PostHog causes accent color in SwiftUI app to be reset

[terabyte128]

Version

3.14.1

Steps to Reproduce

1. Initialize PostHog in a SwiftUI iOS app, like this:

let config = PostHogConfig(apiKey: POSTHOG_API_KEY, host: POSTHOG_HOST)
config.captureScreenViews = false
config.sessionReplay = true
config.sessionReplayConfig.screenshotMode = true
config.sessionReplayConfig.maskAllTextInputs = false
config.sessionReplayConfig.maskAllImages = false
PostHogSDK.shared.setup(config)

2. Run the app

Expected Result

The accent color defined in the app's assets is respected.

Actual Result

It is not.

I believe this is a regression of of #54. It seems that when the library was re-written in Swift, it began using the deprecated UIScreen.main symbol again. Applying the following diff appears to fix it:
