Use the color picker and images list to set your colors and images directly in the code Xcode has the ability to embed colors and images directly in code. This is done with the help of Color Literals and Image Literals.  Color Literal  A color literal allows you to select colors using a color picker directly from your code. You can either select a color or type in the HEX code. You can also set the opacity. Note : Color literals are great for static colors. For colors that adapt to dark mode, I suggest using colors in the Assets Catalog. Code: let color0 = Color( #colorLiteral ( red : 0.5568627715 , green: 0.3529411852 , blue: 0.9686274529 , alpha: 1 )) ; let color1 = Color( #colorLiteral ( red : 0.3647058904 , green: 0.06666667014 , blue: 0.9686274529 , alpha: 1 )) ; .. Image Literal   Similar to color literals, image literals opens up a GUI from where you can select all the images in your Assets Catalog. You can download free images from https://www.freepik.com/. var...

How to use shapes like circle, ellipse, capsule, rectangle and rounded rectangle With SwiftUI, you get access to five built-in shapes which are circle, ellipse, rectangle, rounded rectangle and capsule. Shapes vs Stacks  Unlike stacks, shapes take the maximum space.  To color them, you use fill and foregroundColor instead of background. They're great for clipping content and setting a border style. Circle   The Circle allows you to draw a perfect circular shape. The circular shape will have a diameter that's equal to the smaller number between width and height. Circle () .stroke (Color.black, lineWidth: 2) .frame (width: 44, height: 44) .. Ellipse   The Ellipse is like a circle, but without the perfect aspect ratio 1:1. When the width and height are different, it'll fill the space and distort itself. Ellipse () .stroke(Color .black , lineWidth: 2 ) .frame( width : 44 , height: 88 ) .. Rectangle   While most elements in SwiftUI such...

Adding Images to Your Xcode Project  Import images into your project, manage their appearances and variations and load them at runtime. Create a New Image Set An image set represents one image that you intend to load at runtime. Each image set contains multiple variations of a single image that you customize to support different device characteristics.  If you have multiple images in your app, you need to create an image set for each image. To create an image set, generate an image asset outside of Xcode, then import it into an asset catalog. The system converts the image format into the most appropriate representation when you build the project. In the Project navigator, select an asset catalog: a file with a .xcassets file extension. Drag an image from the Finder to the outline view . A new image set appears in the outline view, and the image asset appears in a well in the detail area. Rename : Double-click the image set name in the outline view to rename the image set with...

Design your layout using the inspector, insert menu and modifiers In this tutorial, we'll take a quick look at how to create a simple layout by only using the visual editing tools and without touching the code. Insert Menu  The Insert Menu ( Cmd  + Shift +  L ) is great for bringing new elements.  You can find a long list of all the controls available in iOS such as button, color picker, date picket, etc.  You can drag and drop an item from the Insert Menu to the Preview or the code.
