I’m on a MacBook Air 2025 M4 (Apple Silicon) using Flutter 3.35.5 on channel stable, Xcode 26.0.1, and CocoaPods 1.16.2.
Actual Setup:
| Component | Version |
|---|---|
| macOS | 15.0 Sequoia |
| CPU | Apple M4 (ARM64) |
| Flutter | 3.35.5 on channel stable |
| Dart | 3.9.2 |
| DevTools | 2.48.0 |
| CocoaPods | 1.16.2 |
| Xcode | 26.0.1 Build 17A400 |
Since updating Flutter from 3.24 → 3.35, iOS builds consistently fail with the following errors (not matter if simulation or real device, also ios version no matter):
fatal error: 'Flutter/Flutter.h' file not found

What I’ve verified
flutter clean + flutter pub getpod install --repo-updateDeleted DerivedDataVerified Generated.xcconfig existsVerified FLUTTER_ROOT path is correctTried both in Podfile use_frameworks! :linkage => :static and modular headersTried flutter build ios --no-codesign
Still, the same errors appear.
Observations
- I couldn’t find a solution with ChatGPT or searching in the Internet like on Stackoverflow
- Since Flutter 3.35, Flutter.framework is no longer under
.../engine/ios/Flutter.framework, but instead part of.../engine/ios/Flutter.xcframework/ios-arm64/Flutter.framework - After
pod install, there is no Pods/Flutter/Flutter.xcframework folder at all. - Running
flutter build iosdoes not generate the framework either — Flutter seems to depend on dynamic build-time injection, but the plugins expect static headers at build time. - On my Windows machine, the exact same project and plugin versions build perfectly (obviously without actual iOS compilation).
