Internationalization and localization of Apps in Xcode 6 and Swift
Internationalisation and Localization of apps is essential when you want the apps to seamlessly support different languages and region. Internationalization refers to process of providing a framework to the app for supporting multiple languages. And Localization refers to the process of making your app to support a particular locale such as German In this tutorial,…

Choose the template as Single View Application and click Next button. Enter name of the Product, Language as Swift then click…
Insertion Sort
Insertion Sort algorithm does the following Keeps the sorted numbers from left to right. Compares the left with right and interchanges the number if left is greater than right. Here is code snippet of Insertion Sort in Swift. [code language=”swift”]var inputArr:[Int] = [Int]() // generate random numbers for rIndex in 0..<10 { inputArr.append(((Int(arc4random()) % 100)))…
Reverse a String in Swift
Here is a simple code snippet written in Swift programming language for reversing a string. import Cocoa //Assigning a value to a String variable var str = “Hello, playground” //Create empty character Array. var strArray:Character[] = Character[]() //Loop through each character in the String for character in str { //Insert the character in the Array…

Make sure to select Playground under OS X if you want to use Cocoa framework and go for UIKit incase of iOS Another alternate way is to change the template using the Playground Settings.…
Binary search
After a simple bubble sort algorithm (not the most efficient sorting algorithm), let us try to implement Binary search in Swift Programming Language. Binary search algorithm can be applied only on sorted arrays. So let us first generate random numbers and store them in an array. Then call the bubble sort function to sort the…
Bubble Sort
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…
