Shouldnt all strings have a value or something the says it could be empty or it might have a value. But making it empty isnt that wrong?

Question

Value of strings

Answer 1

No, that isn't wrong.
But you can also assign null to a string variable.

Answer 2

You have to remember the 'truthy/falsey' nature of languages.

In Swift, I believe it's like Ruby in that only nil and false are falsey. Every other type is inherently truthy.
