iOS Operating System As A Basis
iOS is an operating system created by Apple and released in June 2007. At that time, the company called it iPhone OS because it aimed to serve iPhones and iPods exclusively. Then, in 2010, Apple unified its mobile operating systems under iOS.
However, in 2019, a separate OS for iPads appeared, named iPadOS. Despite the different titles, developers only need to program an iOS app once for the Apple operating system. The app then can work well on iPhones and iPads.
Apple wants to upgrade its products continuously to adapt to varying customer demands. The latest versions of those operating systems are iPadOS 17.6.1 and iOS 17.6.1.
iOS App Development
Unlike Android operating systems, iOS is exclusive to Apple devices and cannot be used by other manufacturers. Developers can indeed program iOS apps for iPhones, iPads, and Apple Watches using the programming languages Swift and Objective-C. These apps can then be distributed to users through the App Store.
– Swift: A modern, powerful, and intuitive programming language designed specifically for Apple platforms. It’s known for its safety, performance, and ease of use.
– Objective-C: A more traditional language that has been used for iOS programming for many years. While Swift has become more popular, Objective-C is still a viable option for iOS app programming.
Furthermore, developing iOS apps requires Xcode, a software development kit (SDK) available for free but exclusively on Apple computers. This limitation may increase the development cost. That’s why businesses in Switzerland choose to partner with an app development agency. Yet, STS Software GmbH offers cost-effective solutions to program apps for iPhone. Choose us, and your iOS app development project will thrive!
Native iOS App Development
Native iOS apps can access many functionalities through APIs. For example, when you program an app for Apple Watch, it comes with features like powerful GPS and a microphone.
However, these native apps cannot run on Android devices due to the fact that they are on different software platforms.
Developers have to program apps for Apple iPad and apps for Android devices differently. If you work with iOS, you can take full advantage of the Apple ecosystem. But, this approach requires dedicated resources and expertise.
