I get this type of error when I write any iteration statements.
the NavigationView and scrollview braces are closed below.
iam seeing some of the images but not in every row or column any answers.
And any ideas on how to print text below every image like a description, I tried in one of them writing denim but it didn't work.
Like this:-
I want to create a view in which if I scroll images the text below stays and the images also come over another how to make it?
import SwiftUI
struct menjeans: View {
var menje:[UIImage] =
[UIImage(named:"IMG_9917")!,
UIImage(named:"IMG_9920")!,
UIImage(named:"IMG_9923")!]
let layout=[GridItem(.flexible()),GridItem(.flexible())]
var body: some View
{
NavigationView
{
ScrollView(.vertical)
{
LazyVGrid(columns: layout,spacing: 2)
{
ForEach(menje, id: .self)
{
imager in
maincustom(content: Image(uiImage:imager), text: "df")
}
.navigationBarTitle("Men")
}
}
}
}
}
struct menjeans_Previews: PreviewProvider {
static var previews: some View {
menjeans()
}
}
I want the image I clicked in the first view to the last view as main image.
First View
Clicked on image
Last View
Code for it is below:
//This is the First View
import SwiftUI
struct kidtshirt: View {
var clothimages:[UIImage] =
[UIImage(named:"IMG_9981")!,
UIImage(named:"IMG_9985")!,
UIImage(named:"IMG_9987")!]
var tshirt:[String]=["PLAIN T-SHIRT\n₹590.00","PRINTED T-SHIRT\n₹790.00","JACQUARD DAISY PRINT T-SHIRT\n₹1,090.00"]
let layout=[GridItem(.flexible()),GridItem(.flexible())]
var body: some View
{
// NavigationView
// {
ScrollView(.vertical)
{
LazyVGrid(columns: layout,spacing: 2)
{
ForEach(Array(zip(clothimages,tshirt)), id: .0)
{
(imager,texter) in
NavigationLink(destination:lastview()){maincustom(content: Image(uiImage:imager), text: texter)
}
}
.navigationBarTitle("Kid Tshirt")
}
}
.navigationBarBackButtonHidden(true)

}
}
//This is the Last View
import SwiftUI

Text(texty)
.multilineTextAlignment(.leading)
}
}
}
ForEach with 2 arguments
If I try more than 2 arguments I get error that there are extra arguments.
And even tried using two for each together.
Help me how to use foreach together as I want to do it together.
I want the details entered in textfield and password should stay even after changing the view or closing the app and the person should be logged in even after he closes the app, Can anyone help me out?

how to stop the view from moving down on screen on every open?
this below is the view which doesn't remove the columns after I click the delete button and it shows the data even after it is removed from the firestore unless relaunched the app.
import SwiftUI

guard let uid = Firebase.Auth.auth().currentUser?.uid else {
return
}
FirebaseManager.shared.firestore.collection("users").document(uid).collection("product").getDocuments{snapshot,error in
if error==nil{
//no errors
if let snapshot = snapshot{
//update the user property in the main thread
DispatchQueue.main.async {
// //get all the documents and create user
self.use=snapshot.documents.map{ d in //map will iterate over array and perform code on each item
//create an new user for each document returned
return user(id: d.documentID,productnm: d["product name"] as? String ?? "",
quan: d["quantity"] as? String ?? "")
}
}
}
print("no data found")
}
else{

}
}
}
}
