2. Swift 4 – Environment
Swift 4
Try it Option Online
You really do not need to set up your own environment to start learning Swift 4
programming. Reason is very simple, we already have set up Swift 4 environment online,
so that you can execute all the available examples online at the same time when you are
doing your theory work. This gives you the confidence in what you are reading and in
addition to that, you can verify the result with different options. Feel free to modify any
example and execute it online.
Try the following example using the Try it option available at the top right corner of the
following sample code box:
import Cocoa
/* My first program in Swift 4 */
var myString = "Hello, World!"
print(myString)
For most of the examples given in this tutorial, you will find a Try it option, so just make
use of it and enjoy your learning.
Local Environment Setup
Swift 4 provides a Playground platform for learning purpose and we are going to setup the
same. You need xCode software to start your Swift 4 coding in Playground. Once you are
comfortable with the concepts of Swift 4, you can use xCode IDE for iSO/OS x application
development.
