Cast from FIRRemoteConfigValue to unrelated type String always fails : Firebase, Swift

Question

I know this is a duplicate of Cast from FIRRemoteConfigValue to unrelated type String always fails . But the accepted answer there is that it's just a bug .

Which i don't think it is.

According to another solution, I have to force-cast the datatype every time I retrieve or instantiate a variable. I was hoping to find a different and elegant solution to this.

Everything was working fine, but after I installed Pod 'FirebaseRemoteConfig' , I am having this warning on every line I instantiate a variable with a Snapshot value that I receive.

Cast from FIRRemoteConfigValue to unrelated type String always fails

When I run my app, it crashes there.

Bugged Code

FIRDatabase.database().reference().child("Posts").observe(.value, with: {(recievedSnap) in

            if recievedSnap.exists(){
                if let dict = recievedSnap.value as? [String:AnyObject]{
                    for each in dict{

                        let str = each.value["text"] as! String //Line of warning(and crash when the app is run)
                        } 
                }
            }
        })

Working Code

 FIRDatabase.database().reference().child("Posts").observe(.value, with: {(recievedSnap) in

            if recievedSnap.exists(){
                if let dict = recievedSnap.value as? [String:AnyObject]{
                    for each in dict{
                        if let eachValue = each.value as? [String:AnyObject]{
                        let str = eachValue["text"] as! String
                        } 
                    }
                }
            }
        })

I am looking for explanation as to:

• What changed after Pod 'FirebaseRemoteConfig' installation that it started giving me this error?

• Why am I required to force cast every time I initialize a variable?

• Is there a better approach?

Answer 1

Finally got the solution...

Use valueForKey Instead of [] bracket access value, because FIRRemoteConfigValue dont have support to access value using []

Then all value goes away...

For Example

Warning code...

Below code give a warning...

            let id = snapshot.value!["senderId"] as! String
            let text = snapshot.value!["text"] as! String
            let locationId = snapshot.value!["location"] as! String

Use Like this

                let id = snapshot.value.valueForKey("senderId") as! String
                let text = snapshot.value.valueForKey("text") as! String
                let locationId = snapshot.value.valueForKey("location") as! String

Warming is not appear longer.....

NOTE: If you use like above then old code also working fine...
