iOS development has changed significantly in the past decade. New features and technologies have been introduced, and the way that apps are developed and distributed has evolved.

• Programming Languages: Objective-C was the primary programming language for iOS development for many years. However, in 2014, Apple introduced Swift, a new programming language that is designed to be more modern, efficient, and easier to learn. Swift has quickly become the preferred programming language for iOS development.
• Development Tools and Frameworks: Apple has released a number of new development tools and frameworks over the past decade like Xcode, SwiftUI, and UIKit. These tools and frameworks make it easier for developers to build high-quality iOS apps.
• Device Types: For mobile devices, it started with the iPhone and iPod, but Apple has released a number of new device types and features over the course of time like the iPad, Apple Watch, and AirPods. New hardware brings in new challenges and capabilities.
• App Store Guidelines: Apple has also updated its app store guidelines on a regular basis. These guidelines ensure that apps are of high quality and meet Apple’s standards. Developers need to be familiar with the latest App Store guidelines in order to get their apps approved for the App Store.

Apple is expected to continue to focus on improving the performance and battery life of iOS devices. This will make iOS even more attractive to users and developers alike. Emerging technologies such as AI, ML, and AR are expected to be more widely adopted in iOS development in the coming years.

Security is a top priority for Apple. With new restrictions coming in from the EU, it will be interesting to see how Apple tackles the openness of app installation from outside their App Store while maintaining its image of being secure.

Overall, the future of iOS development looks bright. With its large and growing user base, iOS is a great platform for developers to build and distribute their apps and might be even more lucrative in the future.
