Retrieving Data from FireBase SWIFT

I'm trying to get data out of a firebase database if the addedByUser = a value stored in the application.

With what I currently have, nothing is appearing in the table.

The firebase database looks like this:

workout1 "name" "addedByUser"

My code looks like this:

workout3Ref.observeEventType(.Value, withBlock: { snapshot in
            var newWorkout = [Workout1Info]()
            for item in snapshot.children {
                let createdBy = snapshot.value["addedByUser"] as? String
                if createdBy == Username.sharedInstance.userDetail {
                    let workoutItem = Workout1Info(snapshot: item as! FDataSnapshot)
                    newWorkout.append(workoutItem)
                }
            }
            self.workouts = newWorkout
            self.tableView.reloadData()
        })

When I get data normally without comparing if the addedByUser it normally works. Does anyone know why it isn't working?

Thanks for the help

  • While you are comaparing String createdBy with Username.sharedInstance.userDetail check your property Username.sharedInstance.userDetail also should be of String type.

Here's my guess based on a super vague question with some coding issues:

The createdBy is the users name or uid as a string.

The Username.sharedInstance.userDetail is an object (of some kind)

So you are comparing a String to an object that isn't a string, and that won't work.

Also, if the node you are query-ing is the /workout1 node, then you should probably name your reference workout1Ref instead of workout3Ref. That may help keep things straight in code.
