在Xcode中快速拖动UIImage

Question

I know it is possible to directly drag UIImage in Swift code, which looks like this

But somehow I am unable to get it working.

I tried to drag the image@3x.png from resources to code but the dragged image points to some other image, need to know how to get these image literals working.

Answer 1

you must have the image in your Assets.xcassets folder. Then after typing Image Literal autocomplete double click the icon and select your image from the collection. If you have too many images, and you still want to use the Image literals, then comment the ImageLiteral line, and write the exact name into the init of #imageLiteral, like this : // #imageLiteral(resourceName: "NameOfYOurPicture") then uncomment it, and you will have your image there
