Now that you’ve written your first iOS application and run it on the simulator, it’s time to deploy it to a device.

To install an application on your development device, you need a developer certificate from Apple. Developer certificates are issued to registered iOS Developers who have paid the developer fee. This certificate grants you the ability to sign your code, which allows it to run on a device. Without a valid certificate, devices will not run your application.

Apple’s Developer Program Portal (http://developer.apple.com) contains all the instructions and resources to get a valid certificate. The interface for the set-up process is continually being updated by Apple, so it is fruitless to describe it in detail. Instead, use the Development Provisioning Assistant, a step-by-step guide available on the program portal.
