Identify the error in this Swift code for API integration:

let url = URL(string: "https://api.example.com")
let task = URLSession.shared.dataTask(with: url!) { data, response, error in
  if error != nil {
    print("Failed")
  } else {
    print("Success")
  }
}

AClosure parameters are incorrect

BURL string is invalid

CMissing task.resume() to start the request

DUsing URLSession.shared incorrectly

Step-by-Step Solution

Solution:

Step 1: Check if the data task is started
The code creates the task but never calls task.resume(), so the request never runs.
Step 2: Confirm other parts are correct
The URL is valid, closure parameters match, and URLSession usage is correct.
Final Answer:
Missing task.resume() to start the request -> Option C
Quick Check:
Without resume(), request won't run [OK]

Quick Trick: Always call resume() to start URLSession tasks [OK]

Common Mistakes:

Forgetting to call resume()
Force unwrapping URL without checking
Misnaming closure parameters
