You dont need rich text if all you want to do is line breaks. add a \n
for a newline. So:
layer.text=@"The article was about employment. He leafed through it in an instant. His feeling of anxiety resurfaced and he closed the magazine.\n\n-Hm…, he breathed.\n\n-Have you been looking for work long?, asked the stranger at his side."
Real Rich Text isn't possible AFAIK
