I'm setting up my first Firestore database and I have several date fields stored as timestamps. In my swift struct, the corresponding properties are declared as Date. First question - is that the correct way to do it? if so, how do I fetch those timestamp values? I've been trying to find the solution but it does not seem to be obvious solution.
struct HealthLog1: Codable {
var comment: String?
var entryDate: Date?
var familyMemberID: String?
var logID: String?
var user_ID: String?
}
db.collection("healthLogs").whereField("familyMemberID", isEqualTo: person.familyMemberID!).getDocuments { (snapshot, error) in
if error == nil && snapshot != nil {
for doc in snapshot!.documents {
let log = HealthLog1(
comment: doc["comment"] as? String,
entryDate: doc["entryDate"] as? Date,
familyMemberID: doc["familyMemberID"] as? String,
logID: doc["logID"] as? String,
user_ID: doc["user_ID"] as? String)
healthLogs.append(log)
}
self.delegateHLP?.receiveLogs(healthLogs: healthLogs)
}
else {
print ("there is some error with the get documents")
}
}
}
Declare date as a Timestamp.
Your model
class HealthLog1: Codable {
var comment: String?
var entryDate: Timestamp? //<-- Declare Timestamp
var familyMemberID: String?
var logID: String?
var user_ID: String?
}
Init
let log = HealthLog1(
comment: doc["comment"] as? String,
entryDate: doc["entryDate"] as? Timestamp,
familyMemberID: doc["familyMemberID"] as? String,
logID: doc["logID"] as? String,
user_ID: doc["user_ID"] as? String)
If you need date from Timestamp value then use dateValue()
:
let entryDate = log.entryDate.dateValue()
