What is optional chaining in Swift?
An example of an AI chatbot conversation about optional chaining in Swift programming.
What is optional chaining in Swift?
Optional chaining is a way to safely access properties and methods on optional values in Swift.
Can you give me an example of how it works?
Sure! If you have an optional object, you can use ?. to call a method or access a property without unwrapping it first.
What happens if the optional is nil?
If the optional is nil, the entire expression returns nil instead of causing a runtime error.
Are there any performance implications of using optional chaining?
Generally, optional chaining is efficient, but excessive use in performance-critical code should be evaluated.
