Unwrapping Optionals in Swift
//Here’s an example of how you might use an if let statement to safely unwrap an optional:
if let unwrappedOptional = someOptional {
// Use unwrappedOptional here
} else {
// Handle the case where someOptional is nil
}
//And here’s an example of how you might use a guard statement to safely unwrap an optional:
guard let unwrappedOptional = someOptional else {
// Handle the case where someOptional is nil
return
}
