无法在 iOS 仿真器或物理设备上构建 Flutter 应用程序 - 虽然在 Android 上工作正常

Question

I've returned to Android Studio & Flutter after some time away and I've tried to build my app and I get the following error:

Launching lib/main.dart on iPhone 11 Pro Max in debug mode...

[!] Automatically assigning platform `iOS` with version `8.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Answer 1

Replace your whole pod file with the text below.

# Uncomment the next line to define a global platform for your project

# platform :ios, '9.0'

target 'testing_gowtham' do

use_frameworks!


pod 'Firebase/Core'
pod 'Firebase/Firestore'
end

If solution 1 is not working then you can also try the solution 2

platform:ios, '9.0' is working...I simply removed # this
