How to have Firebase automatically delete values older than 30 minutes

Question

I have a Swift/iOS application that creates/holds data something like this:

buyer_name: \"john@gmail.com\"
seller_name: \"tom@gmail.com\"
price: \"20.00\"

Answer 1

You can use Cloud Functions for Firebase and set up a cron job that runs, say, every five minutes and checks for timestamps older than 30 minutes.

As Will commented, that blog post is useful to learn about scheduling Cloud Functions. Here are some other useful resources to get you started:
