Bulk tag tasks?

On iOS, how can you select multiple tasks and tag them all at once? I can only see how to do this on macOS.

You need to run 'Bulk Actions' by swiping (if settings are set to open bulk actions page) or tapping 3-dot button on top right and choose 'Bulk Actions'. On that page, you can select multiple tasks and run quick actions. Thanks!

So I need to make a specific quick action for each tag I might want to toggle?

Thanks for the details. As you said, currently context menu tag option is not available on bulk actions page. Currently it's only available when you long tap a single task on iOS. I'll check and will see what can be done. Meanwhile, you need to use quick actions to set up tags. Prompt tags would be helpful to choose between multiple tags. Thanks!
