Subject: Enumerator using generic. Cleaner for .. in .. loop in Swift (#433)

* Enumerator using generic. Cleaner for .. in .. loop in Swift

So
for childSnapshot in snapshot.children {
you don't need to cast each child. Each cild is already known as DataSnapshot

* Update FIRDataSnapshot.h

* Update FIRMutableData.h

* Update FIRMutableData.m
