Even if you want to develop an iPhone application and use it for your business, or develop a game application, programming beginners may not be able to put it into practice. For such people, we will introduce the procedure for iPhone application development and its introductory part. The smartphone penetration rate in America is extremely high, and the iPhone occupies about half of the smartphone market share. The existence of apps is what characterizes the popularity of the iPhone, and many people want to develop iPhone apps and connect them to their business, but do not know exactly how to do that.
For those who are new to application development, we will introduce what is necessary for iPhone application development and what specific steps should be taken to create, publish, and then successfully run an iPhone App.
iPhone App Development Requirements
To develop an iPhone application, you need the following:
An Apple Mac is required to install the software "Xcode" described below. This is because Xcode can only be installed on a Mac, but it doesn't require a high-end Mac Pro, and any currently available model can be used. However, it is safer to make the memory and storage capacity as large as possible.
Also, keep this in mind as a small display size will also reduce the work area.
Xcode has become an indispensable software for iPhone application development, and you can do everything from application development to testing and uploading.
Its features range from a text editor for writing programs, an interface builder that allows you to create apps graphically, a debugger that tests your app for bugs, and an iOS simulator that simulates your iPhone device screen.
This Xcode can be downloaded for free from the App Store , but you'll need your Apple ID, so don't forget to register.
iPhone application development procedure
When your Apple Mac and Xcode are ready, install Xcode and start developing iPhone apps. The Xcode installation procedure is similar to a regular macOS application. Here is the step by step process for iPhone App development:
First, create a project that stores everything you need, including the source code and images that make up your app.
The template screen may be displayed by default, but if it is not displayed, click File> New> Project from the menu bar to display the template screen.
Select iOS> Application to create an iPhone app, select the simplest Single View Application and click Next.
Next, the screen for setting project options will appear, so set each one.
• For Product Name, enter the name of the app. You can change it.
• For Organization Name, enter the company name, but you can leave it blank.
• For Organization Identifier, you typically enter the com. Company name.
• Bundle Identifier automatically creates an ID that identifies the app.
• For Laguage, select the development language. Apple recommends Swift.
• For Device, select the device that the app supports.
When debugging, check Unit Test / UI Test and click Next.
The project save screen will appear, so specify the save location and click Create.
Source code editing
When the project creation is completed, the project screen will be displayed.
The project screen is roughly divided into three areas: a navigator area for selecting files to edit on the left side, an editor area for editing files in the center, and a utility area for setting parts on the right side. Select with the navigator. The contents displayed in the editor will change depending on the file you have created.
If you want to view Swift and edit the source code, click ViewController.swift in the navigator.
Similarly, if you find and click main storyboard in the navigator, you will see that the editor is now the iPhone screen. Create a visual for your app on this screen.
Specifically, there is a library palette at the bottom right of the utility, from which you can select various tools and drag and drop them into the editor.
For example, you can enter text by dragging and dropping "Label", or you can place an image by finding "Image View" and dragging and dropping.
In this example, the Image View is dragged and dropped to fill the screen.
Once your app development is complete, you can launch the iOS simulator from Xcode's tools and test the app's behavior. Click Xcode> Open Developer Tool> iOS Simulator from the menu bar to start the iOS simulator and display the iPhone screen.
The icon of the app under development is displayed here, so click it to check the operation of the app.
iPhone app release
In order to release a fully developed app, it is necessary to enroll in the paid iOS Developer Program, upload it, register the app and apply after the steps such as certificate creation.
Enroll in the iOS Developer Program
First, go to Apple's Developer site , register with your Apple ID, then purchase the iOS Developer Program and create an account. This account not only registers developer information, but also creates Production Cerfiticate as a product certificate of the app, creates an App ID that is an ID for each app, and links them with the UDID of the registered device ID, Provisioning. Used to create a Profile.
iPhone app upload
Once the required files are created, access iTunes Connect, register the app from My App, and "Archive" the app in Xcode. When the archive is completed, the apps will be listed, so perform "Validate" = verification, and if there are no problems, in the end, click the "Submit to App Store ..." button to complete the upload.
iPhone app registration and application
After uploading the app, add the app information to the app newly registered with iTunes Connect and apply. At this time, you need to register an app icon of 1024 x 1024 pixels, two or more screenshots of the app, and enter information such as app version information and overview, support URL, age limit specification, etc. ..
At this point everything is ready. The iPhone app usually takes a week or so to be reviewed by Apple, so wait until the release is complete.
Earning money from iPhone Apps
There are three ways to earn money after you have an iPhone App developed: pay for the app you want to release, show ads within the app, and set up in-app purchases.
The paid download option is when you sell the released app for a fee. It seems that game apps and some utility apps are often paid downloads, but unless it is a well-known app or an app version of a popular game, it might be hard to convince users to spend money on an App they have never used.
You can make money from ads by displaying them in the app. The app itself is a revenue model that assumes that users will use it for free, but it can be said to be the same idea as displaying advertisements on Youtube and earning profits, such as displaying advertisements on websites. If you're an individual and expect to make money from your app, this is a great way to do it.
In-app purchases are a popular revenue model for game apps. There are ways to do this, such as making additional items appear and sell in the game, or charging when proceeding to additional stages, but the app itself is premised on being free or low-priced.
In-app purchases also work for Apps like meditation Apps, self-improvement Apps, Dating Apps, and many other types of Apps.
Things to consider when publishing your iPhone App
After the iPhone App development process, it is important to consider various factors when releasing the App. You must consider all the above-mentioned procedures, how you want to approach them and who do you want to trust with implementing these procedures. You should have a clear understanding of what you want from your App.
Apart from the application publishing procedure that must be done carefully, the application development itself can be a time-consuming process as well with the need for trial and error in the local environment. We recommend that you experiment with various ideas and only then go ahead with iPhone App development so that you end up with an Application that will be liked by users and will be profitable as soon as possible.
