Programming Languages
Swift
Swift is Apple's modern programming language, introduced in 2014. It's designed to be safe, fast, and expressive—making it easier to write correct code while still delivering great performance.
Swift powers all my apps across iOS, iPadOS, macOS, watchOS, and visionOS.
How I Use It
Swift is my primary language. All 13+ of my published apps are written in Swift:
- iOS Apps — Mobile applications with SwiftUI
- macOS Apps — Desktop tools like Simple Takeoff
- SwiftUI — Declarative UI framework for building interfaces
- Swift Data — Apple's persistence framework for storing data
Quick Example
A simple SwiftUI view with a counter:
struct ContentView: View {
@State private var count = 0
var body: some View {
VStack(spacing: 20) {
Text("Count: \(count)")
.font(.largeTitle)
Button("Increment") {
count += 1
}
}
}
}
Key Features
- Type Safety — Compiler catches errors at compile time
- Optionals — Explicit nil handling prevents crashes
- Closures — First-class functions passed like variables
- Async/Await — Modern concurrency syntax
- Protocol-Oriented — Powerful protocols with default implementations
Why I Love It
Swift's readable syntax is easy to write and understand. The compiler is strict but helpful—catching mistakes early. SwiftUI makes building UIs enjoyable. Strong community and excellent Apple documentation.
