Flutter Run - lost connection to device (Simulator iPhone 11 Pro Max)

everytime I intend run a project on the IOS simulator I have a message "Lost connection to device". It previously worked fine, i don't remember exactly to interfere in some way with Xcode or something. Everything OK on flutter doctor though...

The report I receive is:

The problem for me was a permission error when the app was trying to access user geolocation but in order to first see that error (Android Studio was not helping), I needed to connect my physical iPhone to my laptop using a cable and try to deploy the app there directly from Xcode.

Then after seeing the error on Xcode. Inside the Info.plist file, I add these two lines lo fix it:

<key>NSLocationWhenInUseUsageDescription</key>
<string>This application requires location services to properly work</string>

<key>NSLocationAlwaysUsageDescription</key>
<string>This application requires location services to properly work</string>

Then, the app was successfully deployed in the emulator and my real device.
