Uiviewcontroller Uiimageview Nsstring

This document contains code for an iOS app written in Swift that uses Alamofire and SwiftyJSON to make API requests to Instagram and download a user's profile image. It defines a ViewController class with methods to make the API requests, parse the response, and display the image in an image view. When a button is tapped, it downloads the profile image URL from Instagram and makes a second request to actually download the image data and display it.
