Xcode is an integrated development environment for macOS containing a suite of software development tools developed by Apple for developing software for macOS, iOS, watchOS and tvOS.
Before you can code sign your app, you create your development certificate and later, a distribution certificate to upload your app to iTunes Connect. You can create all the types of certificates and signing identities you need using Xcode. Xcode creates, downloads, and installs your signing identities for you.
