Problem with running IOS simulator for my flutter app - ios

Question

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
/Users/MyUserName/Desktop/my_app/build/ios/iphonesimulator/Runner.app on
82562E3A-E7BD-4FE0-9BF9-8BB9C7AD5F15. This is sometimes caused by a malformed
plist file:
ProcessException: Process exited abnormally:

(domain=IXUserPresentableErrorDomain, code=1):

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?

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

Save time, just go to erase device content and settings from the emulator, then run flutter clean. App should run fine then.

Answer 5

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.

Answer 6

This happens if the GoogleService-Info.plist is missing.

Answer 7

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.

Answer 8

An alternate solution is to run the Runner.xcworkspace app once from Xcode and this may fix it.

Answer 9

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.

Answer 10

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.

Answer 11

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

Answer 12

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!
