[danlfarnell]

Description

When using the share plugin to share a file the following warning is logged to the debug console which warns that the request will fail in the future.

2021-11-15 16:14:54.142159-0500 testing123.iOS[5427:673207] [NSExtension] Extension request contains input items but the extension point does not specify a set of allowed payload classes. The extension point's NSExtensionContext subclass must implement +_allowedItemPayloadClasses. This must return the set of allowed NSExtensionItem payload classes. In future, this request will fail with an error. Extension: <EXConcreteExtension: 0x600000e7f3c0> {id = com.apple.reminders.sharingextension} Items: ( "<NSExtensionItem: 0x60000394f6b0> - userInfo: {\n NSExtensionItemAttachmentsKey = (\n "<NSItemProvider: 0x60000103d810> {types = (\n \"public.plain-text\",\n \"public.file-url\"\n)}"\n );\n "com.apple.UIKit.NSExtensionItemUserInfoIsContentManagedKey" = 0;\n}" )

Steps to Reproduce

1. Create a new app with one button that launches the Share window using the following code.

2.     var fileName = "testFile.txt";
        File.WriteAllText("Testing", fileName);
   
        await Share.RequestAsync(new ShareFileRequest()
        {
            Title = $"Report",
            File = new ShareFile(fileName),
        });
   

3. The warning will be logged to console.

you should add an extension file and use UIActivityViewController extension ARResultController { func presentShareSheet(for url: URL) { let objectsToShare: [Any] = [url] let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil) activityVC.popoverPresentationController?.sourceView = view present(activityVC, animated: true, completion: nil) } }
