I don't think it's a serious question or the person is very young.
To answer the question. Xcode is the default IDE for iOS development. The default option will always be a practical choice.
JetBrains or Anthropic could get bought by a larger company or dismantled by the government somehow. Should anything happen to Apple (unlikely as that may seem) the entire iOS ecosystem would be gone as well negating any need for a default.
I wish I was young! I have used Xcode in the past. It's just way too slow and anything it does, other IDEs do faster for me.
