Swift

What is Swift, really?

Want to build an iPhone app that feels truly native? Swift is your only real option. Apple created it to replace the painful Objective-C, and the result is a language that is genuinely pleasant to write. SwiftUI makes building iOS interfaces faster than ever before.

Why learn it in 2026?

iOS users spend more money than Android users globally. App developers know this. Indian iOS developer salaries are 30-50% higher than equivalent Android roles, especially in product companies and startups.

What it looks like

// SwiftUI button
import SwiftUI

struct ContentView: View {
    var body: some View {
        Button("Tap Me") {
            print("Hello iOS!")
        }
        .foregroundColor(.blue)
    }
}
