Meine Anwendung zerschlägt, wenn ich in diesem Controller den Fehler erhalte: App aufgrund der nicht abgefangenen Ausnahme beenden' NSInternalInconsistencyException ', Grund:' versuche Zeile 0 in Abschnitt 0 einzufügen, aber es nur 0 Zeilen in Abschnitt 0 nach dem Update‘sind so dass ich ein Problem mit dem Tableview habe, ist die Klasse dieser:Beenden der App aufgrund der nicht abgefangenen Ausnahme 'NSInternalInconsistencyException (Swift)

einen Haltepunkt hinzugefügt ich sah, dass der Andrang in diesem func ist:
func insertRowMode3(ind:Int) {
let indPath = IndexPath(row: ind, section: 0)
rows = ind + 1
tableView.insertRows(at: [indPath], with: .right)
guard ind < places.count-1 else { return }
DispatchQueue.main.asyncAfter(deadline: .now()+0.20) {
self.insertRowMode3(ind: ind+1)
}
}
genau auf dieser Linie:
tableView.insertRows(at: [indPath], with: .right)
ich weiß nicht, wie ich diese Funktionen ändern muß, um das Problem zu lösen, ich sah mich um bereits auf andere Fragen, aber nicht etwas Nützliches finden. andere Klassen, die mit diesen UIViewController arbeiten, sind:
struct QCategoryy {
var name:String
init(name:String) {
self.name = name
}
}
extension QCategoryy: ExpressibleByStringLiteral {
init(stringLiteral value: String) {
self.name = value
}
init(unicodeScalarLiteral value: String) {
self.init(name: value)
}
init(extendedGraphemeClusterLiteral value: String) {
self.init(name: value)
}
}
und

if let name = name {
s.append("Name: \(name)")

if let vicinity = vicinity {

if let types = types {
s.append("Types: \(types.joined(separator: ", "))")
}
if let isOpen = isOpen {

return s.joined(separator: "\n")

let rect = NSString(string: desc).boundingRect(with: CGSize(width: width, height: CGFloat(MAXFLOAT)), options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

Sie wissen, wo ist der Fehler in meinen Funktionen? – seran
