M1L5 : Creating Data via Xcode

In Lesson 5 of Module 1 of the CWC+ iOS Database Course, Micah shows us how to use Xcode to add data to our Firestore database.

Having previously set-up Firebase, and ensuring we’ve added GoogleService-Info.plist to our Xcode project, we can use the following commands.

Get access to our Firestore database:

let db = Firestore.firestore()

Create a new collection, or get a reference to an existing collection:

let myCollection = db.collection("collection-name")

If the “collection-name” collection doesn’t exist, it will be created.

Create a new document in the collection:

myCollection.document("myDocument")
    .setData([
        "key1":"value1",
        "key2":"value2
    ])

If we omit the document reference, re: myCollection.document(), then a unique identifier will be auto-generated. Shorthand for this would be:

let myDocument = myCollection.addDocument(data: ["key1":"value1", "key2":"value2])

So far, so good!
