Implementing Gradient UIView using Extension

Before working on gradient UIView, we need to follow below steps.

1. Create New Projects:

First of all we need to create a new project where you will integrate gradient UIView.

2. Add UIView:

After that we need to add a UIView either programatically or using Storyboard.

3. Create UIView Extension for Gradient:

The extension is a great concept in swift you can add your function is already predefined classes in swift  like String, UIView, UIColor etc. A while creating an extension you can write it anywhere in your project. To create a gradient extension you have to create an extension of UIView class. The main benefit of extension is that it will reduce many of your code lines like you have to use the gradient 5 times in your project so you have to write the same code 5 times in your project while creating an extension you have to write it only once it will also save the application memory.

Example to create an extension.

Above code is helpful to create gradient UIView.

4. Use Extension:

We need to call extension UIView from viewDidLoad()
