I have a flutter app i have developed and it is running efficiently on a real device with zero errors or warnings in debug mode. however when i deploy a release to the same real device it produces a white screen on most pages. I am producing the release using X-code. What could be the problem?
connect your device using cable.
then write following command in terminal.
flutter run
to see error log in terminal in red colors.
Open Terminal and Go to /ios folder inside your project.
Executes pod deintegrate command.
Then after pod install
Run your project Flutter run

I am running a flutter app on the Android simulator successfully but when I run it on the iOS simulator the app opens to a white screen then crashes.
I have done all of the following about 10 times each.
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
sudo xcodebuild -runFirstLaunch
sudo xcodebuild -license
flutter update
flutter clean
xcode clean build folder
flutter build ios
flutter run
Remove the Pods folder and Podfile.lock files.
cd ios
pod deintegrate
cd ..
flutter clean
flutter build ios
Xcode 12.5.1
I also made sure Xcode Signing & Capabilities were set. I also stopped and removed all antivirus software.
It doesn't work by running debug and running via terminal ( flutter run --enable-software-rendering ) doesn't show any errors.
UPDATE:
Deleted the iOS folder and tried to run flutter create and now getting.
"No option specified for the output directory"
flutter create doesn't work.
Got the above flutter create working and now the app won't install on the Android device at all, where as it was working before flutter create was run (suggested below). Added memory and wiped Android simulator and still won't install on Android saying not enough memory. Deleting the ios folder and running "flutter create" was a disaster.
Rolling back to original code. Still stuck on not installing on iOS. It has to be something with Xcode.
Just make a new React Native projects on new Macbook M1. At first it was building on Xcode 12.4 with any troubles. But after a few days build failed with error:
fatal error: module map file '/Users/jocoders/Library/Developer/Xcode/DerivedData/CryptoWalletApp-hfiwvoyqlbgufkgtyvqtxygiaodf/Build/Products/Debug-iphonesimulator/YogaKit/YogaKit.modulemap' not found
What I already tried, but nothing works from it:
Checked cocoapods build target and it is the same version as my projects build target https://github.com/facebook/react-native/issues/28503#issuecomment-643744117
Rebuild a project;
Install pod with command arch -x86_64 pod install;
Put arm64 in Xcode Excluded Architectures https://github.com/facebook/react-native/issues/28503#issuecomment-770378485.
Guys can you tell me please how to solve it? Is it possible now to develop for React Native on new Macbook M1? I have it already a few weeks, but still not work on IOS, because it is so painy, a lot of errors. And I was waiting more surprises from Android more then IOS, but in real Android works with out any troubles.
All day I tried to find the decision and nothing worked to me except it: please try to open Xcode through Rosetta - Right click on Xcode in applications folder -> Get Info -> set Open with Rosetta to true
When you try to create a project using the below command in M1(Apple Silicon Chip):
npx react-native init ProjectName
Try to build using below steps:
Open Terminal and install rosetta
Type "softwareupdate — install-rosetta" command in your terminal.
After installation completes, go to the Application.
Find Terminal App
Right click and make a Duplicate Terminal
Now right click on a duplicate terminal and click on "Get Info"
You will see checkbox with option "Open with Rosetta". Enable it. Rosetta checkbox in terminal
That's it. Rename your rosetta terminal so that you can identify it easily.
Open your Rosetta Terminal and run the command npx react-native init ProjectName
After project initialisation done type npx react-native start to start metro.
Now type command npx react-native run-android for run into Android
Type command npx react-native run-ios for run into iOS.
After project initialisation is done you can run start and run command in VS Code also.
I had this problem with react-native 0.70 and xcode 14.2, and i was able to eventually get the app to run by opening the .workspace (NOT the .project xcode file) xcode file in xcode and running (the "play" button in xcode) from the root directory.
After this worked (the app succesfully ran in the ios simulator), i was able to run metro in the terminal and then run
yarn react-native run-ios
from within the ios folder of the app.
The app succesfully built and ran from terminal.
