Take a look at AlanQuatermain -s SwiftUIShareSheetDemo

In a nutshell it looks like this:

@State private var showShareSheet = false
@State public var sharedItems : [Any] = []

Button(action: {
    self.sharedItems = [UIImage(systemName: "house")!]
    self.showShareSheet = true
}) {
    Text("Share")
}.sheet(isPresented: $showShareSheet) {
    ShareSheet(activityItems: self.sharedItems)
}

struct ShareSheet: UIViewControllerRepresentable {
    typealias Callback = (_ activityType: UIActivity.ActivityType?, _ completed: Bool, _ returnedItems: [Any]?, _ error: Error?) -> Void

    let activityItems: [Any]
    let applicationActivities: [UIActivity]? = nil
    let excludedActivityTypes: [UIActivity.ActivityType]? = nil
    let callback: Callback? = nil

    func makeUIViewController(context: Context) -> UIActivityViewController {
        let controller = UIActivityViewController(
            activityItems: activityItems,
            applicationActivities: applicationActivities)
        controller.excludedActivityTypes = excludedActivityTypes
        controller.completionWithItemsHandler = callback
        return controller
    }

    func updateUIViewController(_ uiViewController: UIActivityViewController, context: Context) {
        // nothing to do here
    }
}
