How to fix “no valid 'aps-environment' entitlement string found for application” in Xcode 4.3?

Question

I\'ve been trying very very hard to create a simple simple iOS app which can recieve push notifications. My only reason for doing this is to establish a procedure for some

Answer 1

XCode 6.1.1, and multiple apple developer accounts

Another answer for this already fairly comprehensive mix: I came across this issue again today, and this time it was due to my having multiple apple accounts. I needed to first add the 2nd developer account in XCode > Preferences > Accounts > +

Ensure that the Push Notification Capability is ON

Next I needed to actually explicitly enable In-App Purchase in the app (I did not need to do this previously). XCode > (the app window) > Targets > Capabilities > In-App Purchase ON (and at this stage I was given the option to choose the correct certificate)

Note that I had already added the Push enabled certificate by double clicking it in Finder.
