Not Receiving Push Notifications (And Out of Troubleshooting Ideas) - ios

Question

I have what seems like should be a working push notification in an iOS app. Here's the meat of it. What's driving me nuts is that everything appears to work, except that my breakpoints are never hit in the message receiver functions; device registration with Google Cloud Notifications is successful, the initialization code appears to work and I even get "Success" messages back from the GCM service.
STILL, I never seem to actually get the message in my app. Note, I'm running it in an iPad connected to my Mac and everything seems kosher/enabled in Notifications settings. Also, I'm using the dev certificate to match the kGGLInstanceIDAPNSServerTypeSandboxOption:true option.
What could I be missing?

Message sent to https://gcm-http.googleapis.com/gcm/send. The payload is arbitrary/copied from a sample.
{
"content-available":1,
"data": {
"score": "5x1",
"time": "15:10"
},
"to" : "<<the registration token resulting from the code above>>"
}
...which results in the reply:
{
"multicast_id": 12345...,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "some ID"
}
]
}
Any ideas?

Please try following command in your terminal by substituting your GCM registration token and Server API key.. this command helps me.
Please make sure payload dictionary must be notification not
data
curl --header "Authorization: key=” https://android.googleapis.com/gcm/send -d '{"to”:””,”priority":"high”, “notification":{"title”:”TEST TITLES”,”body":"Wow ! your first message tested.","badge":"1","sound":"default"}}'
Also try checking by app sending in background CMD + H
