var name: String? = "name" if let copyname = name { print(copyname) } In this code, are name and copyname allocated in two different memory?

I wonder how the + function is used directly. extension CGPoint {     static func add(lhs: Self, rhs: Self) -> CGPoint {         CGPoint(x: lhs.x + rhs.x, y: lhs.y + rhs.y)     }     static func +(lhs: Self, rhs: Self) -> CGPoint {         CGPoint(x: lhs.x + rhs.x, y: lhs.y + rhs.y)     } } private func testCGPoint() {     let dummy1 = CGPoint(x: 2, y: 3)     let dummy2 = CGPoint(x: 4, y: 5)     let dummy3: CGPoint = .add(lhs: dummy1, rhs: dummy2)     let dummy4: CGPoint = dummy1 + dummy2 } in my expectation, I thought that the + function would be used like the add function. i thought this form. CGPoint.+(lhs: dummy1, rhs: dummy2) But the + function did not. How are you doing this?

The professor codes like this in the lecture var number: Int { return 3 } what's different about this? var number: Int = 3

I'm sorry I don't speak English well, so I use a translator so sentences may be awkward. I am a Korean college student who likes swift. Most Korean men go to the military. So next year I will take a leave of absence from university and I will be one of them. But, I would like to participate in the annual WWDC swift student challenge. Is it possible for me to participate and win? If I take a leave of absence and participate as a soldier, is it impossible to receive the award?

I want to get real time camera frames to apply machine learning in swiftui. i made camera app with swiftui like this. but, i don't know how to get camera frame and how to apply machine learning techniques to camera frames struct ImagePicker: UIViewControllerRepresentable {       var sourceType: UIImagePickerController.SourceType = .camera       func makeUIViewController(context: UIViewControllerRepresentableContext) -> UIImagePickerController {           let imagePicker = UIImagePickerController()         imagePicker.allowsEditing = false         imagePicker.sourceType = sourceType           return imagePicker     }       func updateUIViewController(_ uiViewController: UIImagePickerController, context: UIViewControllerRepresentableContext) {       } }

i'm learning about swiftui and machine learning(by python pytorch). I want to use machine learning in swiftui like coreml or vision. but, almost reference of coreml or vision are written in uikit. so, any references(book or lecture or document, yotube) to machine learning with swiftui?
