Swiftui Dynamic Cloudkit predicate results not filling array - swiftui

Question

I hope someone can help me - I have a dynamic cloudkit array which works fine up until it gets to the List part of my view. In the quertresultBlock when I print returnedItems the records are all there and filtered inline with my predicate. However, the staff array is empty. Its driving me mad. Could someone help please?
struct MarketingModel: Hashable {
let firstName: String
let lastName: String
let country: String
let department: String
let phoneNumber: String
let job: String
let headshot: URL?
let record: CKRecord
}
struct predicateFilter: View {
#State var text: String = ""
#State var staff: [MarketingModel] = []
#State private var countryselected: Country = .Management
var body: some View {
List {
ForEach(staff, id: \.self) { thepeople in
VStack (alignment: .leading) {
Text(thepeople.firstName)
extension predicateFilter {
init(filter: String) {
UISegmentedControl.appearance().selectedSegmentTintColor = UIColor(red: 116/255, green: 152/255, blue: 192/255, alpha: 1.0)
UISegmentedControl.appearance().setTitleTextAttributes([.foregroundColor: UIColor.white], for: .selected)
//func fetchItems() {
//let predicate = NSPredicate(value: true)
let predicate = NSPredicate(format: "department == %#", filter)
let query = CKQuery(recordType: "Staff", predicate: predicate)
query.sortDescriptors = [NSSortDescriptor(key: "lastName", ascending: true)]
let queryOperation = CKQueryOperation(query: query)
var returnedItems: [MarketingModel] = []
queryOperation.recordMatchedBlock = { (returnedRecordID, returnedResult) in
switch returnedResult {
case .success(let record):
guard let firstName = record["firstName"] as? String else { return }
guard let lastName = record["lastName"] as? String else { return }
guard let department = record["department"] as? String else { return }
guard let country = record["country"] as? String else { return }
guard let mobile = record["phone"] as? String else { return }
guard let job = record["job"] as? String else { return }
let imageAsset = record["headshot"] as? CKAsset
let imageURL = imageAsset?.fileURL
returnedItems.append(MarketingModel(firstName: firstName, lastName: lastName, country: country, department: department, phoneNumber: mobile, job: job, headshot: imageURL, record: record))
case .failure(let error):
print("Error recordMatchedBlock: \(error)")
}
}
queryOperation.queryResultBlock = { [self] returnedResult in
print("RETURNED RESULT \(returnedResult)")
DispatchQueue.main.async {
staff = returnedItems
print(staff)
}
}
addOperation(opertaion: queryOperation)
}
func addOperation(opertaion: CKDatabaseOperation) {
CKContainer.default().publicCloudDatabase.add(opertaion)
print("working")
}
