Swift Grammar Note 01

There are so many new and exciting places in Swift. Damn it

var Display:int {

Get ()

Set ()

}

Tuple:

Let x: (D:double, e:string, f:int) = (3.1415, "Hello", 1)

X.D X.E X.F

Let (a,b,c) = X

Print (A,B,C)

Range:

Let array=["a", "B", "C", "D", "E"]

Let SubArray1 = array[2...4]//C d E

Let SubArray2 = array[2..<4]//C D

than the Python string [::] or to be nearly

For LOP in 1...100//printing from 1 to 100

The class in Swift is referenced (as in Java), functions, etc. can change the values of the members passed into the class

class Foo {    var value:int = 100}func Add (f:foo) {    F.value + = 1}let test = foo () Add (test) Test.value

Array:

var a = array<string> ()

Or

var a = [String] ()

Filter map reduce

Dictionary

var dic = dictionary<string, int> ()

var dic = [String:int] ()
