Updating specific list item after patch request Swift, SwiftUI - swift

Question

I'm using GitHub api to
get issues
update issue title or description
I call self.get() inside update() method, to get the updated list of issues after the successful update.
But after update when I get back to screen with list of issues, its title/description shows the previous values.
Could you please say how can I fix it? Thanks!
Here is the model:
struct Issue: Codable, Hashable {
let id: Int
let number: Int
var title: String
var body: String? = ""
}
ViewModel:
class ViewModel: ObservableObject {
#Published var issues: [Issue] = []
private let token: String = "_token_"
init() {
get()
}
func get() {
guard let url = URL(string: "https://api.github.com/repos/\(repoOwner)/\(repo)/issues") else {
return
}
var request = URLRequest(url: url)
request.httpMethod = "GET"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/vnd.github+json", forHTTPHeaderField: "Accept")
request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
URLSession.shared.dataTask(with: request) { [weak self] data, response, error in
guard let data = data, error == nil else {
return
}
do {
let response = try JSONDecoder().decode([Issue].self, from: data)
DispatchQueue.main.async {
self?.issues = response
}
} catch {
print("error during get issues \(error.localizedDescription)")
}
}.resume()
}
func update(number: Int, title: String, body: String) {
guard let url = URL(string: "https://api.github.com/repos/\(repoOwner)/\(repo)/issues/\(number)") else {
return
}
let json: [String: Any] = ["title": "\(title)",
"body": "\(body)"]
let jsonData = try? JSONSerialization.data(withJSONObject: json)
var patchRequest = URLRequest(url: url)
patchRequest.httpMethod = "PATCH"
patchRequest.addValue("application/vnd.github+json", forHTTPHeaderField: "Accept")
patchRequest.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
patchRequest.httpBody = jsonData
URLSession.shared.dataTask(with: patchRequest) { data, response, error in
guard let data = data, error == nil else {
return
}
let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
if let responseJSON = responseJSON as? [String: Any] {
print(responseJSON)
}
self.get()
}.resume()
}
}
Views
List of issues:
struct HomeView: View {
#EnvironmentObject var viewModel: ViewModel
var body: some View {
NavigationView {
List {
ForEach(viewModel.issues, id: \.id) { issue in
NavigationLink(destination: EditView(issue: issue)) {
IssueRow(issue: issue)
}
}
}
.navigationTitle("Github issues")
}
}
}
struct IssueRow: View {
var issue: Issue
var body: some View {
VStack {
HStack {
Text("#\(issue.number)")
.bold()
Text("\(issue.title)")
.bold()
.lineLimit(1)
Spacer()
}.foregroundColor(.black)
HStack {
Text(issue.body ?? "no description")
.foregroundColor(.gray)
.lineLimit(2)
Spacer()
}
Spacer()
}
}
}
Edit view:
struct EditView: View {
#Environment(\.presentationMode) var presentationMode
#EnvironmentObject var viewModel: ViewModel
var issue: Issue
#State var title: String = ""
#State var description: String = ""
func save() {
viewModel.update(number: issue.number, title: title, body: description)
dismiss()
}
func dismiss() {
presentationMode.wrappedValue.dismiss()
}
var body: some View {
Content(issue: issue, title: $title, description: $description, save: save)
}
}
extension EditView {
struct Content: View {
var issue: Issue
#Binding var title: String
#Binding var description: String
let save: () -> Void
var body: some View {
VStack {
List {
Section(header: Text("Title")) {
TextEditor(text: $title)
}
Section(header: Text("Description")) {
TextEditor(text: $description)
.multilineTextAlignment(.leading)
}
}
saveButton
}
.onAppear(perform: setTitleAndDescription)
.navigationTitle("Update issue")
}
var saveButton: some View {
Button(action: save) {
Text("Save changes")
}
}
func setTitleAndDescription() {
self.title = issue.title
self.description = issue.body ?? ""
}
}
}
