Objective-C is no longer the language Apple promotes, but it still runs a large share of the iOS and macOS software that businesses depend on. Banking apps, healthcare tools, retail apps and internal enterprise products built between 2008 and 2016 often contain hundreds of thousands of lines of Objective-C. Keeping that code stable, secure and compatible with each new iOS release takes specialists who know both the old language and the modern Swift ecosystem.
This guide reviews five Objective-C development companies worth shortlisting in 2026, compares them side by side, and explains the services, selection criteria and costs you should expect.
What Is an Objective-C Development Company?
An Objective-C development company is a software vendor that builds, maintains and modernizes Apple-platform applications written fully or partly in Objective-C. In 2026, most of these firms are iOS specialists who work in mixed Objective-C and Swift codebases rather than pure Objective-C shops.
Core Services Offered by Objective-C Development Companies
Typical engagements fall into four groups:
- Maintenance of legacy apps: bug fixes, crash reduction, and updates for new iOS, iPadOS and Xcode versions.
- Feature development in existing codebases: adding functionality without destabilizing older modules.
- Modernization: refactoring architecture, replacing deprecated APIs such as UIWebView, and improving test coverage.
- Migration to Swift: moving code to Swift module by module while keeping the app shippable at every step.
Why Businesses Still Need Objective-C Development
Rewriting a mature app from scratch is expensive and risky. Many companies choose to keep proven Objective-C business logic and modernize around it. Objective-C also remains relevant because:
- Apple still supports it in Xcode, and Swift interoperates with it through bridging headers and the Objective-C runtime.
- Many established SDKs, internal frameworks and C/C++ libraries are wrapped in Objective-C.
- Regulated industries prefer incremental change, because every rewrite triggers new security reviews and compliance testing.
- Swift-only developers often struggle with manual memory patterns, runtime features such as method swizzling, and older architecture styles found in legacy code.

Key Services to Look for in an Objective-C Development Partner
iOS App Development
A strong partner should write new features in Swift while respecting existing Objective-C patterns. Ask how they decide which language a new module uses and how they manage interoperability through bridging headers and nullability annotations.
Legacy iOS App Modernization
Modernization covers more than syntax. It includes replacing deprecated APIs, moving from manual retain-release code to ARC, upgrading dependency managers, introducing Swift Package Manager, and adding automated tests before risky changes.
Objective-C to Swift Migration
The safest approach is incremental. Good vendors start with a code audit, migrate leaf modules and models first, keep the app releasable after every sprint, and track crash rates throughout. A full big-bang rewrite should be the exception, not the default.
API Integration and Maintenance
Older apps often depend on outdated networking libraries or deprecated authentication flows. Your partner should be able to update API layers, adopt modern security standards such as current TLS requirements, and keep third-party SDKs compliant with App Store review rules, including privacy manifests.
How to Choose the Best Objective-C Development Company
Technical Expertise and Portfolio
Ask for examples of Objective-C apps they maintained, not only new Swift builds. Interview the developers who would join your project and ask about memory management, the Objective-C runtime, and debugging crashes from symbolicated logs.
Industry Experience
Vendors with experience in your industry understand its compliance needs. Healthcare apps may require HIPAA safeguards, and fintech apps often need PCI DSS awareness and strong encryption.
Development Process and Communication
Look for a clear process: code audit, roadmap, sprint cadence, release management and reporting. Time-zone overlap and a named technical lead matter more on legacy projects, because undocumented behavior surfaces often.
Pricing and Engagement Models
Fixed price suits a well-scoped audit or migration phase. Time and materials suits ongoing maintenance. A dedicated team works best when the app is a core product with a long roadmap.
Objective-C Development Costs in 2026
Objective-C specialists are scarcer than Swift developers, so rates are often 10 to 20 percent higher than general iOS rates. The figures below are market estimates.
| Region | Typical Hourly Rate (USD) |
|---|---|
| USA and Canada | $100 – $180 |
| Western Europe | $80 – $150 |
| Eastern Europe | $40 – $80 |
| Latin America | $40 – $75 |
| India and Southeast Asia | $25 – $50 |
| Project Type | Estimated Cost (USD) | Typical Timeline |
|---|---|---|
| Code audit and modernization roadmap | $5,000 – $20,000 | 2 – 4 weeks |
| Ongoing maintenance retainer | $3,000 – $15,000 per month | Ongoing |
| Partial migration to Swift | $30,000 – $120,000 | 3 – 6 months |
| Full migration of a large app | $120,000 – $400,000+ | 6 – 18 months |
Cost drivers include codebase size, test coverage, number of third-party dependencies, backend complexity and compliance requirements.
Why Hire an Objective-C Development Company?
Hiring a specialist company reduces the risk of breaking an app your customers already rely on. You gain developers who can read old code fluently, a structured migration plan, and the capacity to keep shipping updates while modernization happens in the background.
It also solves a hiring problem. Fewer developers learn Objective-C today, so building an in-house team for legacy work is slow and expensive. For a wider view of the languages and platforms outsourcing vendors support, see our technology guides.
FAQs About Objective-C Development Companies
Is Objective-C still used in 2026?
Yes. Apple still supports Objective-C in Xcode, and many established iOS and macOS apps contain large Objective-C codebases. New projects usually start in Swift.
Should I migrate my Objective-C app to Swift?
In most cases, yes, but gradually. Migrate the parts you change most often first, and keep stable modules in Objective-C until there is a business reason to move them.
How long does an Objective-C to Swift migration take?
Small apps can be migrated in two to three months. Large enterprise apps often take six to eighteen months when done incrementally alongside feature work.
Can Swift and Objective-C code run in the same app?
Yes. Xcode supports mixed-language targets, so Swift can call Objective-C through a bridging header, and Objective-C can call Swift code exposed to the Objective-C runtime.
How much does it cost to hire an Objective-C developer?
Rates range from about $25 per hour in India to $180 per hour in the U.S. Specialist legacy skills usually cost more than general iOS development.
What should I prepare before contacting a vendor?
Share repository access or a code sample, your current crash and performance metrics, your target iOS versions, and your business goals. This lets vendors give accurate estimates.
