The best way to practice a new language is to write more programs using that language. Here is a Bubble Sort program written in Swift Programming language.

Data to be sorted = {12, 56, 32, 23, 67, 87, 45, 23,10, 11}

Bubble Sort

Bubble Sort is performed by comparing two number starting from the left and swapping the greater number to the right. And then moves one position to right until end.

Bubble Sort in Swift

This has a function named swapNumbers for swapping the values of array for the given two indexes. Then the for loop that compares the two numbers starting from left to right and uses swapNumbers function to swap the values if the left is greater than right.

var inputArr = [12,56,32,23,67,87,45,23,10,11]

func swapNumbers(index1 :Int,index2: Int) {

let temp = inputArr[index1]

inputArr[index1] = inputArr[index2]

inputArr[index2] = temp

}

for var index: Int = inputArr.count–1; index > 1; –index {

for var jIndex: Int = 0; jIndex < index; ++jIndex {

if inputArr[jIndex] > inputArr[jIndex + 1] {

swapNumbers(jIndex, jIndex+1)

}

inputArr

Here is the Swift code tested in Playground, you can see the sorted results in the sidebar

I came across this unique Swift job advert in stackoverflow.com posted by Criteo. (Need to add override for the init function, missed in the original job post)

var hello = "Hello, I am a Swift Program, paste me in the playground"

var doyouswift = "You think you have what it takes to build the next mobile advertising technologies ?"

class Hire {

var r = "&"

var d = "r"

var ec = "@rt"

func email() -> String{

return "look at gogogo's"

}

class HireMe: Hire{

var me = "[email protected]"

var crit = "e"

let o = ".com"

override init() {

super.init()

ec = "ruit"

}

override func email() -> String{

return super.email()+" preview, remove quotes and braces to reveal the email."

}

var gogogo = HireMe()

println(gogogo.email())
