The markup above produces this layout on iOS:

As you can see the first Label is cut off after "v". Add a couple more characters to the string and the Label wraps properly and the full string is displayed.
This was in the iPhone 7 simulator. Other screen sizes will work/break with different string lengths.
I have a demo project here showing the issue: https://github.com/3rror404/ns-flexbox-issue
