Make APNSEnvironment public

[joshuapoq]

With version 19 we have no access to .validate() using the 'current' environment if it can be determined.

Looking into the code you have an APNSEnvironment struct that has public static func isProduction() functions that would bridge this gap.

The main struct is not public so these are not accessible; please could that be changed?

Yep we can expose that struct. The validate is just checking the credentials. If you are setting both I would just validate both types each time.

This is going to be bundled with 19.1.0, hopefully next week. For now you can just copy the struct to your app so you are not blocked
