GPT-4 Knowledge Cutoff Date?

最近在学习 SwiftData, Chat Mode 中 问了 GPT-4 一些问题, 感觉它并不知道 SwiftData 的存在, 感觉之前发布的 GPT-4 Turbo 的 Cutoff Date 貌似是 23年低,

Recently, I've been learning SwiftData, and in Chat Mode, I asked GPT-4 some questions, and I felt that it didn't know about the existence of SwiftData, and I felt that the Cutoff Date of the previously released GPT-4 Turbo looks like it's 23 years low, and it's a good thing that GPT-4 is not aware of the existence of SwiftData.
