This is a strange one, on one of my swift projects the code runs fine. On another it does not. I am testing out retrieving data with backendless as I begin to rewrite some code from Parse. It seems to be with the format the data is coming back in from the datastore.
var backendless = Backendless.sharedInstance()
let whereClause = "VoucherID = " + voucherID
let dataQuery = BackendlessDataQuery()
dataQuery.whereClause = whereClause
var error: Fault?
let datastore = backendless.data.of(Voucher.ofClass()).find(dataQuery, fault: &error)
if error == nil {
print("Vouchers have been found: \(datastore.data)")
let vouchers = datastore.data
for voucher in vouchers! as! [Voucher] {
print("\(voucher)")
}
}
else {
print("Server reported an error: \(error)")
}
OK fairly basic stuff. The project which works gives me output like this. voucher is the correct class. I have defined Voucher class in a swift file outside of the view controller. This all works perfectly.
Vouchers have been found: [<voucher.Voucher: 0x13773dd20>]
<voucher.Voucher: 0x13773dd20>
However the project throwing the error is giving me data in this format… This is the same output from exactly the same code…
Vouchers have been found: [{
AD1 = "";
AD2 = "";
AD3 = "";
AD4 = Kent;
AD5 = "<null>";
BookingDate = "29/02/2016";
BookingTime = "18 : 34";
Email = "";
FirstName = Michael;
Init = Michael;
PartyOptions = "|Players,5";
PartyTotal = "";
PartyType = "";
PostCode = "";
Redeemed = FALSE;
Surname = Turner;
Tel = 044;
Title = MR;
Valid = TRUE;
VoucherID = 92;
"___class" = Voucher;
"__meta" = "{\"relationRemovalIds\":{},\"selectedProperties\":[\"BookingDate\",\"Redeemed\",\"Email\",\"ownerId\",\"Init\",\"PartyTotal\",\"VoucherID\",\"___class\",\"PartyType\",\"objectId\",\"FirstName\",\"created\",\"BookingTime\",\"Title\",\"AD1\",\"AD2\",\"AD3\",\"AD4\",\"AD5\",\"Valid\",\"PartyOptions\",\"Tel\",\"PostCode\",\"updated\",\"Surname\"],\"relatedObjects\":{}}";
created = "2016-02-29 18:34:16 +0000";
objectId = "8A09BAAB-FB3C-7F12-FF3D-C6E8C3A88700";
ownerId = "<null>";
updated = "<null>";
}]
fatal error: NSArray element failed to match the Swift Array Element type
I am using exactly the same code, and have set the projects up to use Backendless in the same way, but for some reason something is very different. I have been on this all day so I hope you can help. It seems to be the data is coming through in a completely different format on one project compared to the other? I have followed other threads regarding NSArray element failed to match the Swift Array Element to no avail. Please help, been on this all day and I just can’t solve it!
