Xcode warnings in two swift files

[ingopaulsen]

Describe the bug
I have received the following warnings in Xcode for SwiftMessages package (the numbers in brackets indicate the frequency):

BaseView.swift:

(2) Non-'@objc' instance method in extensions cannot be overridden; use 'public' instead

SwiftMessagesSegue.swift:

(1) Unnecessary check for 'iOS'; enclosing scope ensures guard will always be true

Environment (please complete the following information):

• Xcode version: Xcode 15.0
• SwiftMessages Versions: v9.0.6, v9.0.9
• Device: iPhone7
• Simulator: iPhone15
• OS: iOS 15+

Thanks for calling my attention to this.

I wasn't able to reproduce the warnings, but I made some guesses and I think it should be good now. Could you pull down the head of master and let me know if the warnings are cleared up?
