What is an iOS Developer, and What Do They Do?
An iOS developer is a software engineer who designs, builds, tests, and maintains apps for Apple devices — iPhone, iPad, Apple Watch, and Apple TV. They write in Swift (Apple’s modern programming language) or Objective-C (used to maintain older codebases), build interfaces with SwiftUI or UIKit, and publish through the Apple App Store.
A strong iOS developer also understands Apple’s review rules, data handling, and how to connect an app to your backend. For Canadian businesses, that work usually also means privacy compliance (PIPEDA), Canadian payment options (Interac, Apple Pay), and — for many apps — French/English bilingual support.
How do I Hire iOS Developers? (The Three Channels)
There is no single “best” way to hire — there are three channels, each suited to a different project. Pick the one that matches your scope and how hands-on you want to be. Where Space-O fits: Space-O Technologies is a Canadian iOS app development company in the agency category. We provide dedicated iOS teams — full-time, part-time, or hourly — with a project manager, an NDA, and a 30-minute free consultation, backed by 300+ delivered projects and ISO 9001 / ISO 27001 certification.
Freelancers
Best for small features, bug fixes, UI polish, or an early MVP. You source them on open marketplaces such as Upwork (an open freelance marketplace where you review portfolios, ratings, and tech stacks before hiring). You manage the developer directly, which keeps cost low but puts the project-management burden on you. Independent rates typically run about $25–$85/hr.
Vetted Talent Networks
Best for scaling a team quickly with pre-screened, mid-to-senior engineers. Networks such as Toptal, Lemon.io, or Braintrust screen developers for technical skill and match you within a day or two, so you skip most of the interviewing. You pay a premium for the vetting, and you still coordinate the work.
Development Agencies
Best for non-technical founders and complex or enterprise apps that need designers, developers, and a project manager working as one team. An agency owns delivery end to end — discovery, design, build, App Store launch, and maintenance. Canadian agency engagements typically run $8,000–$50,000+ per project, or a monthly dedicated-team retainer.

Real benefits — 30-minute free consultation, NDA, a dedicated project manager, and flexible hiring models.
What Should I Look for When I Hire iOS Developers?
Whichever channel you choose, verify these competencies before you commit. Each one is a concrete skill the App Store and your users will depend on.
Swift, SwiftUI & Objective-C Proficiency
Swift and SwiftUI — Swift is Apple’s modern, safe language for new apps; SwiftUI is its declarative UI framework for building screens across all Apple devices with less code. This is the baseline for any new project.
Objective-C — an older language kept alive in legacy and deep-system code. A bonus, not a must, unless you have an older codebase.
UIKit, Core Data & Combine Knowledge
UIKit — the older, view-based UI framework. Most established business apps still rely on it, so a developer needs it to maintain or extend existing code.
Core Data (and Combine) — Core Data handles local, offline storage; Combine manages data flow and events. Both matter for apps that must work without a constant connection.
Xcode & Apple Human Interface Guidelines (HIG)
Xcode — Apple’s official IDE (the tool used to write, build, simulate, and debug iOS apps). Fluency here is non-negotiable.
Apple Human Interface Guidelines (HIG) — Apple’s design and structure rules. A developer must follow them or the app risks rejection at App Store review.
App Store Submission & Apple Developer Program
App Store submission experience — provisioning profiles, review guidelines, and a track record of approved apps. This is the step that most often delays first-time builders.
Apple Developer Program account — publishing requires an Apple Developer Program membership ($99 USD/year). Confirm who owns and manages it.
REST APIs & Backend Integration
REST APIs and backend integration — most apps exchange data with a server. Look for REST API, JSON, secure authentication (OAuth), and Firebase experience.
iOS Security & Canadian Compliance
Canadian security and compliance — Keychain, App Transport Security (ATS), and privacy permissions, plus PIPEDA (and PHIPA/HIA for healthcare apps).

FAQs About Hiring iOS Developers
What is an iOS developer?
An iOS developer is a software engineer who designs, builds, tests, and maintains apps for Apple devices — iPhone, iPad, Apple Watch, and Apple TV — using Swift or Objective-C, SwiftUI or UIKit, and the Apple App Store. They handle everything from interface to backend integration and App Store submission.
Can I hire someone to build me an app?
