What is the next Google Play deadline?

The deadline of November 1, 2026 is the end of the extension window for the target API 36 and Billing Library 7 deadlines. After that, the next one is February 1, 2027, when Google says app updates that don't support 16 KB memory page sizes can't be released.

What Xcode version does the App Store require?

Apple's upcoming requirements page says that since April 28, 2026, apps uploaded to App Store Connect must be built with Xcode 26 or later using an SDK for iOS 26, iPadOS 26, tvOS 26, visionOS 26 or watchOS 26. As of October 18, 2026, the page lists no Xcode 27 requirement.

Do these deadlines apply to apps already published?

It depends on the rule. Google says existing apps must target API 35 or higher to stay available to new users on newer Android versions, and existing apps keep working on version 7 of Play Billing until you ship an update. Most upload-side rules, such as the Xcode SDK minimum, apply when you submit a new build.

Which deadlines affect a Flutter app?

Nearly all of the Apple and Google Play rows do, because a Flutter app is a normal iOS and Android app underneath. The Firebase rows apply only if you use that Firebase product. The Supabase row applies only if you use Supabase.

How will I know if a date changes?

Each row links to the page where the platform states the date, and I list the date I checked it. Dates can move, so check the linked page before you plan around one. I update this page when a platform changes a date.

Key takeaways

Most 2026 deadlines have already hit. Since April 28, 2026 iOS uploads need Xcode 26 or later, and since August 31, 2026 Google Play needs new apps and updates to target API 36 and use Play Billing Library 8.
Google lets you request an extension for both Play deadlines until November 1, 2026. That is the last date to ship an update if you are still behind.
The next hard date for Android is February 1, 2027. Google says updates that don't support 16 KB memory page sizes can't be released after that.
On iOS, apps built with Xcode 27 must use the UIScene life cycle or they fail to launch. Xcode 27 was released on September 14, 2026.
Firebase has five shutdowns between March 22 and September 30, 2027. Core services such as Firestore and Authentication are not on the list.

The App Store and Google Play requirements that affect mobile app owners in 2026 and 2027 fit in one table: Xcode 26 uploads since April 28, 2026, target API 36 and Play Billing Library 8 since August 31, 2026, 16 KB page size support from February 1, 2027, and five Firebase shutdowns between March 22 and September 30, 2027. The table below is sorted by date, and every row links to the page where the platform states it.

I checked each one on October 18, 2026. Rows whose date has passed are marked "In effect".

Disclosure: App369 is my studio. I build and fix Android and iOS apps, mostly in Flutter, and the last section mentions what I sell. Apple and Google don't pay me for anything on this page.

Two more notes. Apple's privacy manifest rules (May 1, 2024 for required reason APIs and February 12, 2025 for common SDKs, see the privacy manifest guide) and the FCM legacy send shutdown (July 22, 2024, see the FCM migration guide) already passed before 2026. I keep them in their own guides because they still cause upload and delivery errors.

Apple

Apple's page names one build rule that matters most: Xcode 26 or later since April 28, 2026. As of October 18, 2026, it lists no Xcode 27 upload requirement. The bigger change with Xcode 27 is the UIScene life cycle, which a Flutter app on 3.41 or later with an unmodified AppDelegate gets automatically. A custom AppDelegate needs manual changes. The guides are ITMS-90725 and Xcode 26, UIScene and Xcode 27 and privacy manifest errors.

My advice: check which Xcode your build machine uses before your next upload, and test a build with Xcode 27 before you need one.

Google Play and Android

The Play rules come in pairs. Target API 36 and Billing Library 8 both took effect on August 31, 2026 with an extension to November 1, 2026. After that, February 1, 2027 brings the 16 KB page size rule, and on August 31, 2027 Google requires Billing Library 9 or later for new apps and updates. Separately, Android developer verification started on September 30, 2026 in four countries, with a global expansion in 2027. The guides are target API 36, 16 KB page size, Billing Library 8 and developer verification.

My advice: if you are still behind on API 36 or Billing 8, ship that update before November 1, 2026. Then do the 16 KB check before February 1, 2027, since it is the next date that can block a release.

Firebase and Google APIs

Firebase has five shutdown dates in 2027, plus the January 1 cutoff for new users of the InstanceId APIs. Firestore, Authentication, Cloud Functions and Hosting are not on the list. Google Fit APIs are supported only until the end of 2026, and Google points to Health Connect and the Google Health API. The legacy Fitbit Web API goes first: Google says it will be turned off on October 30, 2026. The guides are Firebase shutdown dates, FCM HTTP v1 migration, Google Fit to Health Connect and, if you use it, Supabase new table permissions.

My advice: open the Firebase console for every project you own and look at Extensions, Machine Learning, Test Lab and Studio. Those are the products with a date attached.

How I keep this page current

Every row links to the page where the platform states the date. If a source says only a month or "later this year", I write exactly that. When a platform moves a date, I change the row and the updated date at the top of this page. If you spot a date that looks wrong, tell me.

If one of these deadlines lands on an app you can't update yourself, the App Fix Ticket covers it in two fixed-price steps. A $450 Diagnosis gives you the root cause with evidence and a fixed repair quote within 3 business days, credited toward the fix. If you go ahead, the $1,200 Fix takes 5 business days and comes as a pull request. Or send me a short description.
