Problem with running IOS simulator for my flutter app

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:

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?

Solution 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:

1. Close Simulator completely (from the dock, right-click -> "Quit")
2. Close XCode (if applicable)
3. Run flutter clean
4. Re-open Simulator
5. Re-open XCode and let it compile
6. 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.

Solution 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

Solution 3

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

Solution 4

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
