Configure CocoaPods properly

[alexsegura]

We are using CocoaPods because some libraries (like react-native-maps & tipsi-stripe) need it.
But, it is complicated because React Native doesn't support it really well.

From what I understand, the problem is that when using CocoaPods, some libraries are included twice. Because there is code which is included via the Pods project AND via the main project.

This is explained in cocoapods-fix-react-native

The code below in ios/Podfileshould fix the problem, this is explained on react-native-maps documentation

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end
