You making a asynchronous network request inside closure and compiler doesn't wait for the response, so just Reload Table when get post data. replace the code with below it work works fine for you. All the best.

 func addDataToPostArray(){
        let databaseRef = Database.database().reference()
        databaseRef.child("Post").queryOrderedByKey().observe(.childAdded, with:  {
            snapshot in

            let snapshotValue = snapshot.value as? NSDictionary
            let price = snapshotValue?["price"] as! String
            let description = snapshotValue?["Description"] as! String
            // print(description)
            //  print(price)

            let postArr =  displayStruct(price: price, Description: description)
            self.myPost.append(postArr)
            print(self.myPost.count)
            print(self.myPost)
            self.tableView.reloadData()
       //if i print self.myPost.count i get the correct length

        })
    }
