What Exactly Is iOS App Development?
The process of creating mobile applications for Apple hardware, such as the iPhone, iPad, and iPod Touch, is known as iOS application development. Swift or Objective-C is used to create the software, which is then published to the App Store for people to download.
You might be wary about developing iOS apps if you work as a mobile app developer. For instance, every developer needs a Mac computer, which is generally more expensive than Windows-based computers. Your software must also pass a rigorous quality assessment procedure after it is finished development before being made available through the App Store.
However, you have obvious reasons to get involved in iOS app development if any of your company’s staff, clients, or partners are among the hundreds of millions of Apple iPhone and iPad users worldwide. And despite potentially high entry barriers, creating an iOS app can be just as simple—and in some situations, even simpler—than creating one for Android. You may become an iOS app developer with the correct preparation and tools.
In order to create an iOS app, you must have the following before writing a single line of code:
- A Mac computer running the most recent macOS release.
- The integrated development environment (IDE) for macOS is called Xcode, and it can be downloaded for free from the Mac App Store.
- An active Apple Developer account costs USD 99 per year. ( For uploading the app on the app store)
Together, these three conditions: An app can only be published to the Apple App Store by active members of the Apple Developer Program. The App Store only accepts applications signed and published by Xcode. Only macOS and Apple PCs are compatible with Xcode.
The good news is that Xcode provides a lot more features than simply the ability to sign and publish your finished software. Virtually everything you need to develop iOS apps is included in the IDE, including a user interface designer, code editor, testing engine, asset catalogue, and more.
Choose a programming language for iOS.
Currently, there are just two programming languages available for creating iOS apps.
- Objective-C: Early 1980s programming language Objective-C served as the main platform for all Apple products for many years. The object-oriented programming language Objective-C, which is derived from the C language, is focused on conveying messages to various processes (as opposed to invoking a process in traditional C programming). Instead of converting their older Objective-C applications to the 2014-introduced Swift framework, many developers want to preserve them.
- Swift: The new “official” language of iOS is the Swift programming language. Although Swift and Objective-C are quite similar, Swift is intended to have a simpler syntax and is more security-focused than its predecessor. Because it and Objective-C share a run time, updating apps with legacy code is simple. Even for those who are just learning to programme, Swift is simple to learn. Unless you have a compelling reason to continue with Objective-C, you should aim to utilise Swift to develop your iOS app since it is faster, more secure, and simpler to use than Objective-C.
Make use of libraries and APIs
One of the major advantages of iOS app development is the extensive collection of developer resources available to you. Because of the standardization, functionality and consistency of iOS app development, Apple is able to release native APIs and libraries as kits that are stable, feature-rich and easy to use. You can use these iOS SDKs to seamlessly integrate your app into Apple’s existing infrastructure.
To standardise the connection between the toaster and the phone, for instance, if you’re developing an app controller for a smart toaster oven, you can utilise HomeKit. Between their smart toaster oven and their smart coffee machine, users will be able to coordinate communication. In addition to Siri, Apple’s virtual assistant, there are kits for creating games (such as SpriteKit, GameplayKit, and ReplayKit), health applications, maps, and cameras.
These comprehensive kits enable you to easily utilise iOS capabilities and incorporate third-party applications, allowing you to develop apps that link to a social network, use the camera or native calendar app, or automatically capture replay footage of particularly exciting gaming moments.
Spread out towards the cloud
iPhones are capable gadgets. However, if a task requires a lot of resources, think about outsourcing it to the cloud. Your app can use the cloud for storage, database management, and even app caching by connecting to cloud-based services via APIs. Additionally, you can add cutting-edge next-generation features to your app.
Regional and international testing
Even the most skilled programmers occasionally fail to write perfect code the first time. When you’re done developing your iOS app, you must test it. Fortunately, you won’t need to test mobile devices from several manufacturers, unlike when developing for Android. iOS is Apple’s unique mobile operating system, available only on Apple iPhones. There are still fewer devices to test with iOS than there are with Android, even though you might want to test your iOS app on several iPhone models (with different operating systems).
You should start testing in Xcode itself. Xcode offers automated UI testing in addition to the usual unit tests you’re familiar to. To find any problems, you can create tests that move about your UI and use your app as a user would. The UI testing mimics how a real user would interact with your app rather than using APIs to communicate with your code. You may automatically obtain UI testing that is frequently more thorough than what any human can do as long as you build tests that cover every component of your programme.
You should still allow people to beta-test your product, even if your tests cover every interaction a user might have with your programme. Apple makes it simple for friends, family, or your customer base to evaluate your app using its TestFlight tool, even though you can sideload programmes to iOS devices without submitting them to the App Store. Members of the Apple Developer Program are able to conduct internal testing using TestFlight with up to 25 team members and 30 devices each. In order to release your new iOS app to outside testers, you can give your iOS app development team the opportunity to try it out in a small group and be ready for the Apple Beta review.
Even if your tests cover every interaction a user might have with your programme, you should nevertheless let people beta-test it. Although you can sideload apps to iOS devices without submitting them to the App Store, Apple makes it simple for friends, relatives, or your client base to assess your app using its TestFlight service. Internal testing can be carried out by members of the Apple Developer Program utilising TestFlight with up to 25 team members and 30 devices each. You can allow your iOS app development team the chance to test it out in a small group and be prepared for the Apple Beta review before releasing your new iOS app to outside testers.
Upload your application to the App Store.
You must publish your iOS software to the App Store once you’ve finished developing and testing it. Through Xcode, you may submit and sign your app. Keep calm: The app review process can take a while, and you may need to go through several rounds of rejection, revision, resubmission, and rejection before receiving your ultimate clearance.
Once everything has been approved, you may use a tool called App Store Connect to generate your App Store page and publish your app to the App Store. Remember that Apple gets a 30% share of your sales in addition to the $99 yearly price they ask to join the Developer Program if you intend to sell your app.
