Hi! Today we will learn Swift.

Commands

Commands are simple. They look like this:
print(“Hello World!”)
As you can see, these commands don’t have a semicolon, unlike JavaScript and a few other languages.
Output:
Hello World!

Variables

It looks like this:
var name = 3
Output:
name = 3
Again, it doesn’t have a semicolon.
Variables can be changed, like this:
Add:
name += 1
Output:
name = 4
Subtract:
name -= 1
Output:
name = 2

Constants

These are written like this:
let name = 3
Output:
name = 3
You can not change these, so name will always be equal to 3.

Loops

Loops are written like this:

for i in 1...3{
   //This loop repeats 3 times.
}

This loop does nothing, but to make it do something, add code inside the curly brackets.

That’s it for today!
