swift image

//Make sure the image you want to show is imported into your "Assets.xcassets" file.

Image("dog")

how to add an image in swift

//The first step is to rename the image you want to add into your xcode project
//Then, drag the picture to the Assets.xcassests folder.
//Next, use the Image struct and init(name) to display the picture

//For example, if your picture in the Assets.xcassests folder is named daddy, then to get the picture, use

Image("daddy")

//There are more modifiers to the Image but that will not be discussed here
