Understanding difference between arguments and parameters in Swift.
This was the first confusing thing I noticed in Swift when I transitioned from Java.
Usually we have something like this, here we are using argument and parameter interchangeably.
But then I saw this, I thought what’s this???
two parameters or one?
After some confusions and research I found that this is what Swift calls as “Argument label”. In Swift the argument and parameter can be used separately in a way that the argument is responsible for the readability of the method call and parameter is used for the method body execution.
There are few variations of argument and parameter usage in Swift.
Same argument and parameter labels.
Used as createUser(name: “Jatin”)
Different argument and parameter labels.
Used as createUser(with: “Jatin”)
No argument label
Used as createUser(“Jatin”)
Do share it if you found it useful and please clap if you can!!!
