Solved: add border to button

Sure, let’s dive into this!

Swifty, stylish, and functional design often leads us to craft specific UI elements on an iOS app. One such common element is a button with a border. A button may seem simple, yet it holds considerable power in setting the tone of the user journey.

To provide an enhanced user experience, a button must be appealing and inviting, indicating a clear path to interaction. This is where the aesthetic angle comes into play. And, one of the classic ways to do this is by adding a border to a button. Here’s how you can do this using Swift.

Adding Border to A Button in Swift

The task of adding a border to a button in iOS can be accomplished quite simply by manipulating the ‘layer’ property of UIButton. The `layer` property is of type `CALayer`, a powerful class that allows you to manipulate the visual content of UIView and its subclasses, such as UIButton.

let button = UIButton()
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.black.cgColor

In the above snippet, firstly, we’ve created an instance of UIButton. Then, we’ve set the `borderWidth` to 1.0, indicating the width of our border. After this, we’ve selected the color for our border with `borderColor`. Here, it’s black.

Step-by-Step Explanation of the Code

To add a border to a button, we need to access its CALayer and manipulate its properties. Here are the steps to do this:

• Create a button through UIButton(), where UIButton is a view that is inherently touchable, which executes a function when the user interacts with it.
• Set the `borderWidth` to define the thickness of the border. This is a CGFloat value that defaults to 0.0, meaning no border. As you increase this value, the border becomes thicker.
• Choose your `borderColor`. Remember to convert the UIColor to a CGColor as the `borderColor` property of a CALayer expects a CGColor.

So, with these simple lines of code, you can offer your users an appealing and intuitive path to interaction in no time!

Further Customization and Libraries

Swift allows further customization. For example, `cornerRadius` can be manipulated to enhance the rounded corners of a button leading to a much softer, friendlier design.

You can also use third-party libraries like `CosmicMind/Material`, which allows creating an expressive, flexible UI with intricate animations and transitions. However, use third-party libraries wisely as they add to the app’s size.

In conclusion, an appealing and intuitive design is crucial for a successful user interaction experience and Swift gives you many exciting customization options to achieve this objective. Design smartly!
