It depends on whether your app leans on iOS-specific hardware or ecosystem features HealthKit, Apple Pay, ARKit, Apple Watch integration or needs day-one access to new Apple APIs. If none of those apply and reaching both iOS and Android quickly with one team matters more, cross-platform development is usually the more efficient path.

Cost scales with feature complexity, device/OS version coverage, and how much custom HIG-compliant design the app needs, rather than a flat per-screen rate. An MVP with standard UI patterns costs meaningfully less than a medium-complexity app with custom design and integrations, which costs less again than a complex app requiring deep Apple framework work.

 Timeline follows the same complexity drivers as cost an MVP with core flows and standard components moves fastest, while apps needing deep Apple framework integration or support across many iOS versions take meaningfully longer, partly due to added testing time and App Store review cycles.

SwiftUI generally suits new projects wanting faster iteration and Apple’s current recommended approach, while UIKit remains relevant for complex legacy codebases or specific fine-grained control SwiftUI doesn’t yet fully expose. Many production apps use a hybrid of both rather than treating it as an exclusive choice.

Every new app and every update goes through Apple’s review process, which checks against safety, performance, business, design, and legal-compliance guidelines before approval. Review timelines vary, and submitting a build with unclear pricing, unjustified permissions, or incomplete privacy disclosures is the most common cause of an avoidable rejection and delay.

Hidden or unclear subscription and pricing terms, permissions requested without a clear in-app justification, and apps that don’t demonstrate genuine native value (like a bare web-view wrapper) are the most frequent, well-documented rejection patterns. Most of these are avoidable with review-aware planning before submission, not fixes made after a rejection.

Yes, migrating from Objective-C to Swift, or from UIKit to SwiftUI, is typically done incrementally against a defined feature-parity checklist rather than as a single risky rewrite. The right approach depends on how much of the existing codebase is worth preserving versus how much has accumulated technical debt that makes a phased rebuild faster.

Two things dominate: handling Apple’s annual iOS version upgrades and the API deprecations that come with them, and managing App Store re-review on every update rather than treating it as a one-time launch event. Falling behind on either creates a compounding problem — an app left too many iOS or Xcode versions behind can eventually be blocked from submitting updates at all.

 Yes, watchOS app development — whether a companion app to an iPhone app or a standalone Apple Watch experience — is part of our native iOS work, particularly relevant for fitness, health, and quick-glance use cases where a phone pickup is the wrong interaction model.

Yes, Apple has been expanding on-device AI capabilities available to developers, including Apple Intelligence integration and Foundation Models access for building AI-driven features without sending data to external servers. Specific capabilities available to your app depend on current Apple platform APIs and the iOS versions your app supports, which is worth scoping early with our AI development team if on-device AI is a core feature.

Following a US court decision in the Epic Games dispute, Apple updated its guidelines to allow apps in the US storefront to include buttons and external links directing users to payment options outside Apple’s in-app purchase system. This is a meaningful, relatively recent shift from Apple’s earlier, stricter requirement that all digital purchases go through StoreKit, and it’s worth factoring into monetization planning if your app serves US users primarily.
