PortalView
A (potentially) cross-platform, declarative and immutable Swift library for building user interfaces.
WARNING!: This is still a work-in-progress, although the minimum features are available to create real world applications the API is still under design and some key optimizations are still missing. Use at your own risk.
TL; DR;
- Declarative API inspired by Elm and React.
- 100% in Swift and decoupled from UIKit which makes it (potentially) cross-platform.
- Uses facebook's Yoga. A cross-platform layout engine that implements Flexbox which is used by ReactNative.
- Leverage the Swift compiler in order to have a strongly type-safe API.
Here is a sneak peak of the API but you can also check this examples or read the library overview to learn more about the main concepts.
enum Message {
case like
case goToDetailScreen
}
let component: Component<Message> = container(
children: [
label(
text: "Hello PortalView!",
style: labelStyleSheet() { base, label in
base.backgroundColor = .white
label.textColor = .red
label.textSize = 12
},
layout: layout() {
$0.flex = flex() {
$0.grow = .one
}
$0.justifyContent = .flexEnd
}
)
button(
properties: properties() {
$0.text = "Tap to like!"
$0.onTap = .like
}
)
button(
properties: properties() {
$0.text = "Tap to got to detail screen"
$0.onTap = .goToDetailScreen
}
)
]
