SwiftUI exporting or sharing files

Question

I\'m wondering if there is a good way export or share a file through SwiftUI. There doesn\'t seem to be a way to wrap a UIActivityViewController and present it directly. I\'

You can define this function anywhere (preferably in the global scope):

@discardableResult
func share(
    items: [Any],
    excludedActivityTypes: [UIActivity.ActivityType]? = nil
) -> Bool {
    guard let source = UIApplication.shared.windows.last?.rootViewController else {
        return false
    }
    let vc = UIActivityViewController(
        activityItems: items,
        applicationActivities: nil
    )
    vc.excludedActivityTypes = excludedActivityTypes
    vc.popoverPresentationController?.sourceView = source.view
    source.present(vc, animated: true)
    return true
}

You can use this function in a button action, or anywhere else needed:

Button(action: {
    share(items: ["This is some text"])
}) {
    Text("Share")
}
