Buttons are used in SwiftUI to provide a mechanism for a user to initiate an
interaction with an app. This article shows how to customise buttons in SwiftUI.
SwiftUI provides a default style for buttons, but this can be modified in many ways
and it can be helpful to provide a common style for buttons in your app.
Animations can be used to give an App character and help bring the App to life. They
can be used to explain how an app works, enhance navigation between screens or simply
direct a user's attention. In this article we show how to animate the change of a
shape from a triangle to a square or a circle.
Images can be used in a variety of ways to create engaging and entertaining iOS Apps.
Images can be used as backgrounds, icons, buttons and to improve content. This article
shows how to add an image in Xcode and goes through some of the display modifiers
to use to control the image display.
SwiftUI uses a declarative approach to creating the User Interface. This means the
code is written to state what the user interface should look like. Stacks provide a
mechanism to define the layout arrangement of multiple views in a SwiftUI app.
The Fibonacci sequence is a series of numbers where each number in the sequence is
the sum of the preceding two numbers, starting with 0 and 1. It is natural to
consider a recursive function to calculate a subset of the Fibonacci sequence, but
this may not be the most efficient mechanism.
