Could not build the application for the simulator.
Error launching application on iPhone 11.

and i have done everything from flutter pub get, done pod install, pod update, flutter clean and flutter run but the error is coming and i have latest versions of flutter, dart, cocoapods

Answer 1

Go to Podfile which is in the iOS directory and change the ios version

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0' // you have to change this because firebase required 9 to 14

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
