Thanks for the review, Hafiz! Marking it as draft to address feedback about using userdefaults in https://github.com/woocommerce/woocommerce-ios/pull/12287.

I tried looking into Core to see if there is a built-in feature for this. The closest I found is the "Favorite" feature:

Thanks for the input, @hafizrahman!

Yes, I took a look at this before starting work and learned that this feature in core is used to feature the product to the users (customers).

Our "Favorite product" feature's goal is to allow merchants to favorite products for easy management.

They are different features and our feature will be mobile only (with no backend support from core) at least for now.

👋 again @hafizrahman,

I have revisited this PR and pushed changes to,

• Stop using user defaults to store favorite product information.
• Use GeneralStoreSettings and AppSettingsStore to store the favorite products information.
• Add unit tests.

Please take another look at the PR when you can. Thank you!
