As developers, we sometimes have to check and see if an array, set, string, or other collection types are nil.

In the past, you might write code like this:

let name = “”
if name.count = 0
{
print(“You did not give a name”)
}

But, with the new isEmpty statement, one can write the above like this:

let name = “”
if name.isEmpty
{
print(“You did not give a name)
}

Using the above statement makes development faster and easier to read and understand.
