Objective-C

The iOS codebase that predates Swift

Objective-C was the official language of iOS and macOS for decades, and a large share of the apps running on the App Store today were born in it. It is a mature language with direct access to Apple's APIs, and well-written Objective-C keeps working. The problem is rarely the language itself: older apps accumulate outdated dependencies, abandoned patterns and knowledge that left with the original team.

Let us be direct: we do not recommend Objective-C for a new app. Swift exists for that. Where we come in is the app that already exists: we take over legacy codebases, fix bugs, keep the app compatible with current iOS releases and keep the product published and healthy. Before touching anything, we run a code assessment to separate what is worth keeping from what needs a rewrite.

Because Objective-C and Swift coexist in the same project, migration does not have to be a big bang. We migrate module by module, starting with the code that changes most often, while the app stays live and keeps shipping updates. For whoever hires us, that means not throwing away the investment already made: the product keeps evolving while the codebase modernizes at a pace the business can absorb.
