This is the simplest kind of radial gradient possible with a gradient composed of 4 colors. Rectangle().fill(radialGradient).frame(width: 380, height: 380).cornerRadius(190) Now that our radial gradient is ready, let's fill the rectangle of the same size (Its width and height same as the gradient's diameter) with it. If there is a mismatch, either some or all parts of some color will be lost or the available space is filled by the color closest to the void If the value of the container is same as the gradient size, you will see all the colors getting equal distribution. As you increase the value of endRadius, the gradient will end a little bit farther from the center. As you increase the value of startRadius, the gradient will begin a little bit away from the center. Between startRadius and endRadius, gradient colors are equally distributed unless the developer has defined the custom color stops. endRadius defines the radius of the gradient and how far it can grow. If the startRadius is zero, the gradient starts exactly at the gradient's center point. StartRadius and endRadius define start and endpoints for the radial gradient. Meaning any container that we put the gradient in, its center will be located at the exact point where the container's center lies. We set the center of the gradient to the objective center. Let radialGradient = RadialGradient(gradient: gradientWithFourColors, center. ![]() Let gradientWithFourColors = Gradient(colors: [ We will create a simple gradient with 4 colors and pass it down to RadialGradient's initializer along with the gradient's center point, start radius and end radius. Please refer to it if you want to know more about all the possible ways of initializing Gradient instance ![]() I already explored them in this blog post. There are various ways of creating an instance Gradient. The radial gradient can be directly created by creating a separate instance of Gradient and passing it to the RadialGradient's initializer above. Creating a radial gradient from the base gradient Let's take a look at them one-by-one and see how to create radial gradients using them. Public init(stops:, center: UnitPoint, startRadius: CGFloat, endRadius: CGFloat)Īll these APIs are responsible for the creation of radial gradients, but some offer flexibility in terms of color stops and the range of colors in a given gradient space. / Creates a radial gradient from a collection of color stops. Public init(colors:, center: UnitPoint, startRadius: CGFloat, endRadius: CGFloat) / Creates a radial gradient from a collection of colors. Public init(gradient: Gradient, center: UnitPoint, startRadius: CGFloat, endRadius: CGFloat) / Creates a radial gradient from a base gradient. RadialGradient in SwiftUI can be created with one of the following APIs, The gradient maps the unit space center point into the bounding rectangle of each shape filled with the gradient. ![]() In today's blog post we are going to talk about how to create and use RadialGradient in SwiftUI.Īpple defines radial gradient as, The gradient applies the color function as the distance from a center point, scaled to fit within the defined start and end radii. If you want to know more about a linear variant of SwiftUI gradients before learning about radial gradients in SwiftUI, please refer to this post This will allow you to write classes like bg-gradient-radial-at-l from-fuchsia-300 via-green-400 to-rose-700, it's hard to tell if that would look awful or amazing, so I recommend using the gradient generator on Hypercolor to see what works and what doesn't.If you haven't read it yet, I wrote about how to create and use linear gradients in SwiftUI in the last blog post.
