I am having this issue where I the application isn't building because it says
fatal error: 'Flutter/Flutter.h'
file not found
#import <Flutter/Flutter.h>
I've been working on this issue the whole day, but haven't gotten anywhere. It's a simple program (the initial code that you get when you open flutter new project), and have added firebase_core.
Whole XCode output:
Xcode's output:

My Flutter was working fine until a month or two ago. Flutter version = 2.0.6
Any help is greatly appreciated.
Thanks
I managed to fix it by following these steps:
1. Open your terminal in root level of your project.
2. run flutter upgrade.
3. Change SDK version in pubspec.yaml file
4. In my pubspec.yaml I just changed This line sdk: “>=2.7.0 <3.0.0” and replaced with sdk: “>=2.12.0 <3.0.0”
5. flutter clean
6. flutter run.

I added firebase_crashlytics to my Flutter project and followed the Firebase guideline in order to install it.
On flutter run the app works well without any error.
ONLY DURING flutter build ipa I get this:
Error (Xcode): 'Flutter/Flutter.h' file not found
/project/ios/Runner/GeneratedPluginRegistrant.h:9:8
Error (Xcode): failed to emit precompiled header
'/Users/macnew/Library/Developer/Xcode/DerivedData/Runner-biyumwxiyqxyjkacscuqcbwbjroj/Build/Intermediates.no
index/ArchiveIntermediates/Runner/PrecompiledHeaders/Runner-Bridging-Header-swift_26UGEQJVHLD5H-clang_19ZWN9O
PIOOJI.pch' for bridging header '/project/ios/Runner/Runner-Bridging-Header.h'
Encountered error while archiving for device.
Any advice about this?
I'm using firebase_crashlytics 2.8.6 (latest version) and flutter 2.10.5 (without null-safety).
Since I tried every solution given on StackOverflow and Github (Flutter repo), here you have the solution:
Delete the "ios" folder
Run the app and create the iOS project
Inside the "ios" folder ("cd ios"), run the command "pod install"
Follow the official guide by the iOS side
This is the only solution that works.
well this error occurs to me when I try to make my app in production.
The app is created with flutter and I was able to create the apk for android, but when I try to do it for ios it won't let me.
The file that I am opening is Runner.xcworkspace and the problem is the import of a flutter library, it seems to me that I have to make some kind of connection with the pods.
here is the error, I want to tell you that I do not want to run the app, but to make an installer
The error that occurs when building a release (ie. flutter build ipa) and not when running a debug build is:
/[REDACTED]/ios/Runner/GeneratedPluginRegistrant.m:48:9: fatal error: module
'flutter_secure_storage' not found
#import flutter_secure_storage;
~~~~~~~^~~~~~~~~~~~~~~~~~~~~~

note: Using new build system
For me regenerating Podfile in the following way solved the issue:
rm ios/Podfile && flutter build ios
See Closed [ios][release] GeneratedPluginRegistrant.m Module not found
#43986
I have several problems after updating to flutter 2 someone can help me solve them, I list the log below
Flutter console error:

(0x1f9b08188) and ?? (0x113d382b8). One of the two will be used. Which one is undefined.

I had the same issue. I saw the same error when I ran flutter build ios.
The error message was displayed red color on my VS code terminal, but it was kind of misleading. I found it was not the main issue.
The actual issue should be on the following error section.
So, please run flutter build ios --verbose and read the output carefully.
In my situation, there were other issues of the failure of flutter build ios. The issues were like forget to put in GoogleService-Info.plist or iOS target version is less than the requirement of flutter packages.
When running the project on a simulator everything seems to work fine. Once i tried to deploy to an actual device I get the following error:
iOS Version - 13.0
Xcode Version - 11.3.1
Flutter Version - 1.12.13+hotfix.8

Make sure you have added flutter we bauth dependency plugin in your pubspec.yaml
dependencies:
flutter_web_auth: ^0.1.3
If it's added and it still does not works, ensure also that the pod install works fine to add the plugin.
I'm getting a build error using the flutter speech_recognition package. Try to build for iOS right now. Haven't tested Android.
I followed the installation guide. The package seem to load after modifying the .yaml file. I'm using the Visual Studio IDE on a MacBook Pro.

Any help would be appreciated!!
Make sure that the project has been created with the -i command as shown below: futter create -i swift [your_project_name].
after doing this verify that you are using in the properties of the runner SWIFT_VERSION = 4.2. since previous versions could cause this error.
And finally add below in podfile:
target 'Runner' do
use_frameworks!
