SwiftHow to Work with Arrays
Create, update, and iterate arrays safely.
Steps
- Paste the code into a Swift file or playground.
- Run it once to verify the output.
- Adjust the inputs to match your use case.
Copy and paste
import Foundation
var fruits = ["Apple", "Banana"]
fruits.append("Cherry")
for fruit in fruits {
print(fruit)
}Notes
- Keep functions small and focused for reuse.
- Prefer safe APIs like optionals and guards.
