Arrays

Arrays
1. Declare:
var someInts = [Int]()
var someStrings = [String]()

OR

var someInts: [Int] = [6, 8]


2. Add a value:
someInts.append(4)
someStrings.append("ABC")
someInts += [6, 8]

3. Count the number of items in the array

print(someInts.count)
print(someStrings.count)

4. Get value out of array, based on index:

print(someInts[2])
//This prints the third value



Notes:
- Indexes start with 0
- "/\n" means to print a new line.

5. Splitting a string into an array using a separator:

fullNameArr = fullName.components(separatedBy: " ")

New Lines:
let text = "line1\nline2"
let array = text.components(separatedBy: CharacterSet.newlines)
