In "A Letter of Advice to a Young Poet" from 1721, Jonathan Swift remarked that a commonplace book is something that “a provident poet cannot subsist without, for this proverbial reason, that great wits have short memories”.

If you have large numbers, Swift lets you use underscores as thousands separators – they don’t change the number, but they do make it easier to read.

What’s a Stack? A stack is a collection of SwiftUI views that are grouped together. You can use 3 kinds of stacks with SwiftUI: VStack, a vertical stack, which shows views in a top-to-bottom list HStack, a horizontal stack, which shows views in a left-to-right list ZStack, a depth-based stack, which shows views in a back-to-front list Here’s a visual example: <img src="https://learnappmaking.com/wp-content/uploads/2020/08/swiftui-stacks-diagram.jpg" width="1125" height="450" alt="Diagram of HStack, VStack, ZStack in SwiftUI"> You can compare stacks in SwiftUI with UIStackView in UIKit. Stacks are static, so they’re different from List and table views, for example. Like other SwiftUI views, stacks can contain a maximum of 10 subviews. You can, of course, combine VStacks, HStacks and ZStacks to create complex User Interfaces.

As such, the following two statements are equivalent:

Executing AppleScript in a Mac app on macOS Mojave and dealing with AppleEvent sandboxing

Optimizing Swift build times

And because it’s built to take full advantage of iPad, it’s a first-of-its-kind learning experience.
