From Crashlytics I know at least human readable format of this error
Fatal error: Duplicate keys of type 'Contact' were found in a Dictionary. This usually means either that the type violates Hashable's requirements, or that members of such a dictionary were mutated after insertion.
I 've checked all my parts of code where Im using dictionary. This is a function which creating that particulary dictionary.
private func logsByDate() {
let groupedByDate = Dictionary(grouping: logs.filter { ($0.remoteParty as? Contact != nil) } ) {
$0.date.removeTimeStamp ?? .distantPast }.mapValues {
$0.compactMap { $0 }
}
var dayLogs = [DayLog]()
for date in groupedByDate {
var contacts = [CallLogContact]()
for log in logs.filter({ $0.date.removeTimeStamp ?? .distantPast == date.key }) {
if let contact = log.remoteParty as? Contact {
if contacts.firstIndex(where: {$0.contact == contact }) == nil {
let contactDayLogs = logs.filter({ $0.remoteParty as? Contact == contact && $0.date.removeTimeStamp == date.key})
contacts.append(
CallLogContact(
contact: contact,
logs: contactDayLogs,
lastCallLogDate: contactDayLogs.sorted(by: {$0.date > $1.date}).first?.date ?? .distantPast
)
)
}
}
}
dayLogs.append(DayLog(date: date.key, contact: contacts))
}
DispatchQueue.main.async {
self.groupedCallLogs = dayLogs
}
}
This function is called from 3 others functions based on notification from the server in case of new call log, fetched call logs and removed call logs.
