PFQuery findObjectsInBackgroundWithBlock: WatchKit app runs in simulator, not watch, unless iOS app is in foreground
I am writing a WatchKit application that needs to make a request to our Parse server. Since this is a network call, I follow this procedure:
- I am making a call from WatchKit to an iOS app using
I run a background job with
to ensure the iOS app terminates immediately.
- I installed
mine and call
- In the block I go to PFQuery, I will reply the relevant information to the watch
I wrote this app maybe a month ago before the Apple Watch came out and it did a great job with the Watch simulator. I got my Apple Watch yesterday and I managed to get the app to work on the watch, but it didn't quite work - I was able to figure out that when the iOS app is actively running in the foreground on the iPhone, then everything is Great; but if the app is inactive (for example, in the background or exited), then it
never calls the block, and execution seems to just stop.
Does anyone have any idea what might be going on? My initial thought was that the iOS app pauses / kills before it can complete the request, but I was confident that the background task would prevent this.
PS. If anyone stumbles upon this question because they were looking for how to get the WatchKit app on a real watch, I found this post extremely helpful in getting it working.

It turned out that I had several problems with openParentApplication: reply: and they all seemed to have been fixed using the technique from this post:
I started a background job for my own application, but I didn't use the "dummy workaround" focus task described in this post because it wasn't necessary for me in the simulator. However, it appears to have been on the clock.
