Error launching 'Watchkit extension" - SPErrorUnknownMessage

Trying to run Watchkit - Notification. Receiving the following error:

Error launching 'Watchkit extension" - SPErrorUnknownMessage

Has anybody else come across this error before or knows what it means? Haven't been able to find anything online about it.

Cheers, A

This error occurs due to PushNotificationPayload.apns. Sometime closing quote may be missing.

I got this message when I removed the file PushNotificationPayload.apns from the WatchKit Extension in Xcode.

Take a look into the Run-Section the Schema: If the Watch Interface entry shows something like Dynamic/Static Notification, it will likely expect some apns-file as notification payload. If that file is missing (or faulty as for Gavin Potts), you'll get that error.

So either fix the apns file, or change the Watch Interface entry to Main or sth. else.

I have seen this issue and it was related to an error in the structure of my .apns file - there was a comma missing in the json. Once this was corrected, notifications worked again.

Try looking for errors in the Payload apns file that you are using for this target.
