iOS Apps
iOS users pay for quality and punish its absence. We build for the standard they hold, not the minimum that ships.
iOS Apps built by RedSage are native-grade products: Swift-first engineering, interfaces that respect the platform's conventions, and the performance polish Apple users treat as table stakes. We handle the full arc - architecture, build, App Store review, and release.
The differentiator is discipline: memory and battery profiles measured, accessibility implemented rather than claimed, and review rejections engineered out before submission instead of negotiated after.
The Challenge
iOS projects fail in predictable places: an interface that fights platform conventions, review rejections that delay launch by weeks, performance that degrades as features accrete, and a codebase so tangled that every new iOS version becomes an emergency.
The App Store is unforgiving in both directions - Apple's review on one side, and users who delete after one janky session on the other.
Our Approach
We build with the platform, not against it: Swift and SwiftUI where they fit, UIKit where it earns its place, and interface conventions that make the app feel native because it is.
Quality gates are continuous: performance profiles on real devices, accessibility audits, and App Store compliance checked through development - so submission is a formality, not a negotiation. Release runs staged, with monitoring from the first cohort.

Frequently Asked Questions
Both, chosen per screen. SwiftUI is the default for new work; UIKit stays where its control is genuinely needed. Dogma costs more than pragmatism here.
By engineering compliance in from the start - privacy disclosures, permission justifications, and guideline constraints are checked continuously through development. Submission becomes a formality.
Yes. We audit the codebase, crash history, and review record first, then stabilize and roadmap. Objective-C and hybrid codebases are familiar territory.
