The contentMode property of the image view is used to determine how to display the image properly. Use the isHighlighted property to check whether the imageview is in highlighted state. This attribute is used to change the initial state of imageview to highlighted. To set this attribute programmatically, we can use highlightedImage or highlightedAnimationImages property.

It means that the image can be used for universal devices, including IPad and iPhone. The above image also shows Universal mentioned below the image. In iOS applications, there three categories of images that can be added to the project based on the dimensions, I.e., 1X, 2X, and 3X. The following image shows an imageset where we can drop the image we want from the local device. Here, we need to drag and drop the image files from the local device to the new image set in the Xcode. This will create the New Image Set (folder in the assets). To add a new imageset in the assets, right-click in the left pane below the AppIcon and choose New ImageSet from the list. Initially, there are no assets in the Xcode. This folder contains all the assets that are being used in the project, including the app icon.
