iOS Developers create applications for Apple devices, such as the iPhone and iPad. Their work activities are similar to general Mobile App Developers, except iOS Develops focus strictly on developing apps for Apple’s iOS operating system. Some typical daily tasks for iOS Developers include developing the UI of apps using Xcode and Objective C programming language, testing app features and addressing bugs, crafting new features and patches based on user feedback, collaborating with other departments and conveying app features and updates to non-technical stakeholders.
