KaleidosBlog TechnoVision. Swift image from url: How to load UIImage from url In this tutorial you'll see through an example how to load image from url using Swift.
Select the view controller in the storyboard and open the Connections Inspector on the right. Connect the imageView outlet to the image view in the View Controller scene. Before we move on, we need to configure the image view. With the user interface in place, we can focus on downloading an image and displaying it in the image view.
When it's appropriate for an application to download remote resources, such as images, differs from application to application. We download an image in the view controller's viewDidLoad method, but this is usually not what you want. We start by creating a URL object that points to the remote image.
You should not hard code the URL of a remote resource in the project if you can avoid it. Notice that we forced unwrap the result of the initialization. This is an example so we are not focused on safety. I want to show you two strategies to download an image from a remote server. The first strategy is as simple as it gets.
We initialize a Data object by invoking the init contentsOf: initializer. Because the initializer is throwing, we use the try? In the body of the if statement, the view controller uses the Data object to create a UIImage instance. It assigns the UIImage instance to the image property of its image view. That's it. Build and run the application in the simulator to see the result. This looks fine, but there is one important problem.
The image data is fetched synchronously and the operation blocks the main thread. This simply means that the execution of the application is interrupted as long as the image data is being downloaded.
