Add, edit, move, and delete items in a List in SwiftUI | Bootcamp #31

In this video we will dive into the List component in SwiftUI. The List has built-in features that allow us to easily edit, move, add, and/or delete items from our data array. As you'll see, the list makes it incredibly simple to add a swipe-to-delete feature to our iOS application! We will also look into the different ways that we can customize the List with .listStyle().

And for the NavigationBarItems that are now deprecated, we should be using toolbar:
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
EditButton()
}
ToolbarItem(placement: .navigationBarTrailing) {
addButton
}
}

iOS 17.5
To get the sections to collapse you have declare a Boolean variable (e.g.

@State var isExpanded:Bool=true

)
, and then add an initializer of isExpanded to the Section(e.g.

Section(isExpanded: $isExpanded) then all the other stuff

). Bind the initializer to your Boolean and add the .listStyle(.sidebar) modifier to your List. Chevron is back!

As I want to mention, on the latest version of Xcode. We should add a () after the style, for example : .listStyle(GroupedListStyle) should be change to . Others listStyle as well.

Never knew about eliminating those variables in the move and delete calls. Very clean! Many new things here and I have used lists (and fought formatting them) in so many projects! Thanks Nick!

I suggest to show at the beginning what you will demonstrate in video demo, it would be amazing .

Nick,
THANKYOU, Another very nice lesson, very very useful,
#1 Section header does not show the Shevron icon, or even the color is not blue, may be new iOS the attributes are different?
(I tried iPhone, iPad etc, no luck), may be something I am doing wrong !
>>
Section(
header: Text("Fruits")) {
ForEach(fruits, id: \.self) {fruit in
Text(fruit.capitalized)
}
#2 also the styles does not change ... for example

Thank you - just brilliant and has helped me even more than CodingWithChris, which is a little disloyal, but he didn't get me where I needed to be for my current project challenge

tip regarding embedding in a view which is not in the suggestion list: choose the "Embed..." option which will automatically allow you to type the view in which you want to embed something.

You content is very good; if not excellent. Keep up the good work; looking forward to seeing more. However a small point...indices, plural of index, are not pronounced "in dices". They are pronounced(phonetically).... "in dih seas". Many words that end in "x" are similar...such as matrix.

A very very helpful tutorial, I am getting trough all tutorial videos, your SwiftUI Bootcamp is totally helpful!! Thank you for posting.

[Baxishoff]

Thanks for the great content, Nick. Learning a lot from your vids. I have the below questions:

1. swiftUI is not giving the collapsable list by default anymore. Looks like there is an extra step I have to take but not sure what it is.

2. Most important one. I have the code correct. I am able to add, edit and stuff. The only thing, when I move/reorder items in the list, they resist and get back to their own place. Any thoughts on that one?

Thanks a lot in advance.
