Fetch Data Using URLSession In swift (iOS)
Before diving into making requests and mapping data to models first lets understand what is the URLSession?
It’s Swift’s built-in API to make network requests (like fetching data from the internet).
You use it to download JSON, images, or send data to a server.
Think of it as your app’s “internet worker.”
Simple Mental Model to understand the flow of URLSession.
Create a URL - (The address you want to get the data as response)
Create a URLSession Task with - (we will create dataTask as we are hitting the url)
Handle the response (success or error) in a completion handler.
