All my side I can yarn ios success.

If you still failed please try these steps below

• delete Podfile.lock
• yarn
• cd iOS & pod install
• yarn iOS

I believe we don't need to install ios-deploy to run the command, as my previous projects haven't required it. Additionally, the weekly download rate of ios-deploy is not high enough to warrant its installation.

@baonguyenhsts after uninstalled ios-deploy my side, It still working when run yarn ios. Could you check it again? Thank you

I encountered this issue after running my app on both actual physical device and simulator. So I go to Xcode > Device and simulator > unpair real device. And then it's working
