Trailing Closures in Swift

TrailingClosures.swift

// Adapted from https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/Closures.html

// Here's a function that takes a closure as an argument:
func funFunction(closure: () -> Void) {
  // Do stuff and call closure when done
}
 
// Here's how you call this function passing the closure normally:
funFunction(closure: {
    // Closure code goes in here
})
 
// Here's how you call this function with a trailing closure:
funFunction() {
    // Closure is declared OUTSIDE the function's argument list! 
}
