Build notes, architecture decisions, and the occasional hard-won lesson from shipping native iOS, Android, and server-side Swift.
The PreferenceKey snippet everyone copy-pastes silently reports a frozen 0.0 — and the coordinate space isn't why. Here's the fix, plus scrollPosition(id:) and onScrollGeometryChange.
Feedback scattered across App Store reviews, email and TestFlight isn't a collection problem — it's a loop problem. Here's how to build the loop in SwiftUI.
iOS gives you strong defaults and then stops. Where the platform's guarantees end and yours begin: Keychain and the Secure Enclave, App Attest, ATS and pinning, data-at-rest protection classes, privacy manifests, why jailbreak detection is not a control, and what auditors actually ask.
"Every business needs an app" is a sales pitch, not an answer. What mobile actually changes for a small or mid-sized business, what drives the cost, and how to tell whether you're one of the companies that shouldn't build one.
Seven local packages, one Vapor binary, four public domains. What splitting a Swift project into modules actually buys you, the rule that makes it work, the bug it did not prevent, and when not to bother.
Six years on, this is not a choice between two frameworks — it is a ratio, and every app we ship has both in it. What SwiftUI still does badly, how to bridge in both directions, and how to pick per project.
Swift and MongoDB are not alternatives — but there is a real decision hiding behind that search. Here's when Mongo beats Postgres for a Swift backend, why the old SwiftUI shortcuts are gone, and the wiring that still works.
Unified logging is the best-documented Apple API that almost nobody uses properly. Subsystems, the privacy rules that redact your strings, signposts, pulling logs off a device — and why the server wants a different Logger entirely.
The real sequence from an idea to a live listing: discovery, prototype, MVP, TestFlight beta, App Review, launch. Honest durations for each stage, what actually causes rejections, and the admin that has to start weeks before you think it does.
Not a flamewar. How Android and iOS genuinely differ as software, which platform gives you more accessible support, which app store is actually safer, and how to pick the right devices for a company fleet — from a studio that ships on both.
