    I believe the “no valid ‘aps-environment’ entitlement string found for application” error appears when you don’t sign your app with the correct provisioning profile. You’ll have to generate a profile for your app as described in Mahesh‘s link). Also note that you can’t use a team provisioning profile to sign an app that requires push notifications.
