Issue #932
Add Share extension and Action extension respectively in Xcode. We can use the same code to both extension
SwiftUI
I usually make a ShareView in SwiftUI with ShareViewModel to control the logic
struct ShareView: View {
@ObservedObject var vm: ShareViewModel
var body: some View {
NavigationStack(path: $vm.routes) {
List {}
}
}
}
In ShareViewController, we can just conform to UIViewController and add our SwiftUI view as child view controller
let vm = ShareViewModel()
let hostingController = UIHostingController(rootView: ShareView(vm: vm)
addChild(hostingController)
view.addSubview(hostingController.view)
hostingController.didMove(toParent: self)
hostingController.view.constrainEdges(to: view)
We can use this same ShareViewController for both Share and Action extension, so add it to both targets.
Info.plist
In Share extension Info.plist, we can replace the default NSExtensionActivationRule of TRUEPREDICATE with the below.
I also use code instead of storyboard, so I use NSExtensionPrincipalClass instead of MainInterface

Icon
For Action extension, we need an icon to show in system Share dialog. We can add new App Icon to Media asset catalog
Note that we need to specify this AppIcon in Primary App Icon Set Name
