React-native-navigation: iOS 13 critical issues

[exentrich]

Issue Description

Apps build with Xcode 11 now forces new behavior introduced in iOS 13:

• Swipe down to dismiss for modals
• Increased height of topBar for modals
• Dark mode

Unfortunately RNN do not support any of this changes properly. And it's deal-breaker for all developers. Now we can't deploy latest update for our apps, due to several issues (sorted by severity):

1. When modal is dismissed with swipe, screen is not unmounted properly and memory not released. This makes memory leaks. componentDidUnmount not works https://github.com/wix/react-native-navigation/issues/5370
2. Swipe back doesn't work
3. TopBar Title misaligned in modals https://github.com/wix/react-native-navigation/issues/5564 https://github.com/wix/react-native-navigation/issues/5431
4. When dark mode is on, status bar become transparent (nothing is visible, white text on white background)

This issues easily reproducible in Playground app.

I made this ticket to gather all problems we have in iOS 13, because the main reason for all of the problems is latest iOS update. So I think we could close all other separate tickets and keep discussion here.

Here pull-requests that possibly fix part of the problems:

Regarding the dark mode, you can disable it by adding this into the app info plist

<key>UIUserInterfaceStyle</key>
<string>Light</string>

In our apps, the header doesn't have any titles and the back button doesn't appear... Is this related to this issue ? (on iOS 13 only)

No, I have back and the title showing, iOS 13, xcode 11.

For me, swipe back works fine on a real device, but not an emulator. But enabling device bezels solves an issue.
