Objective C is a programming language used primarily for developing apps on Apple's platforms, including iOS and macOS. It is an object-oriented language that adds Smalltalk-style messaging to the C programming language. Despite the rise of Swift, Objective C remains crucial for maintaining existing applications and integrating with legacy code.

An Objective-C developer is a software engineer who builds, maintains, and debugs native applications for Apple platforms using the Objective-C programming language. Objective-C remains a foundational language for iOS, macOS, watchOS, and tvOS applications, particularly for legacy codebases, framework-level work, and projects that interoperate with C and C++ libraries. Hiring a skilled Objective-C programmer ensures your existing Apple software stays stable, secure, and compatible as the iOS and macOS ecosystems continue to evolve.
Objective-C engineers produce native iOS and macOS applications, SDKs, and reusable frameworks that integrate cleanly with Apple's Cocoa and Cocoa Touch APIs. Many production apps still ship with substantial Objective-C code, especially in finance, media, healthcare, and enterprise tooling, where rewriting an entire codebase in Swift is neither practical nor cost-effective.
A capable Objective-C developer can extend legacy applications, bridge Objective-C with Swift through mixed-language modules, optimize memory and performance, and prepare older projects for App Store submission under the latest iOS and Xcode requirements. The commercial value is straightforward: keep your shipped product working, supportable, and compliant without losing the engineering investment already in your codebase.
Most Objective-C engagements fall into a predictable set of deliverables. Scope your brief around the ones that match your project.
Strong Objective-C developers work fluently across Apple's standard toolchain and the libraries that surround it. Look for hands-on experience with Xcode, LLDB, Clang, and Apple's developer documentation workflow. Common frameworks include UIKit, AppKit, Foundation, Core Data, Core Animation, AVFoundation, Core Location, MapKit, and SceneKit. Dependency management is typically handled through CocoaPods or Carthage, and version control through Git.
Engineers comfortable with both Objective-C and Swift are especially valuable for migration projects, since mixed-language interoperability requires a precise understanding of nullability annotations, generics bridging, and module exports. Familiarity with continuous integration tools such as Fastlane, Bitrise, and GitHub Actions is a strong signal for production-ready candidates.
Objective-C work spans any sector with established iOS or macOS software. Common engagements include banking and fintech apps with long compliance histories, media and entertainment platforms with extensive AVFoundation pipelines, healthcare applications under strict regulatory review, enterprise mobility tools, point-of-sale systems, and SDK vendors who distribute libraries to third-party iOS developers. Game studios occasionally hire Objective-C engineers for SpriteKit or Metal projects, and accessibility-focused apps often rely on mature Objective-C codebases to support older devices.
Look for engineers with a clear track record of shipped iOS or macOS apps, ideally listed on the App Store, and a portfolio that includes both new development and legacy maintenance work. Strong candidates can articulate the differences between manual retain/release and ARC, explain how Objective-C runtime features like method swizzling and categories work, and discuss when those features should and should not be used.
Profile signals worth weighing include completed iOS or macOS projects, repeat-client history, ratings, and demonstrated experience with the specific frameworks your project uses. Ask candidates to walk you through a real bug they fixed in production code.
Sample interview questions you can copy and use:
Freelancer.com gives you access to a global pool of iOS and macOS engineers, including specialists who have maintained Objective-C codebases for a decade or more. You can post a project on Freelancer.com and receive competitive bids from developers across multiple time zones, compare portfolios, read verified client reviews, and shortlist candidates whose experience matches your stack. Clients set their own budgets, and Milestone Payments protect funds until agreed deliverables are met. Whether you need a short bug fix, a Swift migration, or full ownership of a legacy app, freelancers on Freelancer.com cover the full range of Objective-C engagements.
Ready to extend, maintain, or migrate your iOS or macOS application?
Hiring an Objective-C engineer works best when you frame the project around your existing codebase and the platforms you ship to. The steps below walk you through writing a brief that attracts the right bids, evaluating proposals, and awarding the work with confidence.
The brief is the single biggest factor in the quality of bids you receive. Clear technical context filters for developers who genuinely match your stack and weeds out generic responses. Head to the
Bids on Objective-C projects are short proposals, not just price quotes. Strong candidates respond to the technical specifics of your brief, raise sensible clarifying questions, and propose a realistic approach. Read each proposal carefully and use Freelancer.com's chat to probe further before shortlisting.
The final decision should weigh proposal quality against profile evidence. For Objective-C work, consistency across multiple shipped apps matters more than a single impressive sample. Review portfolios for both legacy maintenance and new development experience.
Most new iOS and macOS projects start in Swift, but Objective-C remains essential for maintaining existing apps, working with older SDKs, and writing code that interoperates closely with C or C++. If you have a shipped product with Objective-C in it, hiring an Objective-C developer is usually more economical than a full rewrite.
Yes, and most experienced iOS engineers are comfortable in both languages. This is particularly important for migration projects, where the developer needs to maintain Objective-C modules while gradually introducing Swift through bridging headers and mixed-language targets.
Timelines depend heavily on scope. A targeted bug fix or small feature can take a few days, while a full app migration from Objective-C to Swift can run several months. Sharing your existing codebase size and Xcode version with bidders helps them give realistic estimates.
If your codebase is predominantly or partly Objective-C, hire someone who lists Objective-C as a core skill rather than a general iOS developer who works only in Swift. The runtime, memory model, and syntax differences are significant enough that Objective-C-specific experience meaningfully reduces project risk.
For maintenance, migrations, bug fixes, and most single-app projects, an experienced freelance Objective-C developer is faster and more cost-effective than an agency. Agencies make more sense when you need a multi-disciplinary team covering design, backend, QA, and project management simultaneously.
