How can I put navigation into an existing program?
navigationstack
By typing the code into the existing program...
Sorry, but how do you expect us to help you with just that one-liner?
You need to tell us way more information than that.
Where does the code go? I'm using xcode 16 with swiftui. I started writing a program that keeps track of pizza deliveries. I got the first screen done but now I need to go to another screen where I will list all the deliveries and tips. On the first screen the user enters the cost of the delivery and what he got paid. The app then figures out the tip, tip%, avg tip, total tip %, how many deliveries, total cost and total tips. There's a button that says detail. This should take him to the second screen that will list all the deliveries and all the tips, high tip and low tip. Please let me know what other information you need. Thanks for your help.
We need to see your code!
Bringing robust navigation structure to your SwiftUI app and The SwiftUI cookbook for navigation WWDC session is a great place to start learning about NavigationStack. Review those resources and let us know if you need any additional help.
Thanks for your response. I need additional help. I have a screen and just want to go to another screen. I need step by step instructions. The video doesn't tell me where to put the code and he went too fast. Thanks again.

Darkpaw, I'm having a problem sending the code in here. Can I have your email address? I can email it. My email is robert0605. You have to put aol.com after robert0605. Thank you
Darkpaw, Code is too big to send in 1 text. I have to send 2.import SwiftUI struct ContentView: View { @State var tipa: [Double] = [] @State var costa: [Double] = [] @State private var cost = "" @State private var paid = "" @State var tipp = "" @State var tipc = "" @State var tipaa = "" @State var totalcost = "" @State var totaltips = "" @State var totalcash = "" @State var tipcc = "" @State var numbc = "" @State var number = 0 @State var msg = "Enter cost and how much was paid.

Darkpaw,
You got my code. What else do you need?
