In the app I'm using my library, the state is not null.

Maybe it's a side effect of something else?

SwiftUI is not conditionally linked? I'm getting crash on launch as SwiftUI can't be linked on any earlier iOS version than 13.

Perfect thanks!

Thanks for the answer,

I have a lot of dynamic text and content, so calculating the height manually sound like a step back from self sizing UITableView. But I'll provide reference size to some static components and see if it improves.

The UITableViewReloadDataUpdater didn't helped at all :(

Hello,

I'm making a fairly complexe UITableView, and I have some weird behaviours. As I scroll down, mostly no problem. As I scroll up I get really weird behaviours, like blank space (missing components?) and wrongly sized component.

Here is two images, one normal and one as I scroll up.

Here is some code, this is a quite complexe project, so very hard for me to extract and isolate to make it easy to reproduce for you guys. But maybe something is wrong in my approach.

Here is my datasource

And also the code of one of my component as an example

struct ReadingActivityQuoteComponent: IdentifiableComponent {
    let quote: Quote?
    let isTop: Bool
    
    var id: String {
        quote?.id ?? "quoteLoading"
    }
    
    class View: UIView {
        var quote: Quote? {
            didSet {
                render()
            }
        }
        
        var isTop: Bool = false {
            didSet {
                if isTop {
                    cardView.maskedCorners = [.topLeft, .topRight]
                } else {
                    cardView.maskedCorners = []
                }
            }
        }
        
        let quoteLabel = QuoteDarkerLeft(frame: .zero)
        let cardView = CardView(frame: .zero)
        
        init() {
            super.init(frame: CGRect.zero)
            
            cardView.maskedCorners = []
            
            quoteLabel.showAnimatedGradientSkeleton()
            quoteLabel.numberOfLines = 0
        
            addSubview(cardView)
            cardView.addSubview(quoteLabel)

            
            constrain(self, cardView, quoteLabel) { parent, card, quote in
                card.top == parent.top
                card.left == parent.readableContentGuide.left + 12
                card.right == parent.readableContentGuide.right - 12
                card.bottom == parent.bottom
                
                quote.top == card.top + 12
                quote.left == card.left + 12
                quote.right == card.right - 12
                quote.bottom == card.bottom - 12
            }
        }
        
        required init?(coder: NSCoder) {
            fatalError("init(coder:) has not been implemented")
        }
        
        func render() {
            quoteLabel.hideSkeleton()
            quoteLabel.text = quote?.text
        }
    }
    
    func renderContent() -> ReadingActivityQuoteComponent.View {
        View()
    }
    
    func render(in content: ReadingActivityQuoteComponent.View) {
        content.quote = quote
        content.isTop = isTop
    }
}

Coming from a lot of SwiftUI lately, Carbon is really awesome to use in the UIKit world. But I'm having quite some issues right now. Again, I have no idea if my architecture is wrong or if I'm hitting some underlying Carbon or UITableView related bugs. I'm self sizing every component with auto layout using Cartography.

1. Go to the movie detail view
2. Wait for keywords cell to appear
3. Select the cell
4. App presents the next view, then navigates back to movie details view and crashes:

Yup. This was fixed by Apple in iOS 13 GM :)

When the score is 61%, the badge's shadow is out of the circle's boundary.

I have tested and verified that if the trim is to 0.61, the circle shape will become a part, its shadow will departure the original position.

How to solve this?

And for the interested I've made a very lightweight ReSwift for SwiftUI here: https://github.com/Dimillian/SwiftUIFlux

If it works you could do a proper pull request, It's nice that the app will open back on the last used tab. Note; It could also be backed in a UIState in the redux app state, like the movies and peoples state, it could be saved on app quit, and restored on launch.

I was perusing the code and noticed that this was probably intended to be .topRated.

Thanks!

My breakpoint is shown, so the code is called. Are you sure you touch save on the settings form?
