FAQs
Objective-C is the original programming language that was used to create all applications for Apple’s iOS (iPhone/iPad) and Mac platforms for decades. It is an object-oriented language based on C.
Yes, many businesses continue to maintain and update their existing Objective-C apps, which remain essential to their operations.
Legacy App Development refers to the maintenance, support, and modernization of older software. In this context, it means working with an existing Objective-C app to fix bugs, ensure it works on new iOS versions, or migrate it to Swift.
This is the process of rewriting an app from Objective-C to Swift. The Objective-C development Companies often do this incrementally, running both languages in the same app (interoperability) to slowly replace old code with new, safer, and faster Swift code, minimizing risk.
If a legacy app is not maintained, it will eventually stop working. New iOS updates or new iPhone hardware can break the app, and unpatched security vulnerabilities can put your business and user data at risk.
iOS Objective-C Developers are senior software engineers who have experience with Apple’s original programming language. This is a specialized, legacy skill in 2025, as most new developers are only trained in Swift.
Security flaws, poor performance, and eventual incompatibility with newer iOS versions, all of which can lead to app failure or costly rebuilds.
