QUESTION
I have a list with a .searchable search bar on top of it. It filters a struct that has text, but also a date.
I'm trying to have the user select whether he/she wants to search for all items containing the specific text, or search for all items with a data. I thought the way that iOS Mail did it when you hit he search bar on top is a good way (I'm open to other options tho...).
It looks like this:
So, when you tap the search field, the picker, or two buttons, or a tab selector shows up. I can't quite figure which is it. Regardless, I tried with a picker, but:
- I don't know where to place it
- I don't know how to keep it hidden until needed, and then hide it again.
this is the basic code:

I have a picker that updates an variable bmr. the picker in not updating the value. I put a test Text on the second screen to see if I can call the new value, its always showing the default.

QUESTION
I am currently learning how to ask the user for an AppStore rating in the app. I have read through numerous documentations and reports from Apple and other bloggers, but I still have questions:
- I thought that I want to display my request after the user has completed a sequence of actions 3 times. But if the user doesn't want to rate my app right now, can I ask him to rate my app again later? I also read that Apple controls when and how often the review request is displayed (up to 3x / year)
- My app has different functions. Therefore it is not guaranteed that the user accesses exactly this function, where I want to show the rating view. Is it therefore possible to call up the rating request at different points in the app and simply leave it up to Apple whether the rating request is also displayed?
Best regards
Edit for @K bakalov :
...ANSWER
Answered 2022-Mar-19 at 11:06I assume you already read that but if you haven't I am leaving a link for you to check it out: https://developer.apple.com/documentation/storekit/requesting_app_store_reviews
It contains helpful information and guides when and how to prompt the user to leave a review.
Back to your questions.
-
- Yes, you can ask again for review but there is no guarantee that the Review pop-up (alert) will be presented again. It is usually delayed in time and sometimes requires a new update of the app to trigger a new review prompt; That is correct, Apple has control over it but I don't know if its limited to only 3 times a year.
-
- Yes, you can call it as many times as you want and wherever you find it suitable. Although, I highly encourage you to read (if still haven't) the link above. You need to think of a non-intrusive way to ask for review, otherwise you risk the user to dismiss the prompt, even if they like the app.
Just an advice, many apps use an approach with a custom popup "Do you like the app? Yes/No", if "Yes" then request a review using requestReview() call. And/or as mentioned in the article above, you can always use a manual review by redirecting to the AppStore, if you need it as a result of a CTA (tap on a button for example).

QUESTION
I'm really struggling to understand how the List(selection:) causes an update to the selection binding.
I am unpicking the Apple sample code at https://developer.apple.com/documentation/swiftui/building_a_great_mac_app_with_swiftui
The project is Session2/Part2-End/GardenApp.xcodeproj
There is a sidebar on the left, and the main detail view on the right. The ContentView looks like this:
ANSWER
Answered 2022-Mar-12 at 08:49You can find more details in the documentation for List, check out the example under "Supporting Multi-Dimensional Lists".
But basically, this is what is happening:
The line
List(selection: $selection)stores the selected garden in theselectionvariable of theSideBar.The
selectionvariable ofSideBaris a binding from theselectionvariable inContentView(see lineSidebar(selection: selection)), so when the former changes, the latter is updated too.The
selectedGardenvariable ofContentViewis a computed property that returns the garden at the index ofselection.wrappedValue- ifselection's value changes, theselectedGardenreturns a different value.The
GardenDetailview shows the details according to theselectedGardenvariable that is passed to it:GardenDetail(garden: selectedGarden).
Changing the selection in SideBar changes also the selection in ContenView, which makes the selectedGarden return a different garden which updates the GardenDetail view.
QUESTION
I'm building a macOS app where I have an observable Formatter object that uses @AppStorage to store the significant digit settings (see Formatter.swift). The number formatter is passed to the other views as an environment object using the main app struct MyApp.swift. In the preferences window SettingsView.swift, the significant digits are adjusted using steppers. Finally, the number formatter is assigned to text fields in ContentView.swift to format the input.
The problem is the text fields in the content view do not automatically update their format when the significant digits are changed in the settings view. The text labels automatically update because they read the app storage values directly. But the text fields are not observing the change to the number formatter. If I change the settings, restart the app, then the text fields will properly show the updated format. But how do I tell the text field to update when the formatter significant digits change?
Formatter.swift ...ANSWER
Answered 2022-Mar-12 at 08:29Add an .id to the TextFields, that will force a redraw on change:
QUESTION
I have an app with four (4) views, on the first view I'm showing a list of cars pulled from CoreData, the second view is presented when a car is tapped and it shows the services for each car. The third view is presented when tapping on a service, and it shows the details of the selected service. The fourth view is presented when tapping a button and it shows records for the specified service.
The issue I'm having is that for some reason if I use an @AppStorage property wrapper within the ServicesView I cannot dismiss the fourth view (RecordsView). I don't think the issue is with CoreData but let me know if you need to see the code for Core Data.
Any idea why adding an @AppStorage property wrapper in the ServicesView would affect other views?
CarsView ...ANSWER
Answered 2022-Mar-11 at 17:44NavigationView can only push one detail screen unless you set .isDetailLink(false) on the NavigationLink.
FYI we don't use view model objects in SwiftUI, you have to learn to use the View struct correctly along with @State, @Binding, @FetchRequest etc. that make the safe and efficient struct behave like an object. If you ignore this and use an object you'll experience the bugs that Swift with its value types was designed to prevent. For more info see this answer MVVM has no place in SwiftUI.
