I'm working in Xcode for the first time in over a decade (coming from VS Code and Zed), so bear with me on this one. I've just started up a new project and got things running, and I'm adding the following struct to my project: struct HttpRequest: Codable { let body: String? let headers: [String: String] let id: UUID let method: HttpMethod let url: String } The UUID type is from Foundation, of course. However, when I hit Ctrl+Space to auto-complete it, it says "Foundation is not imported." If I hit enter to select that entry, it does not auto-import Foundation, and gives me an error that it "Cannot find type 'UUID' in scope". I can click that error and it then click "import Foundation" to add the import, but this seems like a lot of effort just to "automatically" add an import that Xcode is already aware I need to add. On the other hand, I found a number of threads online during my search for answers that suggested I shouldn't even need this import, despite Xcode's insistence. TL;DR, my questions are: 1) Do I need the Foundation import to use UUID in Swift? and 2) If I do need it, how can I auto-import the Foundation module when I auto-complete the UUID type?
