Are closures necessary in Swift?

Question

Closures

I am learning the language and the topic of closures was extremely difficult and disgusting for me. Syntax in understanding is difficult, although it would seem simple. Still, I would like to ask if you use closures, and is this topic really important?

Answer 1

umm.... closures are just a way to keep the space above and make the code clearer.
yes, you can do without them. but better with them.
what exactly is your problem?

Answer 2

In short, yes, to both questions.
