Main Thread Checker: UI API called on a background thread: -[UIView init]

Describe the bug
Calling Analytics.init() crashes my app with the following error:

Main Thread Checker: UI API called on a background thread: -[UIView init]

The line causing the crash is this in AppleUtils.swifts userAgent computed property:

return WKWebView().value(forKey: "userAgent") as? String

To Reproduce
Steps to reproduce the behavior:

1. Call the initializer of Analytics from a background thread (e.g. utility)

Expected behavior
Analytics is a task that I expect to work in the background.
