Apple Developer: App Store submissions open for iOS 27 etc. (Xcode 27 RC, asset previews, and April 2027 SDK gates)

Original post (source): Apple Developer News - “App Store submissions now open for the latest OS releases” (Sep 9, 2026)

The headline

Apple is basically telling teams: “ship your iOS 27 build now, and treat store assets, age rating questions, and Mac architecture as release dependencies.”

What Apple is prompting teams to do

• Use Xcode 27 Release Candidate to build against the latest SDKs, then test via TestFlight and submit for review.
• Plan for macOS 27 being Apple silicon only. Apple reiterates that macOS 26 is the final Intel + Rosetta release, and suggests setting build architecture to arm64 only if you want to drop Intel.
• Answer the age rating questionnaire accurately. They call out Time Allowances and the need to indicate social media capabilities in App Store Connect.
• Prepare for new creative surfaces. Product page headers and search result assets are coming, and Apple points to templates and guidance. They also mention an upcoming product page preview tool in App Store Connect.
• Watch the next SDK gate: starting April 2027, uploads need to be built with the iOS 27 SDK (and equivalents for other OSes).

Why this matters

This is not just “platform news”. It creates a bunch of failure modes that show up as growth issues:

• a broken Mac build becomes support tickets and bad reviews
• wrong age rating answers can create submission friction or region-specific surprises
• new creative placements land, and your assets suddenly feel dated

Tiny win

Make a one-page “Fall release checklist” and assign owners:

1. Xcode RC build and TestFlight sanity pass
2. Mac architecture decision (universal vs arm64 only)
3. Age rating questionnaire answers (especially social/UGC surfaces)
4. A lightweight asset plan for the new headers/search results formats
