To run things on Linux we only really need a tiny subset of Combine, and the types for that are already prepared in Misc/NoCombine.swift.

We just need a way to track the sinks attached to a PassthroughSubject.

P.S.: A Swift 5.1 container would be also required of course.

hello, so I want to try this library to see if I can make apps with it. but when I try the steps in https://github.com/carson-katri/swiftwebui-scripts, I get error when running the command (make), and I get the following error : cd testingAppweUI &&

thank you for making this

Did rewrite connection to work with WebSocket. Theres few stuff which could be better. Isn't that always a case? Anyway. Need your input on this one.

How to update DOM object from within timer or request? @helje5 I've implemented two way communication, however it sends empty changes array or it crashes on your asserts. Help needed :) Thanks!

Hi @helje5 I just re-watched this WWDC talk: https://developer.apple.com/videos/play/wwdc2019/226/

At around 33:00 the speaker says that Binding does not capture references.

I tested it with BindableObject's subscript to verify the behavior.

public struct _Binding<Value> {
  private let _getter: () -> Value
  private let _setter: (Value) -> Void
  
  public var wrappedValue: Value {
    get {
      return _getter()
    }
    nonmutating set {
      _setter(newValue)
    }
  }
  
  public init(
    getValue getter: @escaping () -> Value,
    setValue setter: @escaping (Value) -> Void
  ) {
    _getter = getter
    _setter = setter
  }
}

class VM: BindableObject {
  let willChange = PassthroughSubject<Void, Never>()
  var value = ""
  
  public func getBinding<Subject>(
    keyPath path: ReferenceWritableKeyPath<VM, Subject>
  ) -> _Binding<Subject> {
    return _Binding(
      getValue: {
        self[keyPath: path]
      },
      setValue: { newValue in
        self[keyPath: path] = newValue
      }
    )
  }
}

var vm: VM = VM()
print(CFGetRetainCount(vm)) // 2
let biding_1: Binding<String> = vm[\.value]
print(CFGetRetainCount(vm)) // 3 - captures the reference once.
let biding_2 = vm.getBinding(keyPath: \.value)
print(CFGetRetainCount(vm)) // 5 🐞 - captures the reference twice.

You have similar code here:

https://github.com/swiftwebui/SwiftWebUI/blob/develop/Sources/SwiftWebUI/Properties/BindableObject.swift#L28

I suspect that they do use [unowned self] in one of the closures because the other closure is already known to capture the reference and it's not needed to do it twice. I think in case of the custom _Binding type from the example I would put it into the getter closure because it should be destroyed at first (I assume the top to bottom deallocation order here).

I want to write a SwiftKitUI using the system's UIKit and AppKit support for the low version. But I don't know how to write it. I don't know if I can read it according to the source code of SwiftWebUI.

Hi,

I am really impressed with the framework! I tested some syntaxes and they work flawlessly.

However I am wondering if I can really use for publishing my personal website this way...

How can I host the resulting SwiftWebUI binary to e.g. WordPress or AWS?

I am asking this because I see that Wordpress requires HTML files (which I could not find inside the project) and AWS offers no MacOS instances (??)

Hi,

I was thinking if we could achieve something like static web page result. As a product generated after build/run in the Xcode. What do you think?

If you think it is possible I am more than happy to help :) Would need your help to direct me where to look, focus at.

Cheers, Shial

HStack {
                Text("\(index)")
                Spacer()
                Button(action: {
                    self.index += 1
                }) {
                    Text("Cilie Me")
                }
            }

Text and Button not in Web Content Left And Right .Now in all Left Offset

To repeat the disclaimer: This is a toy project! Do not use it for production. Use it to learn more about SwiftUI and its inner workings.

No, make it production-ready 😂😂😂😂

No seriously, I need this in my life after a decade of HTML/CSS/JS 😭 I hope this project brings new perspective to the ecosystem.

Cheers, and thank you for putting together this project.

What the title says. There are few !important in the CSS to hack-override SemanticUI styles. Those just need to be qualified more specific so they take preferences (e.g. by adding our own classes to the the style).

I create subview Label (because is absent from here)

struct Label: View {

    private let title: String
    private let systemImage: String

    init(_ title: String, systemImage: String) {
        self.title = title
        self.systemImage = systemImage
    }

    var body: some View {
        HStack {
            Text(title)
            Image(systemName: systemImage)
        }
    }
}

but have got error: Type '() -> Label' cannot conform to 'View' while try to put it in tabItem :(

I use this syntax :)

         NewsListView().tabItem {
               Label("Новости", systemImage: "newspaper") 
         }

but when I change syntax to: NewsListView().tabItem(Label("....")) all working now.... hmm

Previously conditionals had to have a trailing "else {...}" at the end because of lack of optional support from the View protocol. This fix will introduce View optionals and make the behavior more like SwiftUI's View.

Note: I had to add an optional check inside ComponentReflection.swift, I'm not 100% sure of the inner workings of this file but this doesn't seem to be causing any conflicts.

Hello, I have taken a recent interest in this project and have written a PR for issue #42 The idea of HTMLStylePatching node is to serve as a "container" to hold style patches, whenever we call the .patch function it will automatically hook into an existing patching node, or create a new one if it doesn't already exist.

The sample code presented in #42 works properly now, however, I am still having minor issues chaining multiple shadows on the same view (CSS shadow blending issues).

Lastly, I would like to note that my implementation in BackgroundModifier.swift isn't as clean as I wish (I had to copy the style switch from the HTML node). Perhaps there is a better way to do this.

Hi, I have the following code:

struct MainPage: View {
    var body: some View {
        return VStack {
            OrderHistory(previousOrders: previousOrders)
        } .background(.black, cornerRadius: nil)
            .padding(0)
            .relativeWidth(1)
            .relativeHeight(1)
    }
}

Now the page looks like that: How can I access the page color? I want the full black page.

Even though the thing probably works fine, it gives a warning on Swift 5.2 for good reasons.

This should grab the pointer to the actual view storage higher in the flow and pass it down.

EnvironmentObject value passed in view hierarchy changed on server callback crashes serwer.

error: warning: couldn't get required object pointer (substituting NULL): Couldn't load 'self' because its value couldn't be evaluated

error: Execution was interrupted, reason: EXC_BAD_ACCESS (code=1, address=0xfffffffffffffffd).

Inside

guard let box = slot.pointee.value as? StateValueBox else {
        fatalError(
          "@EnvironmentObject value is pointing to a different box type!")
      }

To reproduce fetch changes from tag #52 https://github.com/shial4/SWUI-NextUp/tree/%2352

1. build & run.
2. Select sign in tab
3. Enter credentials ([email protected], test123456)

Click continue -> nothing will happen at first click (no clue why) wait like 5 seconds and click it second time. View will change and serwer will crash.
