DataSnapshot.value is Any and according to the documentation you could cast it in different types.

Data types returned: + NSDictionary + NSArray + NSNumber (also includes booleans) + NSString

If I understood your snipped well, in you case, you need to cast "DataSnapshot" into a dictionary in order to access with a subscript. You can try this:

databaseRef.child("ServiceA").queryOrderedByKey().observe(.childAdded, with: {
                DataSnapshot in
    let title = (snapshot.value as? [String: Any])?["title"] as? String
    self.posts.insert(PostStruct.init(title: title), at: 0)
})

Please also note that, in order to prevent crashes, I removed the force-wrap so "title" would be an optional String.
