This shouldn’t be a domain name, right? What I understand is that the Bundle Identifier after the project is created needs to be matched. Each APP has and has only one Bundle Identifier to identify the APP. When you apply for a certificate, you need to provide this APP ID. For this Bundle Identifier, it is just customary to use a writing method similar to the domain name. In fact, it has nothing to do with the domain name. For example, the Boundle Identifier of my project is not actually a valid domain name, but I am just used to writing it in this format. The Boundle ID you fill in here needs to correspond one-to-one with the Boundle Identifier.

The company’s domain name is just an identifier. Writing the company's domain name can greatly reduce the chance of conflict.
