I'm trying to run my flutter app on the IOS simulator and its not working. So tried on the most basic flutter app (create my_app and then tried to run it) and nothing seem to work!
Everything seems to work fine when I run it from the terminal until the linking and signing phase and that where I get the error, how can I fix it?
This is the error I get:
Unable to install

82562E3A-E7BD-4FE0-9BF9-8BB9C7AD5F15. This is sometimes caused by a malformed
plist file:

Edit:
I updated my MacOS, Deeleted and reinstalled Xcode, I even tried to run the most simple swift app and I get always this same error, it looks like the build was successful but it unable to install. I still get this same error, what can I do?
This occurred when I opened the Simulator first and then updated XCode -- even without running the app until after XCode updated completely.
What worked for me:
Close Simulator completely (from the dock, right-click -> "Quit")
Close XCode (if applicable)
Run flutter clean
Re-open Simulator
Re-open XCode and let it compile
Run the app again
If it still does not work, try resetting the device at "Device" -> "Erase All Content and Settings..." from the Simulator menu.
I had the same issue a couple of days ago
What I did - and what fixed the problem - was to reset the simulator (Device -> Erase All Content and Settings), and then run $ flutter clean
You should now be able to run your app again
None of the above worked for me. I created another flutter application and copied it's ios folder to my project. Worked like a charm
Save time, just go to erase device content and settings from the emulator, then run flutter clean. App should run fine then.
Run flutter clean and then run your app again
If error persist, generate a new flutter project on Android studio. Replace the ${projectHome}/ios/Runner.xcodeproj folder with the ${newFlutterProjectHome}/iOS/Runner.xcodeproj. Your app should run fine now.
If error persist still, delete the ios folder and replace it with a new one copied from a freshly generated project.
This happens if the GoogleService-Info.plist is missing.
This also happens when you have updated your XCode and your simulator is in the background.
Close the simulator and open the Xcode, you will get an option to install additional tools, install them and then run the application.
An alternate solution is to run the Runner.xcworkspace app once from Xcode and this may fix it.
In my case it was because of hanging empty GoogleService-Info.plist file inside Xcode after migrating to new Firebase (FlutterFire) initialization.
Xcode is not a regular drag and drop IDE which directly maps project files to the ones in the file system. It rather caches file references. So even when you delete a .plist file, the Xcode still maintains a reference to it.
Simply opened Xcode IDE and removed .plist file (which updated project.pbxproj in turn). This helped me to compile the project fine.
I had this same issue recently. I found out I added my GoogleService-info.plist file to the subdirectory Runner and not the main Project directory Runner through xcode. I opened up xcode again, deleted the file and re-added it to the proper place and now everything is working correctly.
for this you have to give some value in CfBundleVersionShortString like
<key>CFBundleShortVersionString</key>
<string>1.0</string>
And Give the build value in Runner as 1.0 and version as 1.0
enter image description here
To be honest. it's really frustrating for the developers
This is how I fixed!
flutter clean
flutter pub get
go to ios folder
rm Podfile.lock
pod repo update
pod install
Then it works!
yesterday I was working fine with Flutter, now i'm facing this issue and I already search everywhere for a solution but no success.
When I run:
flutter run
The build process starts and when its about to finish the error below is shown:
Launching lib/main.dart on iPhone 11 Pro Max in debug mode...
Xcode build done. 12.3s
Failed to build iOS app

Exited (sigterm)
Looks like the process is trying to open this file Session.modulevalidation for writing, but this file really does not exist in that folder. And I don't know what to do.
Things that I already tried:
Reinstalling xcode
flutter clean
Clone my project again in another folder and try to build, but same error
Created a new flutter dummy project and tried to build, still same error
Rebooting machine several times
Give permissions to Staff to the DerivedData and ModuleCache.noindex folders
Deleted the DerivedData within hope that xcode build will recreate all the files needed, but, it created everything again but not that particular file.
So that's it, If any blessed human know how to 'recreate', or reset, clear some cache, I would be very thankful.
Before running your project, check everything is checked when running:
flutter doctor
and also make sure at least a device is connected or open iOS simulator first. You can check if flutter is successfully connected to the device by:
flutter devices
when you make sure that flutter detect your device or the simulator, then run your application by:
flutter run
After hours I finally found the solution as it follows:
Without any hope I opened my flutter project with Xcode, and then tried to build the Runner target from there, same error.
Then, I was browsing the Xcode preferences and something caught my attention, on Locations section I found something about DerivedData location, it was set as Default. So, I changed from Default to Custom location and I set to a new folder on my home directory:
Then immediately Xcode created the entire DerivedData/ModuleCache.noindex folder and with them, the Session.modulevalidation file as well.
Then I closed Xcode and tried flutter run again, and it was successfully build!
I'll let this answer to those who may come here for help.
Building our Flutter project fails on iOS. The following steps work without problems:
running on the XCode simulator (flutter run)
building in the terminal (flutter build ios)
running on a real device in debug mode (flutter run -d "abcd")
If I open the project in XCode, change the build target to "Generic iOS Device" and hit "Build" or "Archive" I get the following error:
/Users/.../development/testproject/ios/Runner/GeneratedPluginRegistrant.m:6:9: 'flutter_exif_rotation/FlutterExifRotationPlugin.h' file not found
After removing the FlutterExifRotationPlugin, the error reoccurs with the next plugin alphabetically, so I figured that plugins in general don't work at the moment.
I tried:
dev, stable and master channels of flutter
reinstalling XCode
reinstalling Flutter
create a new project and moving the old files there
But nothing worked so far.
Ok the solution was very simple. I had to open the .xcworkspace file instead of the .xcodeproject one.
One WEEK went down the pipe for this error. I hope that you, future reader, will find this comment useful.
I'm working on a basic app and every time I try to run the project I get this warning:
Failed to launch IBCocoaTouchImageCatalogTool via CoreSimulator spawn
I've tried everything I could find on the internet but no one has been able to find the right answer for me.
I've tried cleaning the project.
Removing the assets folder, cleaning the project, then adding the
assets folder again and trying to build.
I've tried to clean the project, restart XCode, then run the app.
I'm all out of ideas on what to do and I can't seem to find an answer anywhere.
Thank you in advance for any ideas you might have!!

Seems to be an issue if you're using Xcode 10 and < 10.14 Mojave beta.
Is there a way to download this /PrivateFrameworks folder back? It seems like this has the framework to make simulator work. I have re-downloaded xcode9 and it does not come back. Also tried re-installing xcode command line tools but this PrivateFrameworks doesnt seem to be part of the Xcode bundle nor the Command Line Tools bundle. Idea's Anyone?
There's no need to get a copy from a friend. The contents of PrivateFrameworks come inside an installer package provided with Xcode starting from version 9. You should have this file as part of your Xcode install, even if you just downloaded Xcode from the App Store.
Just run in your Terminal:
open /Applications/Xcode.app/Contents/Resources/Packages/XcodeSystemResources.pkg
And your PrivateFrameworks folder will magically be back. 🙂
