iOS App Development

iOS users spend more inside apps than Android users, and Apple's App Store is also the stricter of the two: guideline 4.2 alone rejects anything that is only a repackaged website. I build native iOS apps in Swift that pass review on the first try, using Apple's latest frameworks to deliver the smooth, polished experience iOS users expect.

What you get

1 Swift + SwiftUI

Modern Apple-native stack with 60fps animations and buttery-smooth transitions.

2 App Store submission

First-submission pass rate. I know what Apple reviewers look for.

3 HealthKit, Core Data, StoreKit

Deep iOS integration when your product needs it.

4 Apple Watch + iPad support

Optional but powerful. Universal apps done right.

5 Privacy-first architecture

Apple's privacy rules are strict. Your app will comply by design.

What Apple review actually checks

A rejection almost never relates to code quality. The recurring reasons are predictable: a test account that does not work or was never supplied, a permission requested with no written explanation, a feature advertised in the listing but missing from the app, a payment link routing around Apple's system, a privacy policy that does not match what the app does. Guideline 4.2 is the bluntest: an app that is only a repackaged website is rejected. That is prepared before submitting, not after the rejection.

The Apple ecosystem: when it is worth the detour

Apple Watch, iPad, widgets, Siri shortcuts: each is another app to design, test and maintain, not a checkbox. It is worth it when the use case genuinely asks for it — a metric checked on the wrist mid-effort, an input tool that gains from an iPad's surface. It is not worth it to show the same thing smaller. I would rather ship one iPhone app that does its job than four variants sharing the same testing budget.

Privacy is a design constraint, not a checkbox

On iOS, tracking a user across apps requires explicit permission, and a large share of people decline — a business model resting on that should know before a line is written. The store privacy label also has to describe exactly what the app collects, including through the third-party libraries added to it. Every permission needs an explanation string, and a vague one gets the app rejected. Better to decide early what you collect: it is also what makes GDPR simple.
