Change minimum iOS version from 8.0 to 9.0 #62902

jmagman · 2020-08-04T20:34:38Z

Description

Update create app and module templates to iOS minimum version 9.0.
Updated example projects manually. Will hold off on integration tests until know know if we can do it automatically with #62880

This does not update the plugin template podspec minimum version. To be discussed separately.

Related Issues

Fixes #60035

Tests

Updated -miphoneos-version-min calls.
App creation and example build integration tests cover part of this.

Note these newly created plugins will not be able to be used by Flutter apps with a minimum of 8.0 (compilation time error), so that's all apps currently in the wild now.

I really wish there wasn't an error for this, or at least I wish it was suppressible.

I'm willing to be convinced we shouldn't increase the plugin minimum requirement for a few stable cycles until more apps have upgraded to 9.0...

so you're saying an app can't use a plugin with a higher minimum ios version?

Yes. I'm going to revert the plugin min version bump, it seems like we need to talk about that separately.

This means we're intentionally not changing ios_workflow in this PR?

This means we're intentionally not changing ios_workflow in this PR?

This PR is to prevent the "IPHONEOS_DEPLOYMENT_TARGET too low" warning that happens when you target 8.0 in Xcode 14.

Are you think of #62883 maybe?

xster · 2020-08-06T19:13:34Z

Yes, my comment makes no sense :D
Please disregard. LGTM

PiN73 · 2020-10-20T21:44:07Z

As it breaks building of existing apps for iOS (see issue), there should be a notice in breaking changes page saying to modify ios project, shouldn't it?

PiN73 · 2020-10-20T22:44:15Z

Also if I understood correctly, Flutter now supports iOS 9.0 and later, not 8.0 as before, this should be fixed at Build and release an iOS app page

jmagman · 2020-10-21T02:09:36Z

@PiN73 Flutter supports iOS 8, but the default for a new app is now iOS 9 to avoid Xcode 12 warnings.

1. Change templates to `IPHONEOS_DEPLOYMENT_TARGET`, `MinimumOSVersion`, and Podfile `platform :ios` to 12.0. 2. Add migrator for Podfile part to migrate `platform :ios, '11.0'` -> `platform :ios, '12.0'` 3. Compile with `-miphoneos-version-min=12.0` 4. Run the migrator on all example apps and integration tests. See also #62902 and #85174 and #101963 Fixes #136060

This updates the Flutter minimum iOS version from 12.0 to 13.0, adds a migrator for existing apps, and updates our own examples, tests, and benchmark apps to 13.0. A follow-up patch will drop iOS 13 `@available` checks in the embedder. This is required in order to use Swift in the embedder and not need to bundle the Swift runtime libs in every app that uses Flutter. Swift stable ABI As of March 2025, usage of iOS is well below 1%, see example public usage data here: https://telemetrydeck.com/survey/apple/iOS/majorSystemVersions/ This patch makes the following changes: 1. Updates ios_deployment_target from 12.0 to 13.0. 2. Changes templates to `IPHONEOS_DEPLOYMENT_TARGET`, `MinimumOSVersion`, and Podfile `platform :ios` to 12.0. 3. Adds migrator for Podfile part to migrate `platform :ios, '11.0'` -> `platform :ios, '12.0'` 4. Compiles with `-miphoneos-version-min=12.0` 5. Runs the migrator on all example apps and integration tests. 6. Updates examples, tests to iOS 13 deployment target It also updates `verify_exported.dart`: * iOS 13 introduces stricter separation of const and non-const global symbols. Previously, these were declared in the Mach-O `__DATA` section which may be mapped read-write, but now they're in a dedicated `__DATA_CONST` section which is mapped read-only. This adds `(__DATA_CONST,__const)` to the allowlist with the same enforcement on exported symbol naming as before.
