Swift Alternatives for Cpp-style for-in loop

var str = "Hello, playground"

//Converting a string into an array
var arr = Array(str.characters)
I wrote all of this code in playgrounds. I have also used their example.

//Looping n times
(0..<10).forEach({num in print(num)})

//old version
for var i = 0, i < 10; i += 1{
	print(i)
}
/*
It prints from 0 to 10 exclusively to the console
*/

//Looping n time reverse
(0..<10).reverse().forEach({number in print(number)})

(0..<10).reverse().forEach({print($0)})

//old version
for var i = 10, i > 0; i -= 1{
	print(i)
}
/*
It prints from 10 to 0 exclusively to the console
*/
//Looping with stride
(0.stride(to: 10, by: 2)).forEach({print($0, terminator: " ")})
/*
0 2 4 6 8
*/
//Looping through array values
//I want to print them in one line
arr.forEach({char in print(char, terminator: " ")})
/*
H e l l o ,   p l a y g r o u n d
*/
//Reverse looping through array values
arr.reverse().forEach({char in print(char, terminator: " ")})
/*
d n u o r g y a l p   , o l l e H
*/
//Looping through an array with index
arr.enumerate().forEach({(index,char) in print("\(index):\(char)", terminator: ";")})
/*
0:H;1:e;2:l;3:l;4:o;5:,;6: ;7:p;8:l;9:a;10:y;11:g;12:r;13:o;14:u;15:n;16:d;
*/
//Looping through array indices
arr.indices.forEach({index in print("i:\(index)", terminator: " | ")})
/*
i:0 | i:1 | i:2 | i:3 | i:4 | i:5 | i:6 | i:7 | i:8 | i:9 | i:10 | i:11 | i:12 | i:13 | i:14 | i:15 | i:16 |
*/
var airports = ["YYZ": "Toronto Pearson", "DUB": "Dublin"]

//Looping through a dictonary
airports.forEach({(key,value) in print("\(key): \(value)")})
/*
DUB: Dublin
YYZ: Toronto Pearson
*/

//Looping through key in a dict
airports.keys.forEach({(key) in print("\(key)")})
/*
DUB
YYZ
*/
//Looping through values in a dict
airports.values.forEach({(value) in print("\(value)")})
/*
Dublin
Toronto Pearson
*/
