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?
View Image++.swift
extension Image {
Image(nsImageNamed: NSImage.addTemplateName)
- Note: The `size` parameter is there as resizing in SwiftUI creates a blurry image. Seems like a bug:
Image(nsImageNamed: NSImage.addTemplateName)

Pure ESM package

The package linked to from here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.

sindresorhus / NativeButton.swift
Created Oct 11, 2019
Example of using NSButton in SwiftUI to access missing features like `keyEquivalent` (for example, to make the button the default and highlighted). Stack Overflow answer:
View NativeButton.swift
struct ContentView: View {
var body: some View {
NativeButton("Submit", keyEquivalent: .return) {
// Some action
