Hire Remote iOS Developers (Swift & Objective-C)

Hire Senior iOS Developers Who’ve Shipped Top-Charts App Store Apps

Getting an iOS app into the App Store is easy. Building one that retains users, performs flawlessly on every device generation, and generates eight figures in revenue is a different engineering challenge entirely. The iOS developers you need — the ones who’ve architected SwiftUI apps at scale, integrated Core ML models, and shipped live service games and fintech platforms — are on our bench ready to join your team.

We match you with senior iOS developers who’ve shipped top-performing App Store apps for Fortune 500 enterprises, unicorn startups, and category-defining consumer products. Engineers who understand Swift deeply, not just its syntax — concurrency model, memory management, performance optimization, and the platform APIs that separate great apps from average ones.

Start in days, not months. Pay 50% less than equivalent US-based iOS talent.

What Our iOS Developers Build

Consumer iOS Applications

SwiftUI and UIKit apps for consumer markets — optimized for retention, App Store Review compliance, accessibility, and performance across the full device matrix from iPhone SE to iPhone Pro Max.

Enterprise & B2B iOS Applications

Complex enterprise apps with SSO, MDM deployment, offline-first architecture, background sync, and integrations with enterprise backends. Our engineers understand BYOD environments and enterprise deployment workflows.

Fintech & Regulated Industry Apps

Banking, investment, insurance, and healthcare iOS apps with biometric authentication, end-to-end encryption, secure enclave usage, PCI DSS and HIPAA-compliant data handling, and App Store Review navigation for regulated content.

Core Data, CloudKit & Offline-First Architecture

Local-first iOS applications with robust data persistence, iCloud sync via CloudKit, conflict resolution strategies, and background sync — apps that work whether or not the user has a signal.

ARKit, Core ML & Platform-Specific APIs

Augmented reality experiences with ARKit and RealityKit, on-device ML inference with Core ML and Vision framework, HealthKit integrations, and advanced platform APIs that leverage iOS hardware capabilities.

Client Success Story: Fintech App — Featured in App Store, $40M Series B

A Series A fintech startup building personal investment tools for millennials needed iOS engineers who could ship a beautiful, regulatory-compliant app fast enough to drive their Series B fundraise. Our iOS developers built a SwiftUI app with Plaid integration for account linking, custom charting using Swift Charts, biometric authentication with Face ID, real-time portfolio updates via WebSocket, and a zero-password onboarding flow that achieved 78% completion. The app launched to 50,000 users in its first week and was featured by Apple in the Finance category. The traction helped close a $40M Series B six months post-launch.

Client Success Story: Mobile Commerce App — 4.8★ Rating, $120M in Mobile Revenue

A mid-market retailer’s mobile app had a 2.9-star rating and a 34% checkout completion rate — well below industry benchmarks. Our iOS team rebuilt the app with a SwiftUI product browser featuring offline catalog browsing, a redesigned checkout flow with Apple Pay and biometric confirmation, a native loyalty rewards UI, and a Core Data-backed wishlist with push notification restock alerts. The app’s rating improved to 4.8 stars within 90 days of the rebuild. Checkout completion improved to 67%. Mobile revenue grew to $120M annually — from $43M before the rebuild.

Why Companies Choose Our iOS Developers

• Swift-native expertise: They write idiomatic Swift — async/await, actors, property wrappers, and SwiftUI the way Apple intended
• App Store experience: They know how to navigate App Store Review, avoid rejections, and optimize for discoverability
• Platform depth: ARKit, Core ML, HealthKit, StoreKit — they use iOS platform APIs to deliver experiences that web apps can’t match
• 50% cost savings: Senior iOS expertise at a fraction of US market rates
• Fast start: Most engagements begin within 1–2 weeks

Engagement Models

• Individual iOS Developer — One senior iOS engineer embedded in your team. Ideal for adding Swift/SwiftUI depth, Core Data architecture, or platform API expertise.
• iOS Development Pods (2–3 engineers) — iOS developer paired with a backend engineer and QA specialist. Common for full app builds or major feature development.
• Mobile Teams (3–8+ engineers) — Complete squads for enterprise iOS applications or consumer apps requiring rapid feature velocity.
• Contract-to-Hire — Evaluate a developer’s iOS output before committing long-term.

How To Vet iOS Developers

Our iOS vetting identifies engineers who understand the platform — not just Swift syntax.

1. Technical screening — Swift concurrency (async/await, actors, Sendable), memory management (ARC, retain cycles, weak/unowned), SwiftUI state management, UIKit-SwiftUI interoperability, and performance profiling (Instruments). Over 90% of applicants do not pass this stage.
2. Portfolio review — Live App Store apps they’ve shipped. We evaluate code architecture, UI quality, performance (via Instruments profiling if provided), and App Store ratings.
3. Live coding challenge — Build a SwiftUI view with proper state management, networking with async/await, and error handling. Evaluated on idiomatic Swift, testability, and UI correctness.
4. Communication screening — iOS developers work closely with designers and product managers. Clear cross-functional communication is essential.

What to Look for When Hiring iOS Developers

Strong iOS developers write Swift that uses the platform’s strengths — they don’t just port web patterns to mobile.

What strong candidates demonstrate:

• They discuss memory management proactively — they know how retain cycles form in closures and how to use weak references correctly
• They understand Swift concurrency at the structured concurrency level — actors, task groups, async sequences — not just “I replaced callbacks with async/await”
• They profile with Instruments routinely — they’ve diagnosed real memory leaks, main thread hangs, and Core Data performance issues
• They have App Store submission experience and understand App Store Review guidelines for their domain

Red flags to watch for:

• Writes Swift that looks like Objective-C or Java — no SwiftUI fluency, no modern concurrency patterns
• “It works on the simulator” — has never profiled on real hardware or across device generations
• No understanding of retain cycles — has caused memory leaks in production
• No App Store submission experience — has only worked on internal enterprise apps with no review process

Interview questions that reveal real depth:

• “Walk me through how you’d architect an offline-first iOS app where the user can browse and place orders without a network connection. What data model and sync strategy would you use?”
• “Describe a retain cycle you’ve encountered in a real app and how you diagnosed and fixed it.”
• “When would you choose UIKit over SwiftUI for a new feature? What are the specific trade-offs you’re accepting?”

Related Services

• Mobile App Developers — Full-spectrum mobile development including iOS, Android, and cross-platform.

• Full-Stack Developers — Full-stack engineers who can build both the iOS app and the backend API it depends on.
• DevOps & SRE Engineers — Infrastructure engineers who manage CI/CD pipelines, TestFlight automation, and backend services for your iOS app.
