SwiftUI HStack with Wrap

问题

Is it possible that the blue tags (which are currently truncated) are displayed completely and then it automatically makes a line break?

NavigationLink(destination: GameListView()) {
                            VStack(alignment: .leading, spacing: 5){
                                // Name der Sammlung:
                                Text(collection.name)
                                    .font(.headline)
                                // Optional: Für welche Konsolen bzw. Plattformen:
                                HStack(alignment: .top, spacing: 10){
                                    ForEach(collection.platforms, id: \.self) { platform in
                                        Text(platform)
                                            .padding(.all, 5)
                                            .font(.caption)
                                            .background(Color.blue)
                                            .foregroundColor(Color.white)
                                            .cornerRadius(5)
                                            .lineLimit(1)
                                    }
                                }
                            }
                            .padding(.vertical, 10)
                        }

Also, there should be no line breaks with in the blue tags:

That's how it should look in the end:

Here is some approach of how this could be done using alignmentGuide(s). It is simplified to avoid many code post, but hope it is useful.

This is the result:

And here is full demo code (orientation is supported automatically):

import SwiftUI

struct TestWrappedLayout: View {
    @State var platforms = ["Ninetendo", "XBox", "PlayStation", "PlayStation 2", "PlayStation 3", "PlayStation 4"]

    var body: some View {
        GeometryReader { geometry in
            self.generateContent(in: geometry)
        }
    }

    private func generateContent(in g: GeometryProxy) -> some View {
        var width = CGFloat.zero
        var height = CGFloat.zero

        return ZStack(alignment: .topLeading) {
            ForEach(self.platforms, id: \.self) { platform in
                self.item(for: platform)
                    .padding([.horizontal, .vertical], 4)
                    .alignmentGuide(.leading, computeValue: { d in
                        if (abs(width - d.width) > g.size.width)
                        {
                            width = 0
                            height -= d.height
                        }
                        let result = width
                        if platform == self.platforms.last! {
                            width = 0 //last item
                        } else {
                            width -= d.width
                        }
                        return result
                    })
                    .alignmentGuide(.top, computeValue: {d in
                        let result = height
                        if platform == self.platforms.last! {
                            height = 0 // last item
                        }
                        return result
                    })
            }
        }
    }

    func item(for text: String) -> some View {
        Text(text)
            .padding(.all, 5)
            .font(.body)
            .background(Color.blue)
            .foregroundColor(Color.white)
            .cornerRadius(5)
    }
}

struct TestWrappedLayout_Previews: PreviewProvider {
    static var previews: some View {
        TestWrappedLayout()
    }
}

You need to handle line configurations right after Text View. Don't use lineLimit(1) if you need multiple lines.

 HStack(alignment: .top, spacing: 10){
                ForEach(collection.platforms, id: \.self) { platform in
                    Text(platform)
                    .fixedSize(horizontal: false, vertical: true)
                    .lineLimit(10)
                    .multilineTextAlignment(.leading)
                        .padding(.all, 5)
                        .font(.caption)
                        .background(Color.blue)
                        .foregroundColor(Color.white)
                        .cornerRadius(5)

                }
            }

I found a Framework-Solution called ASCollectionView. I hope this helps someone who has the same problem.
