Just like learning something new, learning to develop an iOS app is quite complicated yet fun, exciting, and rewarding. As a mobile development enthusiast, you should begin by learning how to code. Fortunately, if you aren’t versed in coding, you can leverage plenty of coding resources available online. Those with some coding knowledge will find the process easy, as they only need to check out Apple’s app development guidelines and tools.
Unlike other smartphone manufacturers, Apple highly restricts their applications for various reasons. As such, getting to know the guidelines can help you define your scope before developing an app. While the guide below won’t outline the step-by-step process of iOS app development, it provides essential pointers to help you develop the app.
Work on Xcode and Coding Language
Xcode is Apple’s integrated development environment for iOS and Mac applications. Therefore, this means that you should already have an Apple device, either a Mac or an iPhone. While there are workaround options, such as Hackintosh and Mac in Cloud, any serious iOS developer should consider investing in a serious working tool. With a Mac or iPhone, you can then download Xcode from Apple’s site.
Xcode is the main graphical interface that comes in handy in writing the app codes. It also comes with every other element essential for coding with iOS, including the recently inaugurated Apple’s Swift Programming language. Even as Apple is currently pressing for the use of Swift language, you can program iOS apps in other coding languages, such as Objective-C, which is based on the C-language.
Regardless of the coding language, you decide to use, the following tutorials and courses offer the best place to begin.
- Start Developing iOS Apps Today – anyone looking to lay a solid foundation of iOS app development should read this Apple’s official guide. The guide outlines tips for setting up and using Xcode, structuring iOS apps, app development guidelines, and uploading your app to Apple Store.
- Introducing Swift – beginner programmers should select Swift as their coding language of focus since it is Apples’ programming language of choice. However, it is easier to use and works just like Objective-C.
- Ray’s Objective-C Tutorial – old school app developers should check out this tutorial to learn the basics of Objective-C language. It also suits those who want to specialize in making iOS games.
- iOS App Development Classes – Code School’s and Stanford’s iOS development classes are the best courses to learn iOS app development basics.
You can learn this and more by enrolling in a coding Bootcamp or online coding courses. While these programs can be expensive, you can apply for financial aid from various sources, including scholarships from institutions. Veterans who are interested in pursuing app development benefit from G.I. Bill benefits. Without a doubt, you only need to learn the basics as other things come with experience. However, you should get a good grasp of the key variables, classes, pointers, loops, and data types that guide app development.
Review Apple App Store Guidelines
As mentioned, Apple place stringent restrictions on its apps. They have a specific view of apps to be uploaded into their store. As such, you should understand the specific rules provided in their guidelines before making the app. Otherwise, you will end up creating an app that won’t be allowed into Apple’s App Store.
Once you are done designing, Apple will review the application based on design, content, and technical specifics before uploading it into Apple Store. Therefore, check out the Review Guidelines page to find out the common reason why even the best apps get rejected. Some of the common reasons for rejection include;
- Crashes and bugs – before submitting your app, conduct a thorough test to ensure that it runs on the latest Apple software and has no bugs.
- Placeholder content – applications still in the development phase with placeholder content cannot be approved as well. Therefore, ensure that you finalize the texts and images before submitting the app for review.
- Similarly, the majority of Apple’s Application Programming Interface has specifically set guidelines. Therefore, if you plan to integrate your iOS app with Apple Pay or Healthkit, it is prudent that you familiarize yourself with these guidelines as well.
- Requesting permission – if your app requests permission to access user data, you should describe how the app will use personal information to avoid privacy issues.
- Incomplete information – provide all the details required to review your application when submitting. If a sign-in option is present, provide a functional demo account with username and password.
Apple also blocks applications that include skewed political and adult content.
Seek External Input
Seeking advice and recommendation from industry experts is part of the mobile app development protocol. While it is possible to create the app and submit it in a bubble, it is prudent to allow other people to evaluate your code. You should also invite testers to try your application before uploading into Apple Store.
That said, the best place to find experts in coding and mobile app development is TestFlight and GitHub. GitHub is an excellent platform for collaborative work and software versioning. The best thing is that GitHub integrates with Xcode easily, making it easy to save everything you do and allow access to coding experts for evaluation. You can as well use TestFlight to invite users to test the app before launching.
Though it may seem challenging, developing an iOS app revolves around mastering Xcode usability, coding, and going by Apple’s app development guidelines. Once you have understood the process, you can begin by creating simple apps, such as weather, currency converter, and calculator apps, using step-by-step tutorials available online. If you feel comfortable with Xcode and your programming language of choice from the tutorials, you can start working on your custom app.
