iPhone running a native iOS app built with Swift

iOS app development company in India

iPhone users notice everything. So do we.

A slightly laggy scroll, a button in the wrong place, a screen that ignores Dark Mode. iPhone owners spot it, and they're often the customers who spend the most. Softfix builds native iOS apps in Swift that feel like they belong on the phone, and gets them through Apple's review the first time.

Native iOS vs cross-platform app development

Is native iOS worth the extra cost?

Often not. Flutter or React Native puts you on both stores for less. Native Swift is worth it when iPhone users are your main market or the app must feel premium.

Go native iOS when…

Your buyers are mostly on iPhone
You want widgets, Live Activities or Apple Watch
You use HealthKit, ARKit or Core ML
Polish is part of your brand

Go cross-platform when…

Android matters just as much
Budget is tight
It's mostly forms, lists and payments
You need to launch fast

Swift vs Objective-C app development

Swift for everything new. Objective-C when we inherit it.

Swift app development and SwiftUI app development for new apps. Existing Objective-C apps keep running, with Swift added bit by bit.

	Swift / SwiftUI	Objective-C
Readability	Clean, modern syntax	Verbose, older style
Safety	Optionals and strong typing catch bugs early	More room for runtime crashes
New Apple features	Widgets, Live Activities, watchOS first	Possible, but awkward
Hiring developers	Easy	Getting harder each year
Our pick	All new apps	Maintaining or migrating older apps

Apple App Store review and compliance process — Pre-submission

The usual rejection reasons, checked first

Wrong payment method

Digital content must go through Apple's in-app purchase; physical goods and services can use Razorpay or Apple Pay. We set it up the right way round.

Missing privacy details

Privacy labels · clear permission prompts · tracking consent · in-app account deletion.

Login issues

Sign in with Apple where it's required, and a working demo account for the reviewer.

"Not enough functionality"

How to choose an iOS app development company

Four things worth checking

01

Download their iOS apps. Do they feel like iPhone apps, or Android apps in disguise?

02

Ask about SwiftUI. A current team should be comfortable with it.

03

Ask about their last rejection. Everyone gets one eventually. How they handled it tells you a lot.

04

Check the developer account. The app should live under your Apple account, not theirs.

FAQ

iOS questions people ask us

How much does iOS app development cost?

That really comes down to how many screens you need, which Apple features you use (like HealthKit or in-app purchases) and what the app connects to. An app just for iPhone is a lot cheaper than one that also runs on iPad and Apple Watch. Tell us about it on a call and we'll email you a full cost breakdown.

Should I use Swift or Objective-C for my iOS app?

Go with Swift if you're starting a new app. If you already have an Objective-C app that works fine, you don't need to rewrite it. We can keep it running and build new features in Swift.

Why choose an iOS app development company in India?

Mainly cost. Our Swift developers charge less than teams in the US or UK, and our working day overlaps with European hours and the US morning, so calls are easy to set up. We work out of Lucknow.

How long does Apple take to approve an app?

In most cases Apple replies within a day or two, though sometimes it takes longer. If an app gets rejected, that adds a few more days, which is why we go through Apple's common rejection reasons before we submit.

Do I need my own Apple Developer account?

Yes, so the app is owned by your company. We help with enrolment and the D-U-N-S number.

Who owns the app and source code?

You do. Code, certificates, App Store listing and backend are assigned to you in the contract.
