I am using SwiftUI to make an app and storing the data on ICloud. Because all the code I can find relates to Swift and viewDidLoad and TableView, however this do not apply. I have written code and seems to retrieve it but will not return it to the ObservableObject to be able to display in the SwiftUIThe ObservableObject file:-import SwiftUI
import Combine
final class ObservedData: ObservableObject {
@Published var venues = venuesData
}The query to retrieve dataimport SwiftUI
import CloudKit
var venuesData: [Venue] = loadVenues()
func loadVenues() -> [Venue] {
var data = [Venue]()
let pred = NSPredicate(value: true)
let sort = NSSortDescriptor(key: "id", ascending: true)
let query = CKQuery(recordType: "DeptfordHopData", predicate: pred)
query.sortDescriptors = [sort]
let operation = CKQueryOperation(query: query)
operation.desiredKeys = ["id","name", "address"]
operation.resultsLimit = 50
var newVenues = [Venue]()
operation.recordFetchedBlock = { record in
let venue = Venue()
venue.racordID = record.recordID
venue.id = record["id"]
venue.name = record["name"]
venue.address = record["address"]
newVenues.append(venue)
}
operation.queryCompletionBlock = {(cursor, error) in
DispatchQueue.main.async {
if error == nil {
data = newVenues
} else {
print(error!.localizedDescription)
}
}
}
CKContainer.default().publicCloudDatabase.add(operation)
return data
}I have got data showing when do breakpoint at line 40 in data but does not return to venueData
