"42!"

Kase 4.2 will be realizing a major part of my dream that started 10 years ago...

A number is usualy not just a number. It is often a quantity associated with a unit. Without the unit, it is a figure floating in a vague dimension. But when paired with a unit, the number becomes a measurement carrying a concrete value.

Kase 4.2 helps you keep track of numbers with units.

Open letter to all numbers

4 = 4.0 + 0.1

Kase 4.0 was a huge update. It was so big that compiling the list of changes was almost as big a task as making the app itself...

Inevitably, bugs got in. Especially when we are supporting three major releases of iOS/iPadOS (15, 16, and 17), and Apple likes changing things around with little to no documentations... (e.g. SF Symbols names, hi, what are you now?[^sfs])

NSUserDefaults → UserDefaults

In the beginning, when Cocoa was hot (circa 2001), there was already NSUserDefaults, a thoughtful API for the seemingly simple task of persisting preference settings.

Swift (since 2014) gave it a cleaner name (UserDefaults, without the NS prefix), but it also created new expectations that the plain old class was not delivering:

  • strong type checking
  • easy value types usage
  • modern Swiftness, etc.

This is where Swiftified UsersDefaults libraries come in. Here we look at a few of them:

  1. SwiftyUserDefaults: "Modern Swift API for NSUserDefaults"
  2. Defaults: "Swifty and modern UserDefaults"
  3. Foil: "A lightweight property wrapper for UserDefaults done right"

Kase 3 was designed for iOS1 13, and it has been updated numerous times to work well with later releases of iOS 13 and 14.

Kase 4 will be the recommended version of Kase for iOS 15 and greater. This post will document how the older Kase 3 works under iOS 15.
