How to Create Your Own iOS App

Apple is clearly a leading company in creating both mobile devices and the apps that those
devices use. Its large market share means that most companies or clients will want their
app feature in Apple’s App Store, and developers need to learn to build apps for Apple
devices.

Tools You Will Need

To build apps for Apple, you need a Macintosh computer. The primary programs used to
build Apple apps only run on the OS X operating system, which is the primary operating
system for Macs. There are some third-party tools that allow development on PCs, but those
are not endorsed by Apple.
To develop an app, download the current version of Xcode onto your Mac. It’s available in
the Apple App Store for free. You’ll need to make sure your Mac’s operating system is
compatible with the current version of Xcode. Xcode allows you to create a user interface by
dragging and dropping elements onto the screen, and it allows you to create the rules and
logic that power your app by writing code. Xcode also allows you to test your app to make
sure it works the way you want it to.
Apple uses two primary programming languages: Objective-C and Swift . Swift is the latest
version, and its syntax is more like plain English and is easier to use.
To place an app in the App Store, you’ll need an Apple Developer membership. Memberships
require an annual fee (currently $99), and allow you to publish as many apps as you want
into the App Store and lets others download and install your app. Your membership gives
you access to Apple’s Provisioning Portal , where you will upload your certificates and create
profiles that control on what devices your app can be installed, and iTunes Connect , where
you will create the catalog listing for your app, upload and publish your app. iTunes Connect
will also allow you to check the statistics of your app, such as downloads, earnings, in-app
purchases, and more.

Creating Your App

Before you start, you need to know where you want to go. Start by clearly outlining the
purpose of your app. Understand what problem you’re trying to solve or what service you
want to provide. Think about your user interface: what content will your app present, and
how will users interact with it? It can be helpful to sketch out your app by creating a
storyboard that shows how your app will work. Xcode includes a powerful Storyboard
feature that allows you to create a prototype where you set up screens with images and
objects. The screens can be connected by segues which include transition effects and
navigation.
To familiarize yourself with Xcode, you can start by building a very simple app. This app will
display a message on the screen of an iPhone. Follow these steps:
● Start Xcode and select “Create a New Xcode Project” from the splash screen.

Xcode

● Make sure you’re in the Application section under iOS and choose “Single View
Application” and click “Next.”

iOS Template

● In the next screen, you’ll need to provide several pieces of information.
● Enter a product name for your app. In this example, we’ll use a phrase commonly
used by new programmers, and enter “Hello World.”

iOS Options

● Enter your organization name, or your own name, whichever is applicable.
● Enter an organization identifier, which is typically [your organization name].com
● For this example, choose Swift as the language.
● For this example, choose iPhone as your device.
● For this example, make sure “Use Core Data” is unchecked.
● Click “Next.”
● Make sure the “Create Cit Repository” box is unchecked, and save the file anywhere
you wish. Click “Create.”

iOS

● A new file will be created. In the panel on the left, you’ll see a file menu labeled
“Hello World.” Expand the screen to see your project configuration settings.
● Click Main.storyboard, and your screen will become a view for your application.
Remember, this is a single-screen application. The arrow on the screen indicates
your starting point. More complex apps have multiple screens and views, and the
arrow shows which one you’re currently working on.

iOS Main Story Board

● In the Library pane in the lower right-hand corner, you’ll find lists or grid views of
elements you can add to your screen. Enter “Label” in the search box, and when it
appears in the library, click it and drag it to the screen.
● Double-click the text of the label, and type in “Hello, World.”
● Click on the label, and then at the bottom of the screen, choose the Align icon. A
menu will appear, titled “Add New Alignment Constraints.”

iOS

● Choose “Horizontal Center in Container” and choose “Vertical Center in Container.”

This will center your label on the screen. Click “Add 2 Constraints.” Gridlines will
appear on the screen, showing where the label will be positioned.

iOS New Alignment Constraints
● Click the “Run” icon (a triangle pointing right) in the upper left-hand corner of your
screen.

iPhone Simulator

● A simulator of an iPhone screen will appear, with the phrase “Hello, World” in the
center of the screen on a white background.
