I don't know why there are both accentColor and foregroundColor properties in SwiftUI. I can't see their differences. For example:

I have this code inside which I'm calling "makeView" function that returns a View, and in the makeView function I'm incrementing the variable "id" and passing it to the View, but when I do this it shows this error

"Updating a preview from SongsList_Previews in SongBook.app (2935) took more than 5 seconds."

And surprisingly when I comment out the line "self.id += 1" everything works. I'm new to SwiftUI, so forgive me if I left out some information.

How do I align the Color views in a straight line with the text to the side?

To look like so (text aligned leading):

█  red
█  green
█  blue

Or this (text aligned center):

█    red
█  green
█   blue

Current code:

I have been testing the async/await functionality previewed in the Swift 5.5 release, but I am unable to collect the results from an async function and display them using SwiftUI. Here is my code:

I am trying to call my JS function in my webview that takes 2 parameters using the evaluateJS however I do no appear to be hitting the function. (It works without params so I think I am getting the syntax wrong on the SwiftUI side. Wondering if anyone can advise please.

JS function:

Is it possible to create a widget in iOS 14+ without using SwiftUI? When adding the target it doesn't give you the option between storyboard and SwiftUI like it does when creating a new project. Is it possible to build out a Widget using Storyboard or XIB?

I am building an application where one of the pages has a webview. Currently the page has a the webview representable and a view. Webview is brought to the view using the UIViewControllerRepresentable. I am wondering firstly how when I tap the login button can I call a function inside the LoginWebview, and also secondly vice versa, how can I call a function in the LoginView from the LoginWebview. I currently have the set up so that when I click login it toggles the states which causes the updateUIView to trigger but how can I call a custom made function in there? And vice versa

Apologies for the long description above and if this a stupid question

Thanks :)

LoginView:

I'm hoping that I can attach a recording of my simulator to this request. I have a list of items that I create a NavigationLink for that call a child view with different data based on a value passed in. The child view is a large horizontal scroll view with pages that support months of the year. DragGesture controls the positioning of the horizontal scroll.

When I transition from the List to the child view it appears almost like it is swooping in from the right and when it transitions back to the parent list view you can see visual from both views appear briefly during the transition.

I believe it has something to do with the GeometryReader and Horizontal Scroll view, but can't figure out how to stabilize it...

The list view is:

I know how a custom ButtonStyle works. But I do want to have a fully reusable custom button.

Aka a button with Text and and Icon that has some styles applied.

I know how to achieve this using a ButtonStyle with a text property, but I think this is completely a misuse of button styles.

But I do not want to copy a Button with a large HStack as content all over my app.

What do you recommend in such use cases? It seems that no one has subclassed a Button in SwiftUI on the internet.
