Problems saving and retrieving numbers - swift

Question

I am working on an app that uses CoreData.
I am strong numbers and retrieving them, but when i store more than one field it only shows the last field with the number but a 0 in all the others. below is my codes.
to store them...
let CWConvert = Double(CWeight.text!)
storeTranscription18CW(pageText: (CWConvert)!, textFileUrlString: "cWeight")
savePlus += 1
let TWConvert = Double(TWeight.text!)
storeTranscription18TW(pageText: (TWConvert)!, textFileUrlString: "tWeight")
and...
func getContext () -> NSManagedObjectContext {
_ = UIApplication.shared.delegate as! AppDelegate
return DataController().managedObjectContext
}
func storeTranscription18CW (pageText: Double, textFileUrlString: String) {
let context = getContext()
//retrieve the entity that we just created
let entity = NSEntityDescription.entity(forEntityName: "TextInputs", in: context)
let transc = NSManagedObject(entity: entity!, insertInto: context)
// set the entity values
transc.setValue(pageText, forKey: "cWeight")
//save the object
do {
try context.save()
print("saved!")
} catch let error as NSError {
print("Could not save \(error), \(error.userInfo)")
} catch {
}
}
func storeTranscription18TW (pageText: Double, textFileUrlString: String) {
let contexta = getContext()
//retrieve the entity that we just created
let entitya = NSEntityDescription.entity(forEntityName: "TextInputs", in: contexta)
let transc = NSManagedObject(entity: entitya!, insertInto: contexta)
// set the entity values
transc.setValue(pageText, forKey: "tWeight")
//save the object
do {
try contexta.save()
print("saved!")
} catch let error as NSError {
print("Could not save \(error), \(error.userInfo)")
} catch {
}
}
and to retrive.
func getTranscriptions18CW () {
//create a fetch request, telling it about the entity
let fetchRequesta: NSFetchRequest<TextInputs> = TextInputs.fetchRequest()
do {
//go get the results
let searchResults18CW = try getContext().fetch(fetchRequesta)
for transa in searchResults18CW as [NSManagedObject] {
if let resulta = transa.value(forKey: "cWeight") {
if let stra = resulta as? String {
CWeight.text = stra
}else {
CWeight?.text = "\(resulta)"
}
}
}
//get the Key Value pairs (although there may be a better
}catch {
print("Error with request: \(error)")
}
}
func getTranscriptions18TW () {
//create a fetch request, telling it about the entity
let fetchRequest: NSFetchRequest<TextInputs> = TextInputs.fetchRequest()
do {
//go get the results
let searchResults18TW = try getContext().fetch(fetchRequest)
for trans in searchResults18TW as [NSManagedObject] {
if let result = trans.value(forKey: "tWeight") {
if let str = result as? String {
TWeight.text = str
}else {
TWeight?.text = "\(result)"
}
}
//get the Key Value pairs (although there may be a better way to do that...
}
}catch {
print("Error with request: \(error)")
}
}
i have tried different names but get the same it only shows the last one as the real number if i moment out the last one then the first shows the real value.

Try something more like this to save so that you are saving both in the same row.
func storeTranscription18TW () {
let contexta = getContext()
//retrieve the entity that we just created
let entitya = NSEntityDescription.entity(forEntityName: "TextInputs", in: contexta)
let transc = NSManagedObject(entity: entitya!, insertInto: contexta)
// set the entity values
transc.setValue(CWConvert, forKey: "cWeight") // Note the change from pageText
transc.setValue(TWConvert, forKey: "tWeight") // Note the change from pageText
//save the object
do {
try contexta.save()
print("saved!")
} catch let error as NSError {
print("Could not save \(error), \(error.userInfo)")
} catch {
}
}
Then when you do a get they would both be done in the same function as well.
