Clarity is the signature of your videos as is your ability to find the perfect «SwiftUI way» of doing things. The ".onDelete" is a very efficient way to handle a quick deletion, but I wonder why no one has found a way to elegantly add an alert into this process when the consequence of the deletion is more important. This is not unusual and several Apple applications include this double confirmation. Thank you for your work; There's not a single video where I don't learn something really useful.

As someone who suffers strobing lights and these kind of "movements" I'm really struggling to follow (to the point of being phisically sick). In fact, I had to stop at 20 minutes in, a few hours ago, and I've only just come back to resume (but still really suffer and I'm not sure I can finish the video and the series). I'm still learning Swift with HWS and SwiftData is something I'm really intrigued by and I try to delve deeper at every occasion. Keep up the good work and I hope you could consider my suggestion. It would make more widespread and accessible. Cheers.

One problem I have had so far is that when I relied on the init in the Book class description to populate the optionals, the newBook call in the create button was unjhappy with the optional parameters so I had to define them there in the create code. Is there something wrong with the way I set up the Book init?

@johndoe276. It's even more complicated ... if the book.status is .onShelf, the .onChange method is never called during opening of the view, thus firstView is again not set to false. Manually setting firstView to false fixed this for me in the .onAppear method: if status == book.status { firstView = false } else { status = book.status } Pheeewww .. complicated one. Maybe making the @State variables optional would have avoided this. But would have introduced a lot of code dealing with the optionals then ... Stewart, what do you think? Thanks! Reply @tazman7689 @StewartLynch I experienced exactly the same behavior. First, I did my own code just following the video and I had that same strange behavior. Then I copied all the code given by Stewart as well, considering that maybe I had had some issue in my code, but the result was exactly the same even using the Stewart's code.

Very nice video and a great introduction to SwiftDate. Getting started seem too easy easy, but then the going gets tougher. DB Browser is a very nice app and a great addition to my helper apps. It seems that visualization is done on a db copy obtained by a query? Is that correct, or did I misunderstand? At least the modification is done on individual data then copied onto the table last minute after verification. Because SwiftData updates at once? Did I understand correctly?

@StewartLynch3 ай бұрын
The list down can't be a NavigationLink then because that will always push on to a navigation stack. If you want to use a sheet to edit, then if your sheet iterates through an array of those books then you can capture it in the button that you use to trigger the presentation of the view. I like to use the .sheet(item...) presentation where the item is some Optional identifiable object rather than based on a Boolean value. Then, I create an enum to use as the object and make sure it is identifiable and each case has an associated values so for example: (Warning: I am typing this freehand without code checking so there could be some typos here) enum SheetPresenter: Identifiable { case selectedBook(Book) var id: String { String(describing: self) } } Then in your view, you can have @State private var selectedBook: SelectedBook? When you tap on the book, if your iterator for the list is book, you can set selectedBook = .selectedBook(book() The sheet will be presented with .sheet(item: $selectedBook) { book in EditView(book: Book) }

One issue I seem to be having is that after I add a book and update its dateStarted value, then update, then edit the book again to change the status to completed the dateCompleted is initially set to Dec 31, 1 (i.e., in the very distant past). This happens even though I did make the change to add a range as in the video (which worked in the case of dateStarted). When I changed the initial value of dateCompleted to Date.now from Date.distantPast the problem went away and the picker starts at dateStarted as it is supposed to. Have you seen this issue?

Hey Stuart, this is awesome video, but I have a urgent question: I have a game object that has a location that is set up as optional. Can/should I make that non-optional? Do I have to make an explicit relationship or can I use the implicit version. If you’d like me to make a relationship, which object, the game, or the location would I choose to place the @relationship? (it would seem impossible to add it to the location, because there’s no ‘game’ listed there. in other words, locations don’t know about games, but games know about locations. (The game must have exactly one location no more. So there’s no arrays.) I’m setting up a new object with pickers from all the locations and then the use hits a CREATE button, and it inserts to the database. How can I avoid having nil assignments for location? I’m having a problem with records being inserted in the database with nil. Thanks so much. I love the channel. And if any of your readers can help me out. That would be amazing.
@StewartLynch Жыл бұрын
Where are the pickers getting the locations from? A locations table or are they hard coded? Instead of nil, you could have a ‘fake’ location like I do with date and make this the initial default. Your view could check to see if your object has fake location property and if so, present the picker where the first item in the picker is the fake location tag but the view says “Pick a Location”

General question with SwiftData: Is this set up correct? ----------------------------------------------------------- Game needs ONE location Locations can be assigned to many different games. @Model final class location { var id: UUID var text: String } @Model final class game { @Attribute(.unique) var id: UUID … var location: location? }
@StewartLynch Жыл бұрын
If locations can be assigned to many games, you have a one to many relationship from location to games so in location you will need a var games: [Game]?

@@StewartLynch Thanks! I'm still confused though. By having var location: location? (inside game class), doesn't this create an implicit relationship both ways? My app runs w/o errors. What am I missing?

@@chezchezchezchez I am confused by what you are saying, Probably best to continue this conversation via email as it is off topic for this video. I cover relationships in subsequent videos in this series

Hi Great video and I'll be watching the series. Just one little thing not sure if its a bug but when you change the status of a book to completed the date picker stays in the distant past and it never updates to the current date unless you manually change it in the picker itself. It does the same behaviour in the competed app from GitHub as well. the date stays at Dec 31, 1 like the year 2001 I think. Is anybody else getting this or am I just thinking about this wrong?

What if you go from onShelf to inProgress then Completed? My code may not be perfect, but the SwiftData stuff is still good. See if you can improve the code and share.

@@StewartLynch Yep it does the same thing, just for some reason it refuses to update the dateCompleted property until you use the picker. Ive tried rewriting it as a switch rather then If then else statements (no luck) one thing that does make it behave a little bit more constantly is changing the Datepicker for dateCompleted to this: DatePicker("", selection: $dateCompleted, in: dateAdded...Date.now, displayedComponents: .date) that at least should give a date that's closer to what somebody would want and not constantly setting itself to the distant past that's the best solution I have for now.

Hi Stweart, big thanks from beginner developer. Great free content. Can anyone explaine to me, how and when firstView change state from true to false? Because in this example never get into this block of code. It's always true .onChange(of: status) { oldValue, newValue in if !firstView { if newValue == .onShelf { dateStarted = Date.distantPast dateComplited = Date.distantPast } else if newValue == .inProgress && oldValue == .completed { // from completed to inProgress dateComplited = Date.distantPast } else if newValue == .inProgress && oldValue == .onShelf { // book has been started dateStarted = Date.now } else if newValue == .completed && oldValue == .onShelf { // forgot to start book dateComplited = Date.now dateStarted = dateAdded } else { // completed dateComplited = Date.now } firstView = false } }

HI Stewart. On the Edit/Update I'm trying to pass an Int? into a Picker as below. If I put gidata.growthYears in a Textfield it shows up fine but when I try to add it to my Picker the Picker show up but nothing is selected as default nor can I select anything. Any tips or suggestions let gidata: myModel @State private var yrsSelectedArray: [Int] = [1, 5, 10] Picker("Years for Simulation:", selection: .constant(gidata.growthYears)) { ForEach(yrsSelectedArray, id: \.self) { Text(String($0)) }
@StewartLynch8 ай бұрын
Looks like you are missing a .tag for your Text in the picker. So Text(Sttring($0)).tag($0)

Found no comparable tutorial about Swift Data with the possibility of editing the data after storage. I am excited.@@StewartLynch
