Key concepts:

  1. You can visually edit the SwiftUI code using the attributes inspector.
  2. Cmd + D will duplicate elements (a bit like Figma).
  3. I need a M1 Mac!
  4. Padding is the space around an element.
  5. Spacing is the space between elements inside a container (like VStack).
  6. Ctrl + Option + click inside the visual editor will bring up the attribute inspector as a pop over.
  7. Cmd + Shift + L shows the Library from which you can choose what elements to add.

Day 59: 6 May 2021

Today: Worked through lessons 3 to 6 of SwiftUI for iOS 14. Also started reading Building Mobile Apps at Scale by Gergely Orosz

Thoughts: I can see what the rage is all about for SwiftUI.

Key concepts:

  1. Cmd + N create new file from selecting a template.

  2. Xcode can now create a group and a folder from selection. Used to be "virtual" folders in the project but not on disk.

  3. Using SF Symbol icons is as easy as: Image(systemName: "sfsymbol.icon.name")

  4. Creating a side bar:

     List {
 	...
 }
 .listStyle(SidebarListStyle())

  5. Creating a navigation view (legacy navigation bar + vc)

     NavigationView {
 	...
 	NavigationLink(destination: someOtherView()) {
 		...
 	}
 }
 .navigationTitle("Screen name")

  6. Conditional code for iOS & iPadOS vs macOS

     #if os(iOS)
 	...
 #else
 	// macOS code
 #endif

  7. On macOS you can control the window / frame sizing

     .frame(minWidth: 800, minHeight: 600)

  8. Toolbar allows you to place bar button items on the top or bottom. Can be placed inside a NavigationView and can contain multiple ToolbarItems
