I am using Xcode 5. I am working with push notifications in iOS. I am getting satisfying results for background mode and foreground mode that can be debugged easily on an iO
it takes few seconds:
1- go to edit schema
2- select run section from left list
3- then in info tab goto part launch options
4- select option: wait for executable to be launched
5- then close the window
6- run the app : the app will build but not launched because it's waiting for you to launch the app manually
7- at this time send your notification to your device
8- tap on the notification and your app will launched and the debugger goes to breakpoints you attached in lines of code
