What does an iOS developer do?
An iOS developer builds and maintains apps for iPhone and iPad using Swift and Apple's frameworks. They build screens, connect to APIs, handle the app lifecycle and fix bugs. At the entry level they deliver assigned features, test on real devices and learn Swift, UIKit or SwiftUI and the App Store submission process with support from senior developers.
Should I learn UIKit or SwiftUI for iOS?
Learn both over time. SwiftUI is Apple's newer, declarative way to build interfaces and is where the platform is heading, so it is important for new work. UIKit still runs most existing apps and is needed to maintain them. A fresher can start with SwiftUI but should understand UIKit too, since many Indian jobs still use it.
Do you need a Mac to be an iOS developer?
Yes. iOS development requires Xcode, which runs only on macOS, so you need a Mac to build and test apps and to submit to the App Store. Many companies provide Apple hardware for this. If you are learning, access to any Mac lets you practise Swift and build simple apps for your portfolio.
