Got this debug info when debug a today extension app

"host connection < NSXPCConnection: 0x170113560 > connection from pid 53 invalidated"

Answer 1

NSXPCConnection API is used to perform interprocess connection between Xcode client and your app on iPhone. So you do not need to worry about this one.

Link: https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingXPCServices.html

So there may be 2 reasons that your widget is terminated.

1. You need to call completionHandler(NCUpdateResultNoData); right after your widgetPerformUpdateWithCompletionHandler has been called even when the response hasn't been returned.

2. Your app is terminated because of the automatic app termination. It terminates the widgets/apps for 2 reasons:

a. It terminates apps that are not being used and allowing the reclamation of resources such as memory.

b. It terminates widgets that use too much memory.
