1. Download XCode. XCode is the main setup you are going to be working with in order to develop the Apple Watch apps. (Please note that if you are a Windows user, there is a way to still develop Apple Watch apps, but things will be much easier if you use a Mac.) Swift is the language that you are going to use in order to develop your app.
2. Add interface elements. The first thing you want to do is add interface elements to your app. Perhaps you want to add a Button, or a Table. You have to make sure that you attach the various interface element appropriately, and within the correct body of the code–usually right after the introductory code. You want the interface elements to appear first thing after the introductory code so that you can call out your interface elements at the top of the computer code.
3. Try Swift Playgrounds. Before you actually put Swift into XCode, you may want to play around a little bit in Swift Playgrounds. Playgrounds are essentially where you can run your Swift code and see if you get the appropriate output.
4. Learn about variables. You want to call out your variables towards the top of your body of code, probably right below where you had put the code to declare your interface elements.
5. Learn about arrays, sets, and dictionaries. It will be very useful to you to learn what an array is, as well as a set and a dictionary. “Arrays are ordered collections of values. Sets are unordered collections of distinct values. Dictionaries are unordered collections of key-value associations” (“Collection Types,” 2015, pgh. 1).
6. Learn “If” statements. You want to make sure that you learn “If” statements, which are the preface to a condition. For example, you might want to say, “if variable x equals zero, then y equals x + 2.” Make sure you place brackets in the appropriate places for “if…then” statements. Write your statements in typical coding format.
7. Learn about “For” loops and “While” loops. “For” loops and “While” loops are also phrases used in coding that express conditions; you will want to study these intensively before using them.
8. Learn about functions. Learn about various types of functions, which will also definitely be key linchpins of your app. “Every function has a function name, [describing] the task that the function performs. To use a function, you ‘call’ that function with its name and pass it input values (known as arguments) that match the types of the function’s parameters” (“Defining and Calling Functions,” 2015, pgh. 2).
9. Add images and animations. Add images to your Apple Watch app by putting them in your Images cache in XCode. For animations, you are going to need to make sure that, instead of a single image, you need each portion of the animation divided into multiple images. Ensure they are in the proper format.
10. Create a sample app! Try to do a demo app first for your first Apple Watch mobile app.
These ten steps will help you build your first mobile app for the Apple Watch!
