Swift UITableView - Insert and Delete Rows - Tutorial

I don’t understand what that random “VideoCell” type that comes after as! In the cellForRow, it fucks the entire code up!?

Clean code + great explanation = Amazing Tutorial


and also providing source code


Thank you dude, you are awesome.

I loved your vids
Can you make a vid of insert data from TextField into the array pls?

How to one button delete all rows?

Thanks Sean for the helpful video. Does data inserted to the table using this method persist? If so where is it stores? If not, how can we save the data permanently at the user device?

Wow I understands it very easily bro u nailed it ,can u make a video to add and delete from different sections like if I tap on whatsapp status from recent it is adding to viewed after watched that like this pls .thanku

@Sean could you please do a updating video cause of Apple's Documentation notice:
    // Allows multiple insert/delete/reload/move calls to be animated simultaneously. Nestable.
    @available(iOS 11.0, *)
    open func performBatchUpdates(_ updates: (() -> Void)?, completion: ((Bool) -> Void)? = nil

    // Use -performBatchUpdates:completion: instead of these methods below, which will be deprecated in a future release.
    open func beginUpdates(), ....

Hello What I am doing is select date + insert data into text field then press submit to be pushed into TableViewController to display in TableViewCell in Labels, the issue is I cannot figure out how to do that, so every time you pick the date and the data and press submit it must sort in the tableviewcontroller in new tableviewcell.

Hey Sean
I have a doubt what if we initially don't have any data in our array then will this work or is there anything else that we have to do..
Thanks in advance

Once again, great help

How to insert a row if I click on button directly to the tableview without any Textfield ?? Sir

when the like button isn't an option - thanks for the video

Hi Sean. Will this persist the addition or deletion of the row. Or do I need to implement CoreData to persist the updated tableview.

hey, I'm new at coding and I was wondering is it consider plagiarism if I enter that deleted line of code into an app that I want to build?

thank you

Excuse me, where can I see your source codes. I just a beginner.

So what about the content of VideoCell.swift???

(Insert Comment Here)

Excellent! Thanks.

What if you have the button INSIDE the cell. Would you need a delegate to use the textfield text in the button function (as the textfield is registered in the VC not in the cell) ? How would the button know what do you enter in the textfield ?

Are you using two separate View controllers. if yes then how are they connected to each other.

hi there, what does " let cell = tableView.dequeueReusableCell(withIdentifier: "VideoCell") as! VideoCell " mean
I am using the same code just changing the "VideoCell" with "ItemCell" at both places. I am getting a error saying "Use of undeclared type 'ItemCell' ".
please help. Thank you.

Beautiful tutorial Sean. just to point out am not sure if its an update in swift it self or not but the tableview.beginUpdates() code instead runs error: stating Out of index. but tableview.reloadData() work instead. 🙏🏿 keep it up Sean Allen.

Thanks for another great video, Sean. I have an issue with making it work though, if you delete several rows one after another it crashes with "Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'No occurrence for index path (null)'", googling shows that that's an issue on latest iOS, but I could not find a solution. Maybe you have some thoughts?

Once again you have you have clearly explained something I needed for a production app. Thank you.

How about swiping the row and having 2 options like "yes" or "no"?

Sean why not to teach on Udemy? I personally would by your course.

Could you also make a video about a download manager that downloads files from Internet and write them to the device for future uses?

Hi. Very helpful video but, on tableview.insertRows I get signal SIGABRT error. What should I do?

I have one doubt, you wrote the following code
let indexPath = IndexPath(row: videos.count - 1, section: 0)

tableView.beginUpdates()
tableView.insertRows(at: [indexPath], with: .automatic)
tableView.endUpdates()

in insertNewVideoTitle(), but you can replace it with just one line
tableView.reloadData()
Same thing in editing style of table view method.

Am I missing some point?

Hi Allen, how can we add the data to tableview and pass it to the next screen (segue).
Thanks a lot :)

Hi Sean,nice videos Can you do a video best way of calling web API in swift

Simple and clean, great video mate

Thank you, it's a great video! But in InsertRow(tableview.insertRows(at: [IndexPath(row: videolist.count - 1, section:0)], with: .automatic)) it crashed, leaving an error 'attempt to insert row 1 into section 0, but there are only 0 rows in section 0 after the update'. How could I fix it?

When (editingStyle == .insert) will run???

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
print("this is a ttetetetette")
timeLogs.remove(at: indexPath.row)
timeLogTable.beginUpdates()
timeLogTable.deleteRows(at: [indexPath], with: .automatic)
timeLogTable.endUpdates()
}
else if editingStyle == .insert
{

print("this is a i🤡")


}
}

Sean, I have a quick question. Do you know how to save the TableView data when the app is closed. I got my app to add and delete rows but, when I close the app the added rows are deleted. I've spent a lot of time scavenging the internet for an answer and I have not solved the problem. Could you possibly do a video on how to save the added cells? Thanks!

Please help. When the "add" button is clicked i get an error that says "0_pthread_kill". I compared your source code to my code and it is the same. I looked up the problem and people were saying its something with breakpoints but i can't figure out what to do.

Good training. Thank you Sean to make effort offering the video. One minor thing about the func insertNewVideoTitle(). Should this one be private?

PLS HELP ME , INSERTROW IS ONLY CRASHING

will the slide to right delete method work on Firebase based table view data ? tried many times give me error. anyone got luck?

Great tutorial.  Love the tip about keeping code clean and easy to read.  Thanks.

Thanks! I'd like to see this for adding a new row dynamically to a 2D array. For example, how to get an index path in the insertNewVideoTitle() when you're working with multiple sections.

You need to teach or a course or something! Make it look so simple!

Wouldn't tapping on the add button with no text entered crash your app since you are force unwrapping the addVideoTextField.text! ?

Love your videos! I am learning from you and from the Big Nerd Ranch iOS programming book. Highly recommended!

Thanks for Tutorial
Can you please let me know how to add data on tableView when textfield is in different viewController ?
