What is an iOS development certificate?

An iOS developer certificate is a code-signing certificate, a digital signature that associates you and your digital identity with your applications. On the Mac, you must create and submit a request for an iOS development certificate. For more information, see the Apple documentation.

How do I get an iOS code signing certificate?

To get a certificate, you need to generate a Certificate Signing Request with Keychain Access and send it to Apple. This will create a public/private key for you if you don’t have one already. Apple will then verify the information, and create a certificate for you.
