New feature Dark mode on iOS 13.x
I put my project targeting for iOS 12.4 on my iOS 13.1 device to check.
Build was succeeded and launch process was as usual. But, I noticed that the date picker and some button were lost in the dark mode.
After one or two hours, I found a solution for it. This solution is not perfect one, but I like it finally.
It was that change the background color to other than default white one. I chose Light Gray and it looked fine non-dark mode too.
Dark mode on iOS 13 may hide some widgets in runtime. We should take into account of it.
