It's remarkable how similar Swift and Rust are w.r.t syntax.

Rust, Swift

let x = 42; let x = 42

let x: i32 = 42; let x: Int = 42

let _ = 42; let _ = 42

let pair: (char, i32) = ('a', 17); let pair: (String, Int) = ("a", 17)

let (some_char, some_int) = ('a', 17); let (some_char, some_int) = ("a", 17)

fn greet() { println!("Hi there!"); } func greet() { print("Hi there!") }

But, the languages are so different, for instance in Swift

let x x = 42

let y = 13 let y = y + 3

Wont fly for instance. I am trying to come up with the simplest explanation possible for this but I can't - goes to show how much I understand either of the languages.
