RoundedRectangle(cornerRadius: 8, style: .continuous) .
foregroundColor(Color.init(red: 255, green: 245, blue: 158))My rounded rectangle is all white. Why can't I initiate a custom color? Whereas Color.red works perfectly fine?

I want to create ruby text for some Japanese kanji and I can get CTRubyAnnotationCreateWithAttributes to work with an attributed string inside a UILabel but not UITextView. Is there a way around this?

Hi, I am trying to use the natural language tagger for Japanese. I used this sample code:
var stringToRecognize = jpTextView.text
		let range = stringToRecognize!.startIndex ..< stringToRecognize!.endIndex
		let tagger = NLTagger(tagSchemes: [.lexicalClass])
		tagger.string = stringToRecognize
		tagger.enumerateTags(in: range, unit: .word, scheme: .lexicalClass) { (tag, range) -> Bool in
			print("Word [\(stringToRecognize![range])] : \(tag!.rawValue)")
			return true
		}
and applied it on some dummy data:
東京では１１月から、コロナウイルスの病気で入院する人が多くなっています。このため、お腹の中に赤ちゃんがいる看護師も仕事を続けています。家に小さな子どもがいる看護師は、子どもにウイルスがうつらないか心配しながら仕事をしています。
The output was:
Word [東京] : OtherWord
Word [で] : OtherWord
Word [は] : OtherWord
Word [１１] : OtherWord
Word [月] : OtherWord
Word [から] : OtherWord
Word [、] : Punctuation
Word [コロナ] : OtherWord

Word [この] : OtherWord

Word [の] : OtherWord
Word [中] : OtherWord
Word [に] : OtherWord

Word [に] : OtherWord
Word [小さな] : OtherWord
Word [子ども] : OtherWord
Word [が] : OtherWord
Word [いる] : OtherWord
Word [看護] : OtherWord
Word [師] : OtherWord
Word [は] : OtherWord
Word [、] : Punctuation
Word [子ども] : OtherWord
Word [に] : OtherWord
Word [ウイルス] : OtherWord
Word [が] : OtherWord
Word [うつら] : OtherWord
Word [ない] : OtherWord
Word [か] : OtherWord
Word [心配] : OtherWord
Word [し] : OtherWord
Word [ながら] : OtherWord
Word [仕事] : OtherWord
Word [を] : OtherWord
Word [し] : OtherWord
Word [て] : OtherWord
Word [い] : OtherWord
Word [ます] : OtherWord
Word [。] : SentenceTerminator
It looks like every word is just being picked up as OtherWord, and it can detect some punctuation. Is this correct, or will there be an improvement to the Japanese tagger soon so we can differentiate between nouns, verbs, conjunctions, particles, etc. ?

The Apple documentation gives some user interface design tips on modal sheets including renaming Cancel to something like Dismiss where relevant. But there's no guide whether this is possible in SwiftUI.
There's a link that takes you to setTitle for Watchkit: https://developer.apple.com/documentation/watchkit/wkinterfacecontroller/1619570-settitle
But is there something equivalent for SwiftUI on a Watch app?

Hi, I'm using one of the delegate methods to determine when words are about to be spoken and then trying to provide a color background to indicate what is about to be spoken:
func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, willSpeakRangeOfSpeechString characterRange: NSRange, utterance: AVSpeechUtterance) {
		guard let rangeInString = Range(characterRange, in: utterance.speechString) else { return }
		print("Will speak: \(utterance.speechString[rangeInString])")
		let attributes: [NSAttributedString.Key: Any] = [
			.foregroundColor: UIColor.darkText,
			.font: UIFont.systemFont(ofSize: 16)
		]
		let mutableAttributedString = NSMutableAttributedString(string: utterance.speechString, attributes: attributes)
		mutableAttributedString.addAttribute(.backgroundColor, value: UIColor.yellow, range: characterRange)
		jpTextView.attributedText = mutableAttributedString
	}
Based on the debug log I can see that it is reading every word in my UITextView, but when it comes to the yellow background highlighting, it's quite inconsistent and seems to skip around half the words. Is this an inherent issue related to the language I'm using (Japanese) or is there something fundamental in my code that needs to be fixed?

Hi, I spoke to someone during the audio lab today in relation to audio output of Chinese dialects. So I can now get cantonese and mandarin outputted. But now I'm trying to read the same line of text in both dialects, and the audio overlaps each other. What do I need to change in my code to create a pause between the two utterances rather than reading both at the same time?
let cantoUtterance = AVSpeechUtterance(string: chinese)
						//utterance.voice = AVSpeechSynthesisVoice(language: "zh-HK")
						cantoUtterance.voice = AVSpeechSynthesisVoice(identifier: "com.apple.ttsbundle.Sin-Ji-compact")
						// utterance.rate = 0.1
						let cantoSynthesizer = AVSpeechSynthesizer()
						cantoSynthesizer.speak(cantoUtterance)
						let mandoUtterance = AVSpeechUtterance(string: chinese)
						mandoUtterance.voice = AVSpeechSynthesisVoice(language: "zh-CN")
						let mandoSynthesizer = AVSpeechSynthesizer()
						mandoSynthesizer.speak(mandoUtterance)

Has anyone had any luck with RevenueCat and independent watchOS apps? I am having trouble retrieving SKProducts that i setup on app store connect. Is there something different about Watch apps that I need to factor in the configuration of RevenueCat. For example, when it asks for Bundle ID - which bundle ID do i input? My watch app has 3 bundle IDs for the app, the watch app, watchkit extension. There's no documentation out there, it's very confusing.

