current, working code (full demo project here):

I have a UIKit project with UIViewControllers, and I'd like to present an action sheet built on SwiftUI from my ViewController. I need to bind the appearance and disappearance of the action sheet back to the view controller, enabling the view controller to be dismissed (and for the display animation to happen only on viewDidAppear, to avoid some weird animation behavior that happens when using .onAppear). Here is a code example of how I expect the binding to work and how it's not doing what I'm expecting:

I have the a red color stack view.

It contains a label and a purple custom view.

It looks as following

What I would like to achieve is

1. Label's top left (x, y) will always remain the same during animation.
2. Purple custom view's top left (x, y) will always remain the same during animation.
3. During animation, the red stack view will animate gracefully, based on the animation of purple custom view.

I use the following code

I'm trying to transition my collection view between a horizontal film-strip layout and a vertical stack layout.

This is what I'm currently doing:

1. Using setCollectionViewLayout(_:animated:completion:) to transition between horizontal and vertical scroll direction
2. Changing the height constraint of the collection view, along with UIView.animate and self.view.layoutIfNeeded()

The animation from film-strip to vertical stack is fine. However, the animation from vertical stack to film-strip is broken. Here's what it looks like:

If I make collectionViewHeightConstraint 300 by default, and remove these lines:

I am trying to create a custom UISearchBar that is placed as the titleView of a navigationController. Using the following code, the suggestionTableView of suggestions appears perfectly; however, It does not recognize any taps. In fact, it is like the suggestionTableView isn't even there because my taps are being sent to another view under the suggestion suggestionTableView. I was told that I could use hitTest(...) to catch these touches, but I don't know how I would implement this in my SuggestionSearchBar or in my ViewController. How can I send these touches to the suggestionTableView?

SuggestionSearchBar

I tend to hide the status bar, animated in the following way.
