ios - Using Helvetica Neue in WatchKit not working, other custom fonts work -

i wanting use helvetica neue ultra light in watchkit app. have followed of instructions adding custom font (added extension bundle , added in info.plist extension , watchkit app), nothing working , never used.

really strange thing is, other ttf fonts have added work, seems strange issue helvetica.

where helvetica, , why can't add it?

edit: clear things , prevent people think might obvious answers.

watchkit includes system font (san francisco), doesn't expose of fonts ios has. (ref: devforums.apple.com/message/1096179#1096179) why trying include helvetica.

option 1

i had same issue. fixed including - character between font name , name of weight. in ways, xcode recognize font.

try changing helveticaneueultralight.ttf helveticaneue-ultralight.ttf wherever possible (info.plist file , in project folder).

option 2

open fontbook comes included within mac. install font if haven't , closely @ postscript name of font. if differs name using in xcode, change it.

option 3

if can't still working, download same font source.
