On the Apple Watch, if you go to Settings -> Wake Screen and then scroll down to ON SCREEN RAISE SHOW LAST APP. Underneath it is a list/table where the items are grouped, the first and last items have a rounded rectangle whereas the items in the middle are just rectangles. I would like to use this UI element as well when I present the user a list that functions like a radio button list. Do you know what this UI element is called? Is it just a List but with a specific list style? Thanks.

I had a working Watch up until the recent Catalina update, which broke Xcode as it didn't have support files for iPhone 11. I updated to Xcode 11.2 and now it compiles my app but when it tries to install to my Series 3 watch I get this error:Details

public var body: some View
{
ZStack{
GeometryReader { geometry in
RoundedRectangle(cornerRadius: 25, style: .continuous)
.frame(width: geometry.size.width*1.00, height: geometry.size.height*1.00)
.zIndex(0)
}
}
}I'm using GeometryReader to draw a rounded rectangle to fill up the entire watch screen, this looks fine on a 38mm watch simulator, but as I increase the watch size to 40, 42, 44mm I noticed that the height is not filling up the whole screen. I have to adjust my multiple to say 1.1 for example to fill up more of the screen.Can someone tell me if I am using GeometryReader incorrectly?

.contextMenu(menuItems: {Button(action: {
tangoArray[randomNum].bookmark.toggle()
database.updateUserData(tango: tangoArray[randomNum])
self.fullRotation.toggle()
}, label: {
VStack{
Image(systemName: tangoArray[randomNum].bookmark ? "bookmark" : "bookmark.fill")
.font(.title)
Text(tangoArray[randomNum].bookmark ? "Remove bookmark" : "Bookmark")
}
})
})I'm trying to use a contextMenu to bookmark flashcard items. What I have found though is that even after randonNum has changed, so adifferent flashcard is presented, the bookmark in the context menu is still showing the previous card's status. For example, it's a filled bookmark if I just tagged the previous card as a bookmark.

}I have a view which is a flashcard. When the user taps on the incorrect button I want the flash card to slide to the left of the screen, and when the user taps on the correct button I want the flash card to transition/slide to the right of the watch screen. How do I do that?

.navigationBarTitle("Study")It defaults to a greyish colour, if I wanted to change the colour what do I need to add? Thanks.

Hi,What's the easiest way to create either a Rectangle or RoundedRectangle that will fill the entire area of the watch face? I don't want to just flood the whole screen in a colour, because I want to round the corners of my background rectangle which will be the bottom layer in my ZStack.I also want to make my app scalable across different watch sizes from 38mm to 44mm, hence I can't use maxWidth maxHeight. Is there a way to set percentage of the screen?

I've just updated to the latest Xcode 11 GM and it has broken my code. I have this HStack as follows:HStack {
Image(systemName: "rectangle.on.rectangle.angled")
Text(verbatim: "Study")
.listRowPlatterColor(Color.gray)
.frame(height:50)
}But in the latest version I am getting this error:Cannot convert value of type 'TupleView<(Image, some View)>' to closure result type '_'What do I need to do to make HStack comply with the latest syntax?

I have the following SwiftUI view:struct Flashcard : View {
@State var cardText = newArray[randomNum].kana
var body: some View {
let stack = VStack{
Text(cardText)
.color(.red)
.font(.title)
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: 200)
.tapAction {
self.flipCard()
}
HStack {
Button(action: {
print("button pressed")
self.incorrect()
}) {
Image(systemName: "xmark.circle")
.font(.title)
}
.opacity(0.4)
Button(action: {
print("button pressed")
self.correct()
}) {
Image(systemName: "checkmark.circle")
.font(.title)
}
.opacity(0.4)
}
}
//.background(Color.blue)
.cornerRadius(25)
return stack
}I'm trying to make the background colour of the VStack blue, but when I do that, I realise that the Buttons are no longer pressable. Is there a way to make them always on top? Should I be using a ZStack as well to make the Buttons the last view that is added to the stack? I tried using a ZStack but getting a lot of strange outcomes.

Hi,I believe NavigationView is not available on SwiftUI for the Watch. What would I use in its place? I have a menu list which I want to add enable each item to be pressed to move to another view.import SwiftUI
struct ContentView : View {
var body: some View {
List {
HStack {
Image(systemName: "rectangle.on.rectangle.angled")
Text("Study")
.listRowPlatterColor(Color.gray)
.frame(height:50)
}
HStack {
Image(systemName: "star.fill")
Text("Favourites")
.listRowPlatterColor(Color.gray)
.frame(height:50)
}
HStack {
Image(systemName: "gear")
Text("Settings")
.listRowPlatterColor(Color.gray)
.frame(height:50)
}
}
.listStyle(.carousel)
}Thanks.

Hi, I am building an app that has about 8,000 rows of data (file size is around 1MB). At the moment I am storing this all in a plist, but I read that I should keep plists below 200Kb. I also need to read and write this data, so it would be handy to use database functionality rather than serialising 8,000 rows for each operation.So does SQLite exist on the Apple Watch? How can I create an SQLite database-based app in Xcode? Thanks.
