Edit box cursor color indiscernible

I'm developing a Go solution. I have a simple edit box to type in a search. The layout part's background is dark blue with white text. On Pro, the cursor is white, like the text. On Go the cursor is almost the same color as the background, so the user can't tell their cursor is actually in the field and ready for input. I'm running the app on my iPhone connected to my Mac and sharing the file, so I know it is running the same thing. I have created a brand new edit box and it does the same thing - white on Pro, an almost invisible blue on Go.

Any ideas?
