Last active Aug 22, 2022
For a macOS app, if you want an action in both the main menu and the UI, it's quite boilerplaty. You need to synchronize some value with @FocusedValue. What if we had something like this?
View SwiftUI Placeholder idea.swift
struct CameraCommands: Commands {
var body: some Commands {
CommandGroup(replacing: .newItem) {
// This menu item will be enabled when the key view has a button with `.command(.takePhoto)`. The action logic is implemented in the button.
Placeholder("Take Photo", id: .takePhoto)
// Alternatively, it could be:
// Button("Take Photo") {}
// .placeholder(.takePhoto)
View Collection+safe.swift
extension Collection {
Returns the element at the given index if any, otherwise `nil`.
guard let element = array[position] else {
View NSView+shake.swift
extension NSView {
Shake the view.
- Note: It will do nothing if the user has enabled the “Reduce motion” accessibility preference.
func shake(
duration: TimeInterval = 0.3,
direction: NSUserInterfaceLayoutOrientation,
moveAmount: Double = 5
View Sequence+splittingEvenly.swift
extension Collection where Element: Comparable {
Returns the index of the first occurrence of the lowest value in the collection.
[4, 2, 3, 2, 5].firstIndexOfMinElement()
//=> 1
func firstIndexOfMinElement() -> Index? {
View UnexpectedNilError.swift
// Using `LocalizedError` here as the `.localizedDescription` for `Error` is often missing in places like an alert and Crashlytics/Sentry.
struct UnexpectedNilError: LocalizedError {
let message: String?
let file: String
let line: Int
_ message: String?,
file: String = #fileID,
line: Int = #line

Ideas for machine learning usage in my apps

Machine learning for my apps

I'm trying to think of ways I could use machine learning to enhance my apps. Feedback wanted!

You can find my apps here.


  • Natural language processing to parse a new event title, like Fantastical.
sindresorhus / IdentifiableByHashable.swift
Created Mar 10, 2021
Make a type `Identifiable` based on its `Hashable` hash value.
View IdentifiableByHashable.swift
Make a type `Identifiable` based on its `Hashable` hash value.
This can be useful when all the properties are required to represent its identifier.
struct Item: Hashable, IdentifiableByHashable {
let title: String
var message: String?
