[feat] "New Folder" option for Mac file dialogs

[begleynk]

Describe the problem

I'm not able to show the native "New Folder" button in Mac file dialogs to let users create a new folder directly in the dialog according to the docs.

I'm building an app where the user has to choose a location for their "project". The project location likely doesn't exist yet, so they'll have to create it. Because they can't create the location inline in the file dialog, they have to jump out of the app, create the directory, come back to the app, and then select it.

Describe the solution you'd like

In Electron, you can pass the createDirectory flag to show a native "New Folder" button in the Mac file dialog (link to relevant docs).

Seems like this is the cleanest solution, and Tauri could expose this option.

Alternatives considered

User can always go outside the app to create the directory.

Additional context

I understand Tauri uses rfd for file dialogs. Maybe this needs to be implemented there first? It seems it's not supported at the moment.

Love what you folks are doing with Tauri! 🎉

This should be the relevant obj-c api: https://developer.apple.com/documentation/appkit/nssavepanel/1532626-cancreatedirectories (as shown in tauri-apps/tauri#6435)

Is there an alternative way to get the "New Folder" button in the meanwhile?

[Nick-Fanelli]

Yeah, has anyone figured anything out yet?

[amrbashir]

As far as I can see in rfd source code, they are using the needed APIs, unfortunately since I don't have access to macOS, I can't investigate further

[amrbashir]

After a second look, seems like rfd are only enabling it for when picking directories, will open a PR later at rfd

[amrbashir]

Opened a PR and since this will require a new version of rfd that we can't update to in v1, will move this issue to plugins-workspace to target v2 instead.

Thanks!
