IOS app development

For founders and service businesses that need a native iPhone or iPad app, we scope, design, build in Swift and prepare the App Store submission.

  • Native Swift development for iPhone and iPad
  • Written scope document before any coding starts
  • TestFlight builds shared for review on real devices

Quick answer

iOS app development is the process of planning, designing, building, testing and publishing a native app for Apple devices such as the iPhone and iPad. Pugmarks Media builds these apps in Swift, shares test builds on real devices, and prepares the App Store submission after a written scope is agreed.

01Overview

What is iOS app development?

iOS app development is the work of building software that runs natively on Apple devices, mainly the iPhone and iPad. The app is written for Apple's operating system, usually in the Swift programming language, and is distributed through the App Store.

A concrete example: a physical therapy clinic wants patients to book sessions, get reminders and check in from their phones. An iOS app can handle the booking flow, send push notifications and let patients sign in with Face ID. The clinic's staff see the same bookings in a back-end system.

Native means the app is built specifically for one platform. It can use device features such as the camera, Face ID and Apple Pay directly, and it follows the design conventions iPhone users already know. Other mobile app platforms, such as Android, need a separate build or a cross-platform approach.

Most projects move through the same stages: scoping, design, development, testing and App Store submission. Developers typically work in Xcode, Apple's own development environment, and share test builds through TestFlight so you can try the app on real devices before release.

If you are still choosing between platforms, our pages on Android app development and cross-platform app development explain how those routes differ. The wider mobile app development service page covers how we approach all three.

02Fit

Who iOS app development is for

Founders launching a first iPhone product

Founders with a validated idea but no technical team get a written scope, clickable prototypes and a Swift build. We keep the first version focused so it can reach the App Store sooner.

Service businesses moving bookings to mobile

Clinics, salons and studios that lose time to phone bookings get an app with scheduling, push reminders and sign-in. Staff see the same bookings in a back-end system.

Companies whose customers mostly use iPhones

Teams selling to audiences where iPhones dominate, such as many US buyers, get a native app that follows Apple's Human Interface Guidelines. Check your own analytics to confirm.

Businesses with a web app or an outdated iOS app

Owners whose current product feels slow or dated get a native rebuild plan covering design, device testing and updated App Store listing details.

Teams needing Apple device features

Product teams that need Face ID, push notifications or camera access get native Swift code, TestFlight builds on real devices and a QA report per release.

Owners unsure whether to go iOS-first

Buyers comparing platforms can discuss the trade-offs with us, including our cross-platform app development and Android app development services.

03Scope

What's included

  1. Written scope documentA feature list, user flows and out-of-scope items agreed before coding starts. Founders and business owners use it to compare timelines and keep the first release focused.
  2. Apple-guideline UX and UIWireframes and screen designs that follow Apple's Human Interface Guidelines. You review clickable screens and edge cases before developers begin, which reduces rework during the build.
  3. Native Swift developmentApps written in Swift for iPhone and iPad, delivered in working increments. Suited to teams that need device features such as push notifications and Face ID sign-in.
  4. TestFlight review buildsTest versions shared through TestFlight so you and your staff can try the app on real devices each sprint and give feedback while changes are still inexpensive.
  5. Device and iOS QATesting across devices and iOS versions, with a report listing issues found and fixed. Product owners get evidence of what was checked before each release.
  6. App Store submission supportListing assets, privacy details and review submission handled with you. Teams new to Apple's publishing process get guidance on what the review requires.

04Process

How our iOS app development works

6 steps. You always know what's next.

The same path for every engagement.

  1. 11-3 days (estimate)

    Hold a scoping call

    We discuss your idea, target users and must-have features. You share goals, any existing designs and your backend or API details. You receive a short list of open questions and a proposed approach.

  2. 2About 1 week (estimate)

    Write the scope document

    We turn the call into a feature list, user flows and out-of-scope items. You review and approve it. You receive a written scope that keeps the first release focused before any coding starts.

  3. 31-3 weeks (estimate)

    Design screens to Apple guidelines

    Our designers create wireframes and screen designs that follow Apple's Human Interface Guidelines. You review clickable prototypes and edge cases, and you receive signed-off designs after revision rounds.

  4. 4Sprint-based; scope-dependent

    Build the app in Swift

    Developers write the native iPhone and iPad app in sprints, including integrations and device features such as push notifications. You give timely feedback and receive working increments instead of one late handover.

  5. 5Runs alongside each sprint

    Test on real devices

    We share TestFlight builds so you can try the app on real iPhones. Our team tests across devices and iOS versions. You receive a QA report listing issues found and fixed.

  6. 61-2 weeks, plus Apple review (estimate)

    Submit to the App Store

    We prepare listing assets, privacy details and the review submission. You provide your Apple developer account access and brand copy. You receive a submitted app and support through Apple's review feedback.

FAQ

Frequently asked questions

Still have a question?

Ask us directly. We reply with honest next steps, even if that means we're not the right fit.

Ask our team
How long does it take to build an iOS app?

Most iOS apps take from a few weeks to several months, depending on scope. The number of screens, integrations and review rounds drive the timeline. We write a scope document first, then give a phased plan with estimated durations for design, build and testing. Timings are estimates, and App Store review adds time at the end.

How much does it cost to develop an iOS app?

The cost depends on scope: the number of screens and features, backend or API work, design depth and how many App Store review cycles are needed. We scope each project in writing before coding starts, so you see what is included. Contact us with your idea, or see the pricing page for how we structure fees.

Should I build an iOS app or an Android app first?

Build for the platform your customers mostly use. If your buyers are largely on iPhones, as in many US markets, iOS first is often sensible. If your audience is mixed or global, compare it with Android app development or cross-platform app development before deciding.

Do I own the code and the app after it is built?

Yes, you own the code we write for you once the project is paid in full. Open-source libraries stay under their own licences. At handover you receive the source code and repository access, so you can maintain the app with another team later if you choose.

What do I need to start an iOS app project?

You need a clear idea, a description of your target users and a rough list of must-have features. Existing designs and details of any backend or API are helpful but not required. We start with a scoping call, then turn it into a written scope you approve before any coding begins.

Can I try working with you before committing to a full project?

Yes, we offer a pilot: a short, fixed-scope project that shows how we work. The scope, deliverables and timeline are agreed in writing up front, and there is no obligation to continue afterward. Ask us whether a pilot suits your app when you get in touch.

Do you handle App Store submission?

Yes, we prepare the App Store submission as part of the project. Apple reviews every app, and it can request changes, so review cycles affect timing. We share TestFlight builds on real devices beforehand so you can check the app before it goes to review. Approval is decided by Apple and cannot be guaranteed.

Can you build an iOS app for a healthcare business?

Yes, we build apps for healthcare, though they carry extra privacy and regulatory considerations that vary by jurisdiction. Your own legal or compliance advisers should review requirements. See our healthcare app development page for more detail.
