Xcode font disappeared

Question

I imported my fonts on my project (Roboto), it worked with my first ViewController, but now Roboto disappeared of my Custom Fonts. Now when I want to modify my font, the font changed to Helvetica.

I don't understand how it happened, I didn't change the fonts folder.

Answer 1

I had the same problem, also using Roboto. After restarting Xcode the font reappeared.

Answer 2

No need to reinstall the font, since it's already added to the project. Just quit Xcode and delete DerivedData then start Xcode again. The custom font should be ok. I delete the whole DerivedData folder, since Xcode will generate it automatically.

rm -rf ~/Library/Developer/Xcode/DerivedData
