apple watch - WatchOS app running in background -

-

how keep apple watch app running in background. build timer, every time screen dims , wake app resets timer. how avoid this?

i don't think you're supposed to.

apple say:

  • do not use background execution modes technology. watch apps considered foreground apps because run while user interacts 1 of interfaces. result, corresponding watchkit extension cannot take advantage of background execution modes perform tasks.

you might want check elapsed time on wakeup instead.
