Save Settings Delegation
Tinder Firestore Swipe and Match
In order to view this lesson, you must purchase this course.
In this lesson, we'll go over how we can utilize the persisted settings data from Firestore to filter out the cards inside of the <b>HomeController</b> components of our application. The first thing we'll do is to make sure our Firestore query includes two fields of less than and greater than. Next we'll have to fetch our currently logged in user to see what these min/max values are. Finally, we'll apply some custom delegation to invoke our user fetching after our settings is saved inside of <b>SettingsController</b>.
