Following on from the previous lesson, this short video teaches us the different ways we can delete records (documents) and key-value pairs from our Firebase.
let db = Firestore.firestore()
let myDocument = db.collection("collection-name").document("document-name")
We can use the .updateData modifier to delete individual key-value pairs, thus:
myDocument.updateData([
"key": FieldValue.delete()
])To delete the entire document, we would use the .delete() modifier thus:
myDocument.delete()It’s not adviseable to delete an entire collection from Xcode for some reason, but this can be done through the Firebase web console if necessary.
