What are some common mistakes in Swift programming?
Some common mistakes in Swift programming include using force unwrapping, not handling optionals properly, and forgetting to use 'self' in closures.
Can you explain why force unwrapping is a bad practice?
Force unwrapping can lead to runtime crashes if the optional is nil. It's safer to use optional binding or nil coalescing.
What is optional binding?
Optional binding is a way to safely unwrap optionals using 'if let' or 'guard let', allowing you to handle nil values gracefully.
Are there any tools to help identify these mistakes?
Yes, tools like SwiftLint can help identify common coding mistakes and enforce style guidelines in your Swift code.
