WatchKit Use App Groups To Store Data

Question

I am working on my app to get ready for Apple Watch. I use Parse in my app, and instead of allowing user to try and login with their watch, I just want it to use the PFUser data from the iPhone. If they're logged in, it detects the PFUser the iPhone is currently using, if not, it prompts them to log in on the iPhone. My question is, what is the best way to handle passing of data for this? NSUserDefaults or App Groups?

Answer 1

I think you need enable the app group, and then you can access NSUserDefaults from app group. you can use

let sharedUserDefaults = NSUserDefaults(suiteName:"<group identifier>")

replace "<group identifier>" to your app group identifier, you can find it in your apple develop Identifiers link. Then you can use the "sharedUserDefaults" to set or get anything you want use.
