Xcode 9 custom fonts not working

Question

Custom fonts not working in Xcode 9. However if I open the same project in Xcode 8, the custom fonts work as expected

I\'ve ran this piece of code to ensure the font

Answer 1

It presents a problem for the compiler if it is located inside a blue directory folder (apparently) I moved my font file outside the folder, build and problem solved (GRR!)
