I'm using xcode 16 with swift. I'm trying to call a function in another file. It used to work. Now I'm getting: Cannot find 'detailline' in scope. Detailline is the function I'm calling. I just added variables to the top. I have since deleted them. Please help.

How can I add navigation to an existing program. I coded this as per youtube video: var body: some View { NavigationView { VStack { NavigationLink(destination: viewdetail()) { Text("click") .frame(width: 300, height: 150, alignment: .center) .background(Color.gray) .foregroundColor(.black) } } } It doesn't work. If I comment out the rest of the program it works. I have VStacks and HStacks and functions after the navigation code. Please help.

I'm using xcode 16.1 with SwiftUI. I have a program that needs another screen. How can I add navigation? All the youtube videos show you how to add navigation to a new program. Is there a video that shows you how to add navigation to an existing program? Any instruction would help. Thanks

I'm using XCODE with Swiftui. I want to know how I can format percentages in the program to whole numbers with a % sign without any decimal places to the screen. For instance if the program figures 33.3333 I want to print 33% to the screen. If I have 67.85762 in the program I want to print 67% (or 68% if it can be rounded) to the screen. Please help. Thanks

I have a program where the user enters 2 fields with numerics. If they accidently enter a letter the program crashes. How can I check for NIL without making the variable optional. If I make it optional I get an error in the Textfield. How can I test a Textfield for NIL? Please help.

I want to print a percentage to the screen. How can I only print 2 decimal places.

How can I put navigation into an existing program?
