1. SwiftUI 2. VisionOS 3. Profit?!

Drawn in a monochrome manga style with line and tone, a robotic left hand holds a shiny sphere aloft, reflecting the decapitated robot in a study just like Escher's.

Title page of textbook reads: immersive linear algebra by J. Ström, K. Åström, and T. Akenine-Möller v1.1. ISBN: 978-91-637-9354-7 The world's first linear algebra book with fully interactive figures. The middle of the image is an interactive, rotating figure where three vectors emanate from a yellow point. Their ends describe an orange triangle, and dotted lines extending from each vector eventually intersect a blue plane and describe a different grey triangle. Like most of the illustrations in the book, the user can adjust the vectors dynamically and see the rest of the diagram update.
The white witch is certainly there, looking pensive and cross. That's likely Edmund by her side, though all but his hair is concealed by a white band across the bottom of the book with a barcode and price.
Screenshot of Xcode comparing two versions of the same file. Revised sections are highlighted with a different colour in each version, and elegant gradients and bridges with radiused corners connect between the two.
Screen recording of simple habit tracking app for visionOS. Content is in a rectangular window, floating in the built-in living room environment of the simulator. Features include logging of completion dates, identification of streaks (highlighting records which are part of a streak in bold, and streaks greater than four records in bold and orange), and the ability to add new habits and delete them.
Better Rest app which takes inputs of preferred wake-up time, desired amount of sleep, and daily coffee intake, and outputs a suggested bedtime. Makes use of the Date type and machine learning behind the scenes. All presented in the visionOS simulator, in the setting of a kitchen at night time.
A one-line function which accepts an optional array of integers, and returns a random member if there's actually an array of ints rather than nil. If it is nil, you just get a random number from one to one hundred. Code to follow: func rando(_ integers: [Int]?) -> Int { integers?.randomElement() ?? Int.random(in: 1...100)}
Employee Struct with vacation function, customised to relate to Severance, with an employee named Helly R who says "So long, Milchick!" when she takes annual leave.
Solution to Checkpoint 5 in 100 Days of SwiftUI - using closures to sort an array of Ints (extracting only multiples of two, putting them in order, and printing each on a new line as a 'lucky number'). Code is as follows: let luckyNumbers = [7, 4, 38, 21, 16, 15, 12, 33, 31, 49] luckyNumbers .filter { $0.isMultiple(of: 2) } .sorted().map { (number: Int) -> String in return String(number) + " is a lucky number"} .forEach { print($0) }
FizzBuzz, an introductory coding exercise. Code as follows... for i in 1...100{ let fizz = i%3 == 0 let buzz = i%5 == 0 if fizz && buzz { print("FizzBuzz") } else if fizz { print("Fizz") } else if buzz { print("Buzz") } else { print(i) } }
