Checking the number of items in a dictionary

In addition to keys and values, we have other useful properties. We can see the number of items in a dictionary using the count property. Let's try that by adding the following:

print("There are \(dictPizzas.count) total pizzas.")

Now, your code and output should look like this:

Along with a count, we can check whether a dictionary is empty. Let's use this in an if...else statement by adding the following:

if dictPizzas.isEmpty { 
  print("there are no pizzas") 
} 
else { 
  print("There are \(dictPizzas.count) total pizzas.") 
}

Now, your code and output should look like this:

This kind of logic is helpful when you want to display something back to the user or hide a UI.
