iOS: Update minimum iOS version to 13.0 (#167737) 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.

Update platform shims in dev/manual_tests (#94616) Updates the platform shims in dev/manual_tests so that Windows and Linux can be built. I had to update the Windows shims, because I was unable to build a Windows app there. Also updates the analyze.dart script to report all license issues simultaneously instead of just dying after the first failure. The only substantive code changes are in dev/bots/analyze.dart and dev/bots/test/analyze_test.dart4 年前
[iOS] Migrate @UIApplicationMain attribute to @main (#146707) This migrates Flutter to use the @main attribute introduced in Swift 5.3. The @UIApplicationMain attribute is deprecated and will be removed in Swift 6. See: https://github.com/apple/swift-evolution/blob/main/proposals/0383-deprecate-uiapplicationmain-and-nsapplicationmain.md This change is split into two commits: 1. https://github.com/flutter/flutter/pull/146707/commits/ad18797428ccbcfc14c6875118c44842b689ed6d - This updates the iOS app template and adds a migration to replace @UIApplicationMain uses with @main. 2. https://github.com/flutter/flutter/pull/146707/commits/8ecbb2f29f419ed50fdebfbdcc069f3653638cc5 - I ran flutter run on each Flutter iOS app in this repository to verify the app migrates and launches successfully.
