How to Use @MainActor

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

@MainActor
class ViewModel {
    var title: String = "Loading"

    func update() {
        title = "Ready"
    }
}

Notes

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