Deprecation Warning for AppAuth - swift

Question

I got some warning message. Most of them disappeared after updating related Pods. But these 3 warnings are still there. I don't have the AppAuth pod but the Firebase/Auth and Firebase/Core. What should I do to get rid of them?
Thanks,
Below is the Podfile.
=========================
# Uncomment the next line to define a global platform for your project
platform :ios, '10.0'
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
end
end
end
target ‘test’ do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# use_modular_headers!
# Pods for test
pod 'Firebase'
pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'GoogleSignIn'
pod 'Firebase/Firestore'
pod 'Firebase/Storage'
pod 'Firebase/Crashlytics'
pod 'Firebase/Analytics'
pod 'Firebase/DynamicLinks'
pod 'Firebase/Performance'
pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'
target ‘testTests' do
inherit! :search_paths
# Pods for testing
end
target ‘testUITests' do
inherit! :search_paths
# Pods for testing
end
end

AppAuth is a dependency of GoogleSignIn that is designed to work on iOS 7 and above.
Changing the version to 10 in the post_install script in the Podfile by deleting the minimum iOS version 7 causes the warning.
Instead of deleting it, you might be able to eliminate the warning and also the Xcode 12 warning because of no iOS 8 support by changing the minimum version to 9:
post_install do |pi|
pi.pods_project.targets.each do |t|
t.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
end
end
end
Thanks to https://stackoverflow.com/a/58367269/556617 for the post_install script.

As indicated Xcode, it was deprecated so use this new method instead of openUrl
open func open(_ url: URL, options: [String : Any] = [:],
completionHandler completion: (#escaping (Bool) -> Swift.Void)? = nil)
If you realize two new parameters has default values: an empty dictionary and optional closure which is nil. That is why you can easily use as openUrl