Yes. You can hire a freelancer for small work, a vetted talent network for pre-screened engineers, or an agency like Space-O for an end-to-end team. For a complete iPhone app most businesses choose an agency so design, development, project management, and App Store launch are handled in one place.
How much does it cost to hire iOS developers in Canada?
A simple app or MVP typically runs $8,000–$25,000, medium complexity $25,000–$50,000, and complex or enterprise apps $50,000+. Freelancers charge roughly $25–$85/hr; agencies use project pricing or monthly dedicated-team retainers. With Space-O, a simple iPhone app starts from $10,000.
How long does it take to build an iOS app?
A simple app takes about 2–3 months, medium complexity 3–6 months, and an enterprise-level app 6–12 months — including development, testing, and App Store submission.
What skills should an iOS developer have?
Swift and SwiftUI for new apps, UIKit for existing ones, Objective-C for legacy code, Core Data and Combine for data, Xcode as the IDE, REST API and Firebase integration, Apple Human Interface Guidelines knowledge, and a proven App Store submission record.
Can I build an iOS app for free or by myself?
You can learn Swift and use Xcode for free, and a free Apple developer account lets you build and test on your own device. But publishing to the App Store needs the $99/year program, and a polished, secure, store-ready app usually requires professional development.
Will developers work exclusively on my iOS project?
With a dedicated model, yes. Space-O’s dedicated developers work full-time on your project with direct communication, consistent velocity, and the ability to scale the team up or down as needs change.
Do you sign an NDA and protect my IP?
Yes. Space-O signs an NDA before project discussions, full IP ownership transfers to you, and source code and assets are delivered to you. Confidentiality is maintained throughout.
What iOS-specific features can you implement?
Face ID and Touch ID, Apple Pay, ARKit (augmented reality), Core ML (machine learning), HealthKit and HomeKit, SiriKit and Shortcuts, iCloud sync, push notifications via APNs, Core Location and MapKit, StoreKit in-app purchases, widgets, and App Clips.
Are your iOS developers compliant with Canadian regulations?
Yes. We build to PIPEDA and provincial privacy law, deliver healthcare apps to PHIPA (Ontario) and HIA (Alberta) standards with HealthKit, support Interac/Moneris/Apple Pay, and keep data on Canadian infrastructure where required.
How do I hire iOS developers from Space-O?
Fill out our contact form, and an iOS consultant will reply within 48 hours to discuss your idea and goals. We share matching developer resumes for you to interview, you choose an engagement model, we sign an NDA, and a dedicated project manager runs the project to App Store launch.
Where in Canada do you provide iOS developers?
Space-O works with businesses across Canada — Toronto, Vancouver, Calgary, Montreal, Ottawa, and Edmonton — building native iPhone and iPad apps tailored to local industries such as finance, retail, healthcare, travel, and education. Montreal projects can be delivered bilingually for Canada’s national market.
How do I communicate with hired iOS developers?
You get a dedicated project manager as your point of contact, plus direct communication with developers through email, Slack, Basecamp, and video calls, with regular updates and feedback cycles.
How do I hire the right iOS developer?
Define your scope, sign an NDA, review App Store portfolios in your industry, run a short technical check, and structure milestone payments tied to project phases. Verify core skills — Swift, SwiftUI, UIKit, Core Data, Xcode, Apple Human Interface Guidelines, and App Store submission experience.
What does the $99 Apple Developer Program get you?
The Apple Developer Program is a $99 USD/year membership that lets you publish apps on the App Store, access beta versions of Xcode and iOS, and use advanced capabilities such as CloudKit, Apple Pay, and push notifications. Publishing any app to the App Store requires it.
Do you build for iPad, Apple Watch, and Apple TV too?
Yes. We build iPad apps that use the larger screen and Apple Pencil, watchOS apps with complications and health integrations, and tvOS apps for the big screen — plus continuity features like Handoff and Universal Clipboard across devices.
How do I review your iOS portfolio?
Browse our iOS case studies — enterprise solutions, consumer iPhone apps, iPad-optimized apps, and watchOS work. Ask us for case studies specific to your industry.
What is the difference between a freelancer, a talent network, and an agency?
A freelancer is one independent developer you manage directly — cheapest, best for small tasks. A vetted talent network pre-screens engineers and matches you fast for a premium. An agency provides a full cross-functional team (designers, developers, project manager) and owns delivery end to end — best for complex or enterprise apps.
