XCUIApplication is only available on iOS 9.0 or newer, swift3

Question

This app worked great, I published and updated this app multiple times. I just migrated over to swift 3 from swift2.2 and now I get the following error:

XCUIApplication is only available on iOS 9.0 or newer

My iOS Deployment Target in Info is 9.0 (see image below) so I'm not sure what is causing this. Note, I can build and run the app in simulator mode and on a physical device (I tried running on iPhone 6 & 6+ and it works fine). I am concerned going forward without addressing this issue. Any help/suggestions would be greatly appreciated.

Here is a screen grab (below) from *UITests.swift in Xcode of the line associated with this error (XCUIApplication is only available on iOS 9.0 or newer).
