I'm writing a new iOS app. I want to use some fonts(included in the system font list) except SF serial. I'm curious about whether it's legal for me to use the font without paying for the license.

Sorry for my poor English. I actually want to know how to switch the "5\n" to "(5 times)". I remember it used to display like that in the past. However, I can only switch in between "latest value" and "value history" for now. Is it changed because of the Xcode version. Or I'm looking in the wrong place
