I have a Button inside a NavigationLink with an action called "bindingRequest()". When user.userLoverUID == "", the NavigationLink is dead(The app just died and couldn't do anything). How can I fix it?
import SwiftUI
import FirebaseAuth
import FirebaseStorage
import FirebaseFirestore
import FirebaseFirestoreSwift
struct UserSearchBar: View {
// View Properties
#State private var fetchedUsers: [User] = []
#State private var searchText: String = ""
#Environment(\.dismiss) private var dismiss
#State private var sendRequest:Bool = false
var body: some View {
List{
ForEach(fetchedUsers){user in
NavigationLink{
VStack{
// for showing the selected user's profile
ReuserableProfileContent(user: user)
// Check if userLoverUID == “”，it represents the logged user does't have userLover， then we can send bindingRequest to selected user throw the Button，if userLoverUID !=“”， show the Image only.
if user.userLoverUID == "" {
Button(action: {
// Sending Binding Request
bindingRequest(user:user)
print("Request is sent")
}) {
Image(systemName: sendRequest ? "":"arrow.up.heart.fill")
.resizable()
.scaleEffect(0.9)
.foregroundColor(.blue)
}
}else{
Image(systemName: "heart.slash.circle.fill")
.resizable()
.scaleEffect(0.9)
.foregroundColor(.blue)
}
}
}label: {
Text(user.username)
.font(.callout)
}
}
}
.listStyle(.plain)
.navigationBarTitleDisplayMode(.inline)
.navigationTitle("Search User")
.searchable(text: $searchText)
.onSubmit(of: .search, {
//fetch User from firebase
Task{await searchUsers()}
})
.onChange(of: searchText, perform: { newValue in
if newValue.isEmpty{
fetchedUsers = []
}
})
}
func searchUsers()async{
do{
// let queryLowerCased = searchText.lowercased()
// let queryUpperCased = searchText.uppercased()
let documents = try await Firestore.firestore().collection("Users")
.whereField("username", isGreaterThan: searchText)
.whereField("username", isLessThan: "\(searchText)\u{f8ff}")
.getDocuments()
print("Found Successfully")
let users = try documents.documents.compactMap { doc -> User? in
try doc.data(as: User.self)
}
// UI must be Updated on Main Thread
await MainActor.run(body: {
fetchedUsers = users
print("Got the content")
print(users)
})
}catch{
print(error.localizedDescription)
}
}
//Binding request -> adding userUID to the object's waitingLoverUIDList
func bindingRequest(user:User) {
guard let CurrentuserUID = Auth.auth().currentUser?.uid else{return}
Firestore.firestore().collection("Users").document(user.userUID).updateData(["waitingLoverUIDList": FieldValue.arrayUnion([CurrentuserUID])])
print("saved to waitingLoverUIDList successfully")
sendRequest.toggle()
}
}
struct UserSearchBar_Previews: PreviewProvider {
static var previews: some View {
UserSearchBar()
}
}
It's dead in both simulator and canvas. I tried something:
When I removed bindingRequest() from Button, NavigationLink works, also the Button, but it has no point without the bindingReques().
Removed the Button and used .onTapGesture{bindingRequest()} instead, NavigationLink also died.
Removed ReuserableProfileContent(user: user) from the NavigationLink, it also died.
