Description

Declaring a variable as optional clearly signals that it may not hold a valid value and could be nil. Force-unwrapping bypasses that safety and will cause a runtime crash if the value is actually nil. Even if you check for nil first, relying on force-unwrapping is still discouraged because it undermines the intent of optionals. A safer and more maintainable approach is to use optional binding or optional chaining to handle values gracefully.

Non-Compliant Code Examples

var greeting: String?

// ...
println( \(greeting!))  // Noncompliant; could cause a runtime error

if greeting != nil {
  println( \(greeting!))  // Noncompliant; better but still not great
}

Compliant Code Examples

var greeting: String?

// ...
if let howdy = greeting {
  println(howdy)
}
