Swift template is using Swift 4 #40400
Description
A significant part of the argument for switching the default iOS template to Swift was that with Swift 5, newer iOS devices wouldn't have the size overhead of having all the Swift libraries bundled in an app.
However, our Swift template is currently using Swift version 4, which means that's actually not the case unless developers go in and manually change their project settings. Lots of people are going to have unnecessarily large new apps under the current settings.
We should make the language default for the app and plugin templates 5, not 4. This will require:
- Actually changing the value in the Xcode project templates
- Updating the Swift code in the templates to use Swift 5
- Making Xcode 10.3 the minimum supported version in flutter_tool (currently its 9)

Since we shipped Swift-by-default to stable, should we consider a hotfix for this?

Off the top of my head, this would involve:

I thought we didn't use Swift in first-party plugins yet, because it would have caused the size bloat for everyone using them.

You're right. Maybe check the top 50 plugins? I doubt there are more than a handful if any. #25676
