Thank you Trevor! Adding this to my info.plist opted out of Dark Mode:
<key>UIUserInterfaceStyle</key>
<string>Light</string>
Apple's ominous note at the end of that article gives me the
impression that before too long (iOS 14?) this override will get the
app rejected:
"Supporting Dark Mode is strongly encouraged. Use the
UIUserInterfaceStyle key to opt out only temporarily while you work on
improvements to your app's Dark Mode support."

Is there a way to determine if an iOS device has dark mode ("Dark
Appearance") enabled from within a LiveCode app?
The inherited default text color of a field is black, but is changed
to white by the OS when this mode is enabled (on a white background in
this case which makes it appear invisible). This seems to only affect
native mobile text fields, but not LC text fields.
There is a feature enhancement to support dark mode for macOS, but I
didn't see any reports for iOS.

I'm not asking for an engine change, just curious if there is a way to
check this so I can code around it. Perhaps mergNotify?
I don't know of a way to check this from within LiveCode using existing
tools. There is an API for checking which is documented here:
https://developer.apple.com/documentation/uikit/uitraitcollection/1651063-userinterfacestyle?language=objc
It should be possible to wrap that API using LiveCode Builder. From what
I've read, I think you also need to respond to a trailCollectionDidChange
message in case the user changes the setting while your app is open:
https://developer.apple.com/documentation/uikit/uitraitenvironment/1623516-traitcollectiondidchange?language=objc
The easier (temporary) solution would be to tell the OS to use light
appearance for your app. It looks like there is an Info.plist key that you
can add which will force your app to use the light appearance. Perhaps that
will help in your situation?
