The iOS 27 Rebuild: What Agencies Are Charging For Right Now
Not financial advice. Verify claims independently.
September 14 forced a rebuild wave. What the work actually involves — and what it should cost.
Since iOS 27 shipped two weeks ago, every client with a React Native or native iOS app has been through the same conversation: "does our app work on 27?"
The actual work:
- Scene lifecycle migration (mandatory — old lifecycle deprecated)
- Resizable layout audit (iPhone apps must flex now)
- App Intents for the new Siri
- App Store creative assets (new header + search-result formats)
What it should cost: a well-architected app needs 1–2 weeks. An app held together with hard-coded dimensions needs 4–6 — the migration is cheap, fixing the layout debt isn't.
The trap: agencies quoting 8+ weeks for the "iOS 27 migration" are billing for their previous technical debt. Ask what specifically breaks before you approve the invoice.
Stock Picks's iOS 27 build shipped in 6 days — that's the baseline.
