Zong | Zong !

I need your help with how to solve my custom data slow loading. I create a collection of my native song lyrics as data. Unexpectedly, there are over 500 songs, and when I try to load in my app, it is crazily slow. It took about over 5 minutes to display my lyric. Please help me with how do I solve it. I read about background threading, but I don't know it is related to my problem since I am not downloading any data. Especially, the slow loading significantly begins when the songs are over 150, and all the songs are hardcoded by me. Below is my code and thank you in advance. New update: Now, my Xcode stuck at Indexing | Processing files and asked me to Force Quit Xcode Application. This is my original Lyric file. Feel free to test it. https://github.com/siantung/Hymn-iOS

I am storing data in the real-time database, so for that, I am using the date as a child and if more than 1-time seizure has occurred then it will store the data with the new key under the same date, but let say if a seizure occurs tomorrow as well with date 3-6-2021, then how will it store the value with a new date?

Currently, data is storing like this:

How can I store data with the new date under the same child as Seizure_history?

My code looks like this:

I want to scrap ticker symbol from the table and check for if certain keywords are present{"GD","Daily price"," TSI"} in the "final settlement price" row. In the table, there are multiple dynamic columns.

Here is the HTML code for the ticker symbol row:
