Firebase Realtime Database uses a NoSQL cloud database to store data. The data stored in it remain available when the app goes offline. It stored data in JSON format.


Let start first with the setup of the Firebase database.

Steps for creating a ToDo app.

Step 1:- First we create a view controller and add table view and bar button item in it.


Step 2:- For the todo data, we create a model. For storing data in the model.

Step 3:- Add the below code over the viewDidLoad method.

Step 4:- We will create an alert containing a text field, from which we get value from the users. We will save this value to our database. We will save hierarchy like inside “Todo” there will be currentDate. And inside the current date, we will save value with the current time.


Put the above code inside the bar button item action.

Step 5:- Now we will fetch data from the database and save it inside our model.

we will call this method from viewDidLoad and from our bar button item action.

Step 6:- This is the final step in which we will load data in our table view.

When you run your app you will see its functionality like this.
