[@nativescript/firebase-firestore]

Reproduce the iOS build from the package.json dependencies and the App_Resources/ios Podfile and build.xcconfig settings. Start with the CocoaPods deployment-target error, then inspect the linker output for the Firestore, nanopb, and Swift symbols. Done means a plain NativeScript Angular project builds successfully with @nativescript/firebase-firestore.

I am trying to use the offical native sript firebase and firesore plugins.

I created a plain nativescript angular project and installed

npm install @nativescript/firebase-core 
npm install @nativescript/firebase-firestore

I got this error message :

Pre-downloading: `FirebaseFirestore` from `https://github.com/invertase/firestore-ios-sdk-frameworks.git`, tag `9.6.0`
[!] CocoaPods could not find compatible versions for pod "FirebaseFirestore":
  In Podfile:
    FirebaseFirestore (from `https://github.com/invertase/firestore-ios-sdk-frameworks.git`, tag `9.6.0`)

Specs satisfying the `FirebaseFirestore (from `https://github.com/invertase/firestore-ios-sdk-frameworks.git`, tag `9.6.0`)` dependency were found, but they required a higher minimum deployment target.

As recommened i added podfile and build.xcconig in App_Resources/ios

IPHONEOS_DEPLOYMENT_TARGET = 11.0;

platform :ios, '11.0'

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
    end
  end
end

this leads to other errors :

Maybe there are some issues with nanopb.
