Work with Objective-C experts trusted by the world's top tech teams.

Usually, no. If your Objective-C app is stable and generating revenue, a 'big bang' rewrite is incredibly expensive and risky. Apple strongly supports Objective-C to this day. Instead, we recommend a 'Strangler Fig' approach: we maintain the existing Objective-C core, but write all new features and screens in modern Swift, bridging the two languages together.

Yes, the vast majority of newer iOS developers only know Swift. However, our rigorous vetting process ensures we retain senior Apple engineers who cut their teeth on Objective-C prior to 2014. These veterans deeply understand raw pointers, manual memory management, and the highly dynamic runtime that makes Objective-C unique.

Yes, but not directly, as SwiftUI is exclusively a Swift framework. However, because we can seamlessly bridge Swift and Objective-C, our engineers write the new UI components in SwiftUI, wrap them in a Swift `UIHostingController`, and then present that view controller natively from your existing Objective-C code.

As Apple updates iOS, they routinely deprecate older APIs (like UIWebView or NSURLConnection) and enforce much stricter privacy permissions (like location or photo access). Our maintenance engineers use Xcode Instruments to track down exactly where the modern OS is terminating the legacy app, updating those specific API calls while leaving the rest of your business logic intact.

Because Objective-C evaluates method calls (messages) at runtime rather than compile-time, we can dynamically intercept and change the implementation of a function while the app is running. This is called 'Method Swizzling'. While dangerous in the wrong hands, our experts use it safely to patch bugs in closed-source third-party SDKs or implement deep, global analytics tracking.

ARC (Automatic Reference Counting) was introduced by Apple to automatically insert memory `retain` and `release` calls at compile time. While it handles most memory management, it cannot prevent 'Retain Cycles' (where two objects hold strong references to each other, preventing them from being deleted). Our engineers are experts at hunting down these cycles to prevent memory leaks.

Objective-C is a strict superset of C, meaning you can write pure C code directly inside an `.m` file. For C++, we rename the file to `.mm` (Objective-C++). This allows us to instantiate raw C++ classes (like a custom physics engine or cryptography library) directly alongside high-level iOS UI code, achieving maximum performance with zero bridging overhead.

Abandoned third-party libraries are the biggest threat to a legacy app's lifespan. We audit your `Podfile`, identifying libraries that will soon break on modern iOS versions. We then systematically replace them with actively maintained forks, migrate them to Swift Package Manager (SPM), or rewrite the specific functionality natively.
