Disable Mouse Scaling on macOS via Terminal

Adopted from:

Check the current value of scaling in user defaults:

~ defaults read .GlobalPreferences

This will display a hidden preference setting that you can change by altering the number at the end. If the mouse acceleration feature is enabled, the above command should display a value between 0 and 3. This is the value that is altered when you move the ‘Tracking Speed’ slider

Disable mouse acceleration:

Video: Meet async/await in Swift

With Swift concurrency, functions, initializers, read-only properties, and for-loops can all be marked async. Property getters can also throw.

Notes for working with Xcode VIM mode

Xcode VIM

Learning VIM in Xcode comes with its own set of challenges and limitations, but there is enough there for you to give your mousing hand a break and master the keyboard.

A limited set of commands are available in Xcode, and this document attempts help ease the learning curve of using VIM in Xcode by providing a handy reference as well as what I find works for me in practice.

NOTE: Commands are case-sensitive. A command of N means pressing shift + n on the keyboard.

This document is a work in progress! Leave a comment if you would like to see a change.

Swift UI State Management

Swift UI State Management

Storing state for Child View Models

SwiftUI is all about state, and maintaining that state can be rather difficult when you have more than a few properties stored as @State for your view. It is common practice to use a view model to store the state outside of the view, since our views are constantly recreated as our state changes. Keeping what state you want in memory can provide a challenge, much more so than it may seem at first glance.

With SwiftUI 2, using @StateObject will keep a view model from being recreated with each rendering of a view's body. If the parent view is creating the view model, and then passing that down to the child view, that view model will also be recreated with each rendering of that parent view body.

struct ParentView: View {
  var body: some View {
