webview_flutter_wkwebview 3.27.1 (flutter/packages#13294) raised its Swift package floor to iOS 15. google_mobile_ads still declares iOS 13 and depends on the webview-flutter-wkwebview product, 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 #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:

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).

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If both you and the PR author believe this PR qualifies for a test exemption, escalate to the tech lead for the changed area to review and apply the test-exempt label. All reviewers should feel empowered to ask for tests before escalating.

Detected the emergency label.

If you add the autosubmit label, the bot will wait until all presubmits pass but ignore the tree status, allowing fixes for tree breakages while still validating that they don't break any existing presubmits.

The "Merge" button is also unlocked. To bypass presubmits as well as the tree status, press the GitHub "Add to Merge Queue".

Code Review

This pull request downgrades the webview_flutter_wkwebview package from version 3.27.1 to 3.27.0 in pubspec.yaml and pubspec.lock, and adds it to the manually pinned dependencies in update_packages_pins.dart to prevent SwiftPM resolution failures. I have no feedback to provide.

'flutter_template_images': '5.0.0', // Must always exactly match flutter_tools template.
'material_color_utilities': '0.13.0', // Keep pinned to latest until 1.0.0.
'data_assets': '0.20.0', // Keep pinned to latest until 1.0.0. Rolled by @dcharkes.
// 3.27.1 requires iOS 15, but google_mobile_ads' Package.swift still declares

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.

Follow-up to flutter#194864 (stacked on
it until that lands).

Adds the tracking issue link next to the `webview_flutter_wkwebview` pin
so whoever unpins it knows what to check.

`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

This pins `webview_flutter_wkwebview` to 3.27.0 until
