When my application finished being launched, there are supposed to be data displayed on UITableViewCell. However, there is nothing there, so after relaunch the app, by pressing home button and swiping up the view, and select my demo app, all data is shown up properly and there seems like nothing is wrong. What causes the initial problem? Do you have any ideas why?
Did you set the tableView.dataSource to self? Also, you need to call tableView.reloadData() for populating the datas. Hope this helps.
When you use UITableView, dont forget to call self.tableView.reloadData() after downloading data.

I wrote a program and after re-running it on the simulator, it now shows the home screen in black.
You have tried to adapt your project not to use scene delegates, but you did it wrong. Here are the things you need to do:
Make sure the Info.plist has no Application Scene Manifest entry.
Make sure the AppDelegate has no methods that mention scenes.
Make sure the AppDelegate has a window property.

I'm trying to build a chat app like the native Messages app/Whatsapp.
The design is a little bit different than the native chat bubbles (rectangle messages view instead of bubbles) but I guess the basics are the same. Of course the messages should start from the bottom of the screen like any chat app, and in the bottom there should be a "new message" textField.
Should I use UITableView or UICollectionView for this purpose?
Thank you!
I just finished shipping a chat app and went through this exact question when building the architecture. This isn't a hot take.
I made the mistake at first to go with UITableView only to realize halfway that UICollectionView is way more powerful. (UICollectionView even has a tableLayout if you want to use it this way).
I realized this after studying the other chat libraries available like JSQMessagesViewController, MMTextureChat, MessageKit etc.
UITableView is good but soon enough you'll run into performance and customization issues like I did.
As for showing the messages from the bottom, the trick is to flip the view. That way when you call insert(atIndexPath:) the item shows up at the bottom.
Hope it helps.

Repo for the same: https://github.com/tush4r/Phone
I have a little test application with no special features except some view elements, including field, button and so on. It is a separate storyboard module and gets called when the app is loaded.
Everything seems good here, till I push the app in the background by pressing the home button. Below are the screenshots for the same: One when the app is running, one after it went in the background and came back to the foreground.
I have no idea why is this happening? A couple of things implemented in the view controller are: Keyboard-hide on tap, UIButton, UITextField, and couple of alerts when the number entered is in the incorrect format.
Any help would be greatly appreciated.
Thank You!

Try definesPresentationContext to set true, works for me with similar problem.
In viewDidLoad(), add definesPresentationContext = true

You need to add elements in to your view controller in storyBoard manually and connect its outlet and actions.

What is the easiest way to clear cell.imageView.image when you are reusing table cells in cellForRowAtIndexPath? The problem is when I am scrolling table and new images start to load I can still see previous images for a couple of seconds.
Set placeholder image or nil to imageview.image.
