Firebase Can Read, But I'm Not Able To Post - firebase

Question

App I've created is able to read data from firebase no problem. However, when I try to write data to it, doesn't seem to be working. I checked my rules to make sure ".write" was set to true, still not seeing anything pop up.
Trying to write an event to firebase as follows: ref?.child(email).child("events").setValue("Test")
Email variable has a value, though to double check it wasn't something weird with it I even tried substituting email for "test". Have no idea where else I could be going wrong, any help is a godsend!

Thank you so much in advance:

Breaking things down to minimal code can often help in troubleshooting. For example, try this
#class xxxx
var ref: DatabaseReference!
override func viewDidLoad() {
super.viewDidLoad()
ref = Database.database().reference()
ref.child("events").setValue("test")
}
Which will result in a Firebase like this
root_ref
events: "test"
It's also a good idea to include closures in your Firebase calls so you can catch any errors... so instead of setValue, you could use setValue with it's completion block (closure in swift)
let eventsRef = self.ref.child("events")
eventsRef.setValue("test", withCompletionBlock: { error in
if error != nil {
print(error)
}
})
