My understanding is that the iOS service worker does not support background sync or a periodic sync. ( if this is not true please point me to the documentation that describes the support of these features... )
High level use case.
My users of my app will be filling out forms during the day while off line ( out of cell phone coverage )... then at the end of the day they will travel back into coverage at which point the WEB app would automatically send those POSTS without User interaction. How would you accomplish this on an iOS device... ( key is without having to relaunch the app )
thank you
