Why Xcode 11 has suffix GM Seed ?

Recently I want to download Xcode 11 beta and went to developer site to download it. And I saw that Xcode named as Xcode 11 GM Seed which is never seen before. I want to know What is purpose and meaning of this name ?
If anyone knows, could you please let me know.
