Xcode crashes when trying to make a UI test that involves a webview

Question

Working on building an automatic UI test for a swift iOS app. The app involves a web-view for logging in with facebook. Every time tap within the bounds of the web-view and try to log into facebook it crashes Xcode if I am attempting to build the UI test using the built in Xcode UI recording. It does not matter if I use my iPhone 6 or a simulator, no matter what Xcode will crash.

I am using Xcode 9. And the FBSDKLoginKit and FBSDKCoreKit.

Steps to reproduce:

1) Have an app with a webview

2) Hit record UI test

3) Click anywhere within the bounds of the webview

Is there a reason for this behavior?

Are there settings in Xcode I need to change in order to record web-view interactions?

Below is the error message I get when Xcode crashes.

This seems like an Xcode bug to me. You can report it on the Apple Bug Reporter.