Hi, I did a watchOS lab today where I asked how to create a local notification (which repeats at a regular interval), but I want to change the text so that that the message is relevant "You currently have x number of words to revise".
I have setup the notification in my extension delegate as follows:
notificationCenter = UNUserNotificationCenter.current()
notificationCenter.removeAllPendingNotificationRequests()
let options: UNAuthorizationOptions = [.alert, .sound, .badge]
notificationCenter.requestAuthorization(options: options) {
(didAllow, error) in
if !didAllow {
print("User has declined notifications")
}
}
let content = UNMutableNotificationContent()
content.title = "Overdue cards"
content.body = "You have " + String(wordsOverdue) + " words to revise. "
content.sound = UNNotificationSound.default
content.userInfo = ["Overdue": database.getWordsOverdue()]
The Apple engineer suggested I add the last line as the variable number/content. Then he said to use the NotificationController where there is a didReceive method that is called when a notification comes in, and I can update my notification view.
The problem is, didReceive never gets called. When I test my app, it always just sends the original notification that I setup. What do I need to do for notification controller to know when a local notification has come in?
I'm open to alternative solutions, since I just have a single value that needs to be updated.

I've downloaded the new Xcode 11.4 update and it's broken my codebase. I use GeometryReader to determine the user's Watch screen size so it can draw a frame that fills up most of the frame.Say if I wrote this to draw a rectangular frame:var body: some View {
GeometryReader {geometry in
ZStack {
// Draw rounded rectangle flashcard background
RoundedRectangle(cornerRadius: 15, style: .continuous)
.frame(width: geometry.size.width, height: geometry.size.height*0.9)
}
}
}It looks fine at the moment. But my main view usually uses subviews more like this:var body: some View {
GeometryReader {geometry in
ZStack {
// Draw rounded rectangle flashcard background
Frontside(id: self.$settings.randomNum, sheet: self.$showingSheet, rotate: self.$fullRotation, invis: self.$showNextCard, col: self.$colour, width: geometry.size.width*0.9, height: geometry.size.height).environmentObject(self.settings)
.rotation3DEffect(.degrees(self.showResults ? 180.0 : 0.0), axis: (x: 0.0, y: 1.0, z: 0.0))
.rotation3DEffect(.degrees(self.fullRotation ? 360.0 : 0.0), axis: (x: 0.0, y: 1.0, z: 0.0))
.opacity(self.showResults ? 0 : 1)
.zIndex(self.showResults ? 0 : 1)
}
}
}public struct Frontside: View
{
@EnvironmentObject var settings: UserSettings
@Binding public var id: Int
@Binding public var sheet: Bool
@Binding public var rotate: Bool
@Binding public var invis: Bool
@Binding public var col: Int
public var width: CGFloat
public var height: CGFloat
public var body: some View
{
ZStack {
// Draw rounded rectangle flashcard background
RoundedRectangle(cornerRadius: 15, style: .continuous)
.frame(width: self.width, height: self.height)
.zIndex(0)
}
}
}For some reason this causes an error when I call Frontside. Does anyone know why? There doesn't seem to be a real difference between the two code snippets other than using a subview in the second example.

.actionSheet(isPresented: $showingExampleSentences) {
ActionSheet(title: Text("Example Sentence"), message: Text(sentence_foreign_language + "\n" + .sentence_english), buttons: [.default(Text("OK"))]);
}I've got a SwiftUI action sheet where it displays two lines of text, but by default they are centre-aligned. Is there a way to make it aligned to the top-left?

My app crashes as soon as I try to launch it from my Watch, even though it works completely fine in various simulators. How do I go about finding out what is causing it to crash?Note that I've had my app run on my watch before, but all the iOS/WatchOS/Catalina updates as late caused an issue where I couldn't install my app to my Watch. After the latest update I can still it to my watch again except it just crashes on startup.

I have just designed an icon in Sketch for a Watch app. In Xcode, it looks like I need to create 11 different sizes of this icon. What is the quickest way to do this? Is there an app/script that can import the icon I've created and creates the 11 different-sized icons? Thanks.

}After toggling daily reminder, I'd like to create a time picker for the user to select when the daily reminder/notification will occur. I thought something like DatePicker would suit my needs but then it said it is not supported in WatchOS. So what other alternatives are available? Thanks.

How do I save their selection?Also, what is the best way to save user selections beyond the current app session? Should I write all their selections to a plist file or is there a conventional way?

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.
