fix: Disable view controller methods swizzling when Xcode is running for previews

[kzyryanov]

Description

SwiftUI previews the normal setup for UIKit doesn't happen, so the Objective-C method swizzling in RNScreens causes an infinite loop because findChildRNSScreensViewController , which is called by reactNativeScreensChildViewControllerForStatusBarHidden (and other swizzled methods), always returns nil.

This fix disables swizzling when Xcode is running for previews.

This may bring some issues if RN screens are within SwiftUI navigation stack but at least for basic SwiftUI previews that fix works.

Fixes #1602

Hey! Thanks!

I'm reluctant to merge this PR atm, since my first impression is that potentially correct behaviour at application runtime is more important than preview.

I don't have any other insights though. Will need to test, whether there are some issue caused for real or not.
