Hello World ! I figured out some issues in my code : I want to got to a specific view after pressing a button. In fact I cannot use the traditional NavigationLink because I need to do some stuff before. It's like a dismiss function but if I use the @Environment(\.dismiss) var dismiss it goes to the wrong view. So there is my code : Button("Save"){ print("Save") checkCondition() if !showAlert{ addToBase() showAchievement = true Timer.scheduledTimer(withTimeInterval: 1.01, repeats: false) { _ in showExhibitView = true } } } So after the timer I need to display the ExhibitView. Plz Help me !

Hello everyone, for a personal project I'd like to reproduce a design element from Apple's saving application. I'd like to display three rectangles containing text: two horizontally aligned and one next to it. And I'd like the height of the last rectangle to be equal to the height of the two smallest. Does anyone have a solution? Please provide a sample code

Hello everyone, I'm working on a fun project for my teacher and want to give my software an Apple-inspired look. Specifically, I'm trying to create image buttons similar to Apple's design (as shown in the image). I need a button with an image that darkens its background when the user hovers over it with the mouse. Any suggestions on how to achieve this effect would be greatly appreciated. For now, I have this code : import SwiftUI struct StudentRow: View { @Environment(\.modelContext) private var modelContext var student: Student @State private var isHover = false var body: some View { HStack { Text(student.name) Image(systemName: "xmark") .opacity(isHover ? 0.9 : 0.1) .bold() .onTapGesture { deleteStudent(student, modelContext: modelContext) } .onHover { hovering in isHover = hovering } } .padding() } } However, I'm not entirely satisfied with the outcome of this code. (Trust me, the outcome is the same when using the magnifying glass icon) plz help
