UI Text with "Best Fit" too slow on iOS

Hello
I needed to use new ui Text with “Best Fit” option.
im updating text via code (nothing much, just appending strings like “1+1”,“1+1+1” etc…) and its working ok on Mac & PC but its too slow on iOS (iPhone 5).
when i have tested build with disabled “Best Fit”, it works fast.

Note one of the improvements in beta 21:

  • UI: Best fit mode for Text now uses a binary search instead of an iterative approach, it should be much faster

This could improve things.

Thanks, will test it on beta21
