How to Create a Class

Steps

1. Paste the code into a Swift file or playground.
2. Run it once to verify the output.
3. Adjust the inputs to match your use case.

Copy and paste

import Foundation

class Counter {
    var value = 0
    func increment() {
        value += 1
    }
}

let counter = Counter()
counter.increment()
print(counter.value)

Notes

• Keep functions small and focused for reuse.
• Prefer safe APIs like optionals and guards.
