Have an Apple ID

To develop for iOS you need a Mac computer to develop on, and an Apple ID to log into the App Store. This will permit you to build iOS apps that run on your personal device.

It is also recommended that you have an Apple Developer account. It costs $99 USD per year but is your admission ticket to the tools and services including setup provisioning profiles needed to share and test your app on other devices.