I had the same issue although not on a M1. I fixed it using all the recommendations from this answer.
Quoting the answer there for reference:
Make sure your cocoapods build target is the same version as your
projects build target.
Try rebooting your machine.
Examine your podfile to make sure your build scheme is included in it.
The last thing that really helped me was rebooting the machine. Strange!
I have got an M1 mac setup. The above methodologies were not working for me. However, this worked: Run XCode Rosetta
Finder -> Xcode in applications folder -> Get Info -> set Open with
Rosetta to true
Xcode is now under Rosetta.
I'm trying to build my Flutter app for iOS using xCode and got error:
.../ios/Runner/GeneratedPluginRegistrant.m:10:9: Module 'sqflite' not found
When I'm trying to build application with flutter with command
flutter build ios
I don't have any problem. Application build successfully.
I tried to delete Pod directory in ios folder and then install pods from scratch
flutter pub get
pod install
How to fix this problem with xCode?
XCode gives this type of Error like Module 'something' not found, when sometimes the problem is somewhere else.
So, what I did is after running flutter build ios command, I didn't try to run it in XCode. Because it was giving these errors.
So, I archived the app and tried to publish in App Store Connect. Then I found the real issue/bug on my code.
App store doesn't support transparent logo or app icon. This was the bug in my case.
So you can try to archive and publish to app store connect. It may show you the real reason.
Change your target Destination to > Any iOS Device
This work for me
"I found the solution,
In the existing project, once you guys add sqflite dependencies
Profile file in IOS folder will not generate code
we need to remove Podfile in ios
rm ios/Podfile
and run the project again, it works for me."

I haven't touched my Ionic projects in around 1-2 months.
All my projects were running perfectly then.
I go to try run them today and every single one of them is saying
Showing Recent Messages
/Users/jakelewis/Desktop/fifteen-project-e/ios/App/Pods/Target Support
Files/Pods-App/Pods-App.debug.xcconfig: unable to open file (in target "App" in project "App")
They were all running perfectly. I haven't updated Xcode yet to the latest because it's still in the process of downloading. What would cause this issue?
It's a nightmare.
Somethings I tried, removing the ios folder and npx cap add ios
Even went on GitHub and went to rollback versions I knew that ran perfectly on IOS before.
I am using capacitor on most of my projects.
This did not fix the issue.
close XCode
run ionic capacitor copy ios to build it.
run pod reintegrate and pod install (navigate to where the pod file is located first, ex: cd ios/App and then run "pod install" command)
open XCode again use ionic capacitor open ios command
This work for me
try this:
Close XCode
open a terminal, go to the project and execute
pod install inside your app folder (where Podfile is located)
My iOS emulator is no longer opening when I run "phonegap run ios" in the terminal on Mac OS X. I receive no error messages and:
[phonegap] Platform "ios" deployed to emulator.
[phonegap] successfully installed onto emulator
While this is currently a known bug, you can run the emulate command more directly (note you need to build separately):
phonegap local build ios
/platforms/ios/cordova/emulate
You can also run the application using the same technique:
phonegap local build ios
/platforms/ios/cordova/run
NOTE: When using this method to run the app on your phone, the task might get stuck on the splash screen. To fix this, launch the Activity Monitor on your Mac and quit any processes with the name "ios-deploy". From there you can launch the application on your phone by clicking the application icon.
Or, you can even look inside the generated /platforms/ios folder and launch XCode project directly to test in an emulator or on your device. Open project and click the RUN button.
IMPORTANT: with all of the above methods, you MUST run the build command before running:
phonegap local build ios
Not really an answer, but I can say this is a known bug. Here is the bug so you can track it:
https://issues.apache.org/jira/browse/CB-5103
I only had this problem after upgrading to 3.1. I downgraded to 3.0 and it works more reliably:
npm uninstall -g phonegap
npm install -g phonegap#3.0
Also had to delete the platform/ios dir and plugins/ios.json and then run 'phonegap build ios' and 'phonegap run ios'
