[webview_flutter_wkwebview] Require iOS 15 / macOS 12 and drop deprecated SecTrustGetCertificateAtIndex code path by jmagman · Pull Request #13294 · flutter/packages

jmagman · 2026-10-16T20:02:13Z

Pick up the iOS 15 minimum from the previously-updated Flutter 3.47. Remove old availability checks. This removes usage of SecTrustGetCertificateAtIndex which was deprecated in iOS 15.
Also hitting deprecation 'webView(forIdentifier:withPluginRegistry:)' is deprecated: Use webView(forIdentifier:withPluginRegistrar:) instead. in FWFWebViewFlutterWKWebViewExternalAPITests. Mark the two tests as @available(*, deprecated) to suppress, and so the tests are still run since the deprecated API is public.

This wasn't showing up in CI due to flutter/flutter#194517.

Fixes flutter/flutter#194585

…ated SecTrustGetCertificateAtIndex code path

jmagman · 2026-10-16T20:12:19Z

override: no versioning needed: the webview_flutter change is README‑only

jmagman · 2026-10-16T20:13:10Z

-
-  // Overridable for testing.
-  internal func secTrustGetCertificateAtIndex(_ trust: SecTrust, _ ix: CFIndex) -> SecCertificate? {
-    return SecTrustGetCertificateAtIndex(trust, ix)


This was the deprecated API, it was only used in a availability fallback so remove it.

Code Review

This pull request updates the minimum supported iOS version to 15.0 and macOS version to 12.0 for the webview_flutter_wkwebview package, removing pre-iOS 15/macOS 12 fallback code paths, availability checks, and deprecated methods. Feedback on the changes points out that releasing this as a patch version (3.27.1) without updating the Dart SDK constraint or performing a major version bump will break builds for users on older Flutter versions. Additionally, a suggestion was made to simplify the copyCertificateChain method in SecTrustProxyAPIDelegate.swift using a conditional cast and map to avoid force-casting.

Heads up: this breaks SwiftPM builds for apps that also use google_mobile_ads. Its Package.swift still declares iOS 13 and depends on the webview-flutter-wkwebview product, so Xcode fails with:

The package product 'webview-flutter-wkwebview' requires minimum platform version 15.0 for the iOS platform, but this target supports 13.0 (in target 'google_mobile_ads' from project 'google_mobile_ads')

It took down the four Mac_ios platform_views_scroll_perf_* builders on flutter/flutter master once the pub roller picked up 3.27.1 (https://ci.chromium.org/b/8667465549370430577). I'm pinning the framework to 3.27.0 in flutter/flutter#194864 for now; the real fix needs to happen on the google_mobile_ads side (its latest release, 9.1.0, has the same iOS 13 floor).

`webview_flutter_wkwebview` 3.27.1 (flutter/packages#13294) raised its Swift package floor to [iOS 15](https://github.com/flutter/packages/blob/1c44dbf537a533f2abc96291e5c52f5e3cb5d691/packages/webview_flutter/webview_flutter_wkwebview/darwin/webview_flutter_wkwebview/Package.swift#L12). `google_mobile_ads` still declares [iOS 13](https://github.com/googleads/googleads-mobile-flutter/blob/ea70f22f17ed3c275e443a8d2dcbdd7fe0cf1cbf/packages/google_mobile_ads/ios/google_mobile_ads/Package.swift#L9) and depends on the [`webview-flutter-wkwebview` product](https://github.com/googleads/googleads-mobile-flutter/blob/ea70f22f17ed3c275e443a8d2dcbdd7fe0cf1cbf/packages/google_mobile_ads/ios/google_mobile_ads/Package.swift#L17-L24), so SwiftPM refuses to build any app that has both. `dev/benchmarks/platform_views_layout` is one of those apps, which took down the four `Mac_ios platform_views_scroll_perf_*` builders since flutter#194819: ``` Target Integrity (Xcode): The package product 'webview-flutter-wkwebview' requires minimum platform version 15.0 for the iOS platform, but this target supports 13.0 ``` Example CI failures: - https://ci.chromium.org/b/8667465549370430577 - https://ci.chromium.org/b/8667466129370978161 This pins `webview_flutter_wkwebview` to 3.27.0 until `google_mobile_ads` raises its minimum iOS version to 15 (its latest release, 9.1.0, still declares iOS 13).

Revert part of #13294 that updated the iOS and macOS versions. Re-add the availability checks. Still fix the `SecTrustGetCertificateAtIndex` deprecation issue. Due to Swift Package Manager issue flutter/flutter#194864, this broke plugins with dependencies targeting lower versions.
