Flutter iOS build fails with "Framework 'Pods_Runner' not found" on Xcode 26.2 beta

I'm getting a linker error when building my Flutter iOS app on the simulator:

Error (Xcode): Framework 'Pods_Runner' not found Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

Environment:

Xcode 26.2 (Build 17C52)

macOS Darwin 25.2.0 (Apple Silicon M1)

Flutter (stable channel)

CocoaPods

What I've tried (none worked):

flutter clean + flutter pub get + pod install

pod deintegrate + pod cache clean --all + pod install

Clearing DerivedData (rm -rf ~/Library/Developer/Xcode/DerivedData)

Changing use_frameworks! to use_frameworks! :linkage => :static in Podfile

Adding FRAMEWORK_SEARCH_PATHS with ${PODS_CONFIGURATION_BUILD_DIR} in post_install

Completely deleting the ios/ folder and regenerating it with flutter create --platforms ios . — same error on a fresh iOS project

Key finding: The Pods_Runner.framework is never produced in the build output. The Pods-Runner target exists in Pods.xcodeproj with productType = "com.apple.product-type.framework", and the main Runner.xcodeproj references Pods_Runner.framework in its link phase, but Xcode 26 never actually builds it.

Podfile:

platform :ios, '14.0' ENV['COCOAPODS_DISABLE_STATS'] = 'true' project 'Runner', { 'Debug' => :debug, 'Profile' => :release, 'Release' => :release, } # ... flutter_root helper ... target 'Runner' do use_frameworks! flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__)) target 'RunnerTests' do inherit! :search_paths end end post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) end end

Dependencies include: flutter_secure_storage, google_mlkit_face_detection, mobile_scanner, image_picker, shared_preferences, sqflite, path_provider

This seems to be an Xcode 26 beta issue since a completely regenerated iOS project fails the same way. Has anyone found a workaround?
