How to Use Trailing Closures

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

func perform(task: () -> Void) {
    task()
}

perform {
    print("Running")
}

Notes

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