Using the VIP pattern (Clean Swift) with SwiftUI

This is a small example project to demonstrate how to use the VIP pattern with SwiftUI. It consists of three branches:

• main → a basic example of a view with two buttons and a label. Tapping the buttons increments or decrements the value of the label.
• variations/subviews → a further development of the main branch, moving the view with the buttons and the label to a subview.
• variations/subviews-asynchronous-task → a further development of the variations/subviews branch, adding a second subview which displays the result of a decoded response from a network call and has a reload button. E.g. when incrementing the counter and then tapping the reload button, it demonstrates that a state of one view will be unaffected when interacting with another subview within the same scene.
