Can I send you the whole program? Or should I post it here?

I'm going to post the whole program in 2 or 3 parts.

Part 1. import SwiftUI struct ContentView: View { @State var tipa: [Double] = [] @State var costa: [Double] = [] @State private var cost = "" @State private var costt = Double?(0) @State private var paidt = Double?(0) @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 deletep = 0 @State var number = 0 @State var msg = "Enter cost and how much was paid. Enter numbers" @State var msg2 = " and one . decimal point only. Then press enter." @State var emsg = "" var body: some View { NavigationStack { VStack { Text(" " + Date().formatted(date: .numeric, time: .omitted)) .foregroundColor(.black) .fontWeight(.bold) Text("Driver's Food Delivery") .font(.largeTitle) .fontWeight(.bold) Image("Screenshot 2024") HStack { Text("Cost") .font(.largeTitle) .padding(10) Spacer() Text("Paid") .font(.largeTitle) .padding(10) Spacer() Text("Tip") .font(.title) Spacer() Text("Tip %") .font(.title) } HStack { TextField("Cost", text: $cost) .frame(width: 75, height: 25) .padding(20) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) .background(Color.brown) .cornerRadius(025) TextField("Paid", text: $paid) .frame(width: 75, height: 25) .padding(20) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) .background(Color.brown) .cornerRadius(025) Text(tipp) .frame(width: 95, height: 25) .background(Color.white) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Text(tipc) .frame(width: 75, height: 5) .padding(10) .background(Color.white) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) } VStack { Text (emsg) .foregroundColor(.red) Text (msg) .foregroundColor(.blue) HStack { Text (msg2) .foregroundColor(.blue) Spacer() } Button { enterp() } label: { Text("Enter") .font(.largeTitle) .foregroundColor(.green ) } NavigationLink(destination: viewdetail()) { Text("Detail") .frame(width: 100, height: 50, alignment: .center) .background(Color.white) .foregroundColor(.blue) .font(.largeTitle) } Button { delete(costa:&costa,tipa:&tipa, number: &number) } label: { Text("Delete") .font(.largeTitle) .foregroundColor(.red) } } VStack { Spacer() HStack { Spacer() Text("Avg Tip") .font(.title) Spacer() Spacer() Text(" Tip %") .font(.title) Spacer() Text(" #") .font(.title) Spacer() } HStack { Spacer() Spacer() Spacer() Text(tipaa) .frame(width: 145, height: 25) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Spacer() Spacer() Text(tipcc) .frame(width: 120, height: 5) .padding(10) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Spacer() Text(numbc) .frame(width: 55, height: 5) .padding(10) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Spacer() } }

Part 2. VStack { Spacer() HStack { Text("Total") .font(.title) Spacer() Text("Total") .font(.title) Spacer() Text("Total ") .font(.title) } } VStack { HStack { Text("Cost") .font(.title) Spacer() Text("Tips") .font(.title) Spacer() Text("Cash") .font(.title) } } HStack { Text(totalcost) .frame(width: 145, height: 25) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Spacer() Text(totaltips) .frame(width: 145, height: 25) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) Spacer() Text(totalcash) .frame(width: 165, height: 25) .fontWeight(.bold) .font(.system(size: 22)) .foregroundColor(.blue) } Spacer() } } } func enterp() { @Binding var text1: String var ipc = 50.0 var ipcc = 50.0 var tippp = 0.0 var totalcsh = 0.0 var ttips = 0.0 var tcost = 0.0 var tipo = 0.00 costt = Double(cost) paidt = Double(paid) emsg = "" if (costt != nil) && (paidt != nil) { tipo = (Double(paid)! - Double(cost)!) tipa.append (tipo) costa.append (Double(cost)!) number += 1 numbc = String(number) ttips = (tipa.reduce(0, +)) tcost = (costa.reduce(0,+)) tippp = (ttips / Double(number)) tipaa = tippp.formatted(.currency(code: "USD")) totaltips = ttips.formatted(.currency(code: "USD")) totalcost = tcost.formatted(.currency(code: "USD")) tipp = tipo.formatted(.currency(code: "USD")) tipc = String(tipo / Double(cost)! * 100) ipc = Double (tipc)! tipc = String(format: "%3.0f%%", ipc) tipcc = String(ttips / tcost * 100) ipcc = Double (tipcc)! tipcc = String(format: "%3.0f%%", ipcc) totalcsh = (tcost + ttips) totalcash = totalcsh.formatted(.currency(code: "USD")) } else { emsg = "Enter numbers and 1 decimal point only." } // detailLine(costa: &costa,tipa: &tipa) } } } #Preview { ContentView() }

Part 3 viewdetail.swift import SwiftUI struct viewdetail: View { @State var text1:String = "" @State var tip1:String = "" @State var text23:String = "" @State var tip23:String = "" var body: some View { Text(text1);Text(tip1);Text(text23);Text(tip23) } func detailLine(costa:inout [Double],tipa:inout [Double]) { print(costa,tipa) text1 = "125" print("detail") } } func delete(costa:inout [Double],tipa:inout [Double],number: inout Int) { print(costa,tipa) tipa.removeLast() costa.removeLast() number -= 1 print(costa,tipa) } #Preview { viewdetail() }

I don't know how to do this.Let's assume the view that contains enterp() is called AnotherView. Then, in AnotherView define a Binding @Binding var text1ForUpdate: String // To make it easier to understand, I've not named it text1, but you could declare detailLine inside AnotherView somewhere in ViewDetail you call AnotherView pass the text1 as parameter: AnotherView(text1ForUpdate: $text1) Change ne name in detailLine func: text1ForUpdate = "125" Tell if that works now. Please help!!

Yes I read all answers but I don't understand them. I didn't try the code I received in the last posts. I don't know how to try.

Can you answer https://developer.apple.com/forums/thread/771150?

Can you explain this please. Let's assume the view that contains enterp() is called AnotherView. Then, in AnotherView define a Binding @Binding var text1ForUpdate: String // To make it easier to understand, I've not named it text1, but you could declare detailLine inside AnotherView somewhere in ViewDetail you call AnotherView pass the text1 as parameter: AnotherView(text1ForUpdate: $text1) Change ne name in detailLine func: text1ForUpdate = "125"

Please answer.

I put all your suggestions in except for Gridrow. There were too many errors including g.size cannot be found in scope. Now I just have to put in Another View. All I did was create an array with 44 texts. Please help me.

There's too many replies in here. I'm going to post elsewhere.

No please help me. I got dementia. I'm willing to try your responses I just don't know how. Please just this one last time. I won't bother you anymore.

You're right. I didn't see GeometryReader that was added further up. I'm going to try to put GridRow back in.

I did it. GridRow is back in. No errors. It looks great. Sometimes if the number in the field was too big I would get $121.... Now I get $121.75. I never get .... Also the cost field is not on the edge of the screen. Thank you.
