UIApplication.shared.windows deprecated in iOS 15

[dmeehan1968]

The following line throws a deprecation warning in iOS 15.

episode-code-samples/0086-swiftui-snapshot-testing/PrimeTime/CounterTests/CounterTests.swift

Line 13 in 2f1621f

let window = UIApplication.shared.windows.first!

This can be updated to:

guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
      let window = windowScene.windows.first
      else { return }

Hi @dmeehan1968! Episode code samples are a bit "frozen in time" for now. You should always be able to open them up in the version of Xcode that was available at the time, though! Hopefully most code samples can be modernized with just a little work, though 😄

I'm going to convert this to a discussion, since we don't intend to update old code samples at this time, but thanks for taking the time to chat about it!
