I upgraded to fluter 2.5 from 2.2.3. Then I returned it back to version 2.2.3. After that, I cannot start debugging mod on a real ios phone, stuck on Installing and launching. Removing the fluter cache and clearing the fluter does not help.

Didn't help, after flutter run --release. I try to launch debug mode, but I receive the same Error( And I can't find this settings in my phone phone-> general->device management->trust the apple id.
First you have to delete pod, podfile.lock, .symlinks folder along with pod file then do flutter clean and uninstall the app, if already install in your phone then do flutter run --release and if still the problem persist then open XCode signing the application then try again. hope that will solve the problem.

the flow goes like this:

  1. plug your device using data cable to you MAC run xcode-> select you phone on the top-> (note if the version of your iPhone's OS is not recognized then update xcode to 13.1) you can find several videos on that.
  2. then hit the play button from xcode after some time it will ask a key-chain password-> give your MAC's password.
  3. then at the end you've to add trust in your phone. simply go to setting in you phone-> general->device management->trush the apple id.
  4. you are good to go!
