I'm updating my apps to iOS 9 using Xcode 7.1. I upgraded the watch apps to OS 2 like chaning openParentApplication to use WCSession. When submitting, I get this warning in an email:
"WatchKit 1.0 - Your previous version used an extension for Apple Watch but your current version doesn’t. Users who haven’t updated their Apple Watch to watchOS 2 or later may lose access to their Apple Watch extension."
How can I support both the watchOS 1 and watchOS 2? Xocde doesn't even let me choose OS1 as a base SDK.
