README
JGProgressHUD-SwiftUI
---------------
This is a lightweight and easy-to-use SwiftUI wrapper for [JGProgressHUD](https://github.com/JonasGessner/JGProgressHUD), giving you access to the large and proven feature set of JGProgressHUD. Supports iOS, macCatalyst and tvOS 14.0+.

[](https://swift.org/package-manager/)

Installation
--------------
JGProgressHUD-SwiftUI can only be used with the Swift Package Manager.
In Xcode, use the menu File > Swift Packages > Add Package Dependency... and enter the package URL `https://github.com/JonasGessner/JGProgressHUD-SwiftUI.git`.
Usage
---------------
This package builds on top of the UIKit-based [JGProgressHUD](https://github.com/JonasGessner/JGProgressHUD) and provides a trivial way of showing HUDs in SwiftUI code.
You use the view `JGProgressHUDPresenter` as a canvas, which can display HUDs over its contents. Generally you want to use a single `JGProgressHUDPresenter` view as the root view of your application, such that full screen HUDs can be displayed.
To show a HUD from any contained view, define the environment object of type `JGProgressHUDCoordinator` in your view struct. This object is automatically available in the environment via `JGProgressHUDPresenter`. Call its `showHUD(constructor:handleExistingHUD:)` method, providing a `constructor` closure that returns the HUD to show. The returned HUD will be shown automatically, hence you do not need to call the `show()` method on the HUD. You may already schedule the HUD to disappear using the `dismiss(afterDelay:)` method.
The `handleExistingHUD` closure is only called in case a HUD is already presented. You can, for example, dismiss the current HUD and return `true` to continue showing the new HUD. By returning `false` (default), you prevent the new HUD from being shown.
You may furthermore access, modify or dismiss a HUD that is already presented by accessing the `presentedHUD` property of the `JGProgressHUDCoordinator` environment object. After a HUD dismisses, this property is automatically reset to `nil`.
Example
---------------
Also see the [Example Project](https://github.com/JonasGessner/JGProgressHUD-SwiftUI/tree/main/Example).
```swift
import SwiftUI
import JGProgressHUD_SwiftUI
struct NavigationBody: View {
// This environment object is automatically set by JGProgressHUDPresenter.
@EnvironmentObject var hudCoordinator: JGProgressHUDCoordinator
var body: some View {
Button("Press Me") {
// Simply call showHUD and return your HUD!
hudCoordinator.showHUD {
let hud = JGProgressHUD()
hud.textLabel.text = "Hello!"
hud.dismiss(afterDelay: 3)
return hud
}
}
}
}
struct ContentView: View {
var body: some View {
// This presenter can present a fullscreen HUD.
JGProgressHUDPresenter {
NavigationView {
NavigationBody()
}
}
}
}
```
Requirements
------------
- Deployment target of iOS/tvOS/macCatalyst 14.0 or higher.
