Apple
Programming for Apple phones requires developers to use Apple's proprietary programming language, Swift.Swift is designed to be fast, efficient, and easy to use, with a syntax that is similar to other popular programming languages such as Python and JavaScript. In addition to Swift, developers also use Xcode, Apple's Integrated Development Environment (IDE), which provides a range of tools and features for building, testing, and debugging iOS applications.
Android
Android development refers to the process of creating mobile applications that run on Android devices, such as smartphones and tablets. Developers use the Java programming language to write code that runs on the Android operating system, which is based on the Linux kernel. Android development requires the use of Android Studio.We also use the C# framework Xamarin.Forms that requires the use of Visual Studio.This can also be used for multi platform mobile apps.
Multi Platform
Multi-platform mobile app development refers to the process of creating mobile applications that can run on multiple operating systems, such as iOS, Android, and Windows, using a single codebase. Xamarin.Forms is a popular framework for multi-platform mobile app development that uses C# and XAML to create native user interfaces that run on multiple platforms. Xamarin.Forms allows for support of platform-specific features such as push notifications.
