Try This
In my case when i try to set “Silversky Technology” as Attributed text for label from interface builder its not show when i run in simulator but its show in interface builder.
So i used one trick i made Silversky font with 1 pixel bigger then Technology text.
Attribute text have issue with same size of font so change size of 1 word this thing work with me.
May be this is xcode bug but this trick work for me.
