I'm seeing unexpected behavior with the SwiftUI Toolbar. This code works but the items are grouped together in the center of the toolbar (as expected). However, if I add the two Spacers everything disappears.              ToolbarItem(placement: .bottomBar) {               HStack {                 Button(Constants.Buttons.Location) {                   print("button")                 }                 //Spacer()                 Image(systemName: Constants.Icons.Share)                 //Spacer()                 Button(Constants.Buttons.Website) {                   print("button")                 }               }             } If I add them all individually (including the two Spacers) I get the result I was expecting.        ToolbarItem(placement: .bottomBar) {         Button(Constants.Buttons.Location) {           print("button")         }       }       ToolbarItem(placement: .bottomBar) {         Spacer()       }       ToolbarItem(placement: .bottomBar) {         Image(systemName: Constants.Icons.Share)       }       ToolbarItem(placement: .bottomBar) {         Spacer()       }       ToolbarItem(placement: .bottomBar) {         Button(Constants.Buttons.Website) {           print("button")         }       }

I was seeing some behavior I couldn't understand with onAppear and my tabs (Xcode 12 beta 3). I wrote a quick project with two tabs to test. Here's tab1 (tab2 is the same).    var body: some View {     NavigationView {     Text("Tab1")     }     .onAppear() {       let datefor = DateFormatter()       datefor.timeStyle = .medium       print("onAppear tab1 \(datefor.string(from: Date()))")     }     .onDisappear() {       print("onDisappear tab1")     }   } At app launch: onAppear tab1 10:29:18 AM onAppear tab2 10:29:18 AM Touch tab2: onDisappear tab1 onDisappear tab2 onAppear tab2 10:29:42 AM onAppear tab1 10:29:42 AM Now this is where it gets interesting. Touch tab1 and the wrong onAppear gets called: onDisappear tab2 onAppear tab2 10:30:10 AM Touch tab2 and the same thing happens: onDisappear tab1 onAppear tab1 10:30:46 AM

Version 14.0 beta 4 (14A5284g) This is all referring to the simulator. When I run the Shortcuts app my phrase is properly shown for my app and the app's name is correctly populated. However, when I try to add a SiriTipView the same phrase shows the application name as ${APPLICATIONNAME}. I changed the first letter of the phrase and verified the change showed up in the Shortcuts app and my app tip. I'm not sure if I'm doing something wrong or should file feedback instead.

I'm using UICalendarView in my SwiftUI app. Inside of my func calendarView() I'm specifying emojis for decorations for certain days and they're showing up just fine. The problem is that VoiceOver completely ignores the decorations. If I touch a day it says the date and "button", which is exactly what I want. I've tried adding all of the accessibility items below but none of them cause VoiceOver to mention the day's decoration.        return .customView {         let emoji = UILabel()         emoji.text = foundEvent.emoji         emoji.isAccessibilityElement = true         emoji.accessibilityIdentifier = "identifier"         emoji.accessibilityTraits = .staticText         emoji.accessibilityLabel = "I like turtles."         emoji.accessibilityValue = foundEvent.emoji         emoji.accessibilityHint = "I also like turtles."         return emoji       }

Hello. I took a closer look at the data I'm getting back for hourly forecasts and I'm baffled by results I'm seeing. For example, it's Dec 19, 2022 8:00am PT and I'm asking for the weather for Orchard Park NY (lat 42.766437 long -78.743855) for Dec 23, 2022. The daily forecast tells me they're expected to have 5.9" of snow. However, the hourly forecast with the most snow that day is reported as 0.071" (1.8mm). The Apple Weather app on iOS shows that hour as having 0.6". I wrote a 'for' loop to print the results of my call to WeatherService.shared.weather.         print(oneHour.precipitationAmount.formatted())         print(oneHour.precipitationAmount.description)         print(oneHour.precipitationAmount.unit)         print(oneHour.precipitationAmount.value) 0.071 in 1.8 mm <_NSStatic_NSUnitLength: 0x2010b0178> mm 1.8

Hello. I noticed pretty early on that WeatherService.shared.weather seems to cache results. I realized this when I called it, killed network connectivity to my device, and then called it again I still got results back. My concern is about my widgets, which are also able to call WeatherService.shared.weather. I put my call inside of getTimeline(). After adding logging I realized that getTimeline() is called multiple times at the same time. For example, if I have two different widgets each with three different sizes (small, large, rectangular, etc) then six calls to getTimeline() are made for an update. I found a blog by Shopify iOS developers that describes how they found the same thing, but the forums aren't letting me link to their website's blog. My questions is which of these scenarios is happening: Even though WeatherService.shared.weather is called six times in the same second it's actually only the first call that goes out via the network and the remaining five calls just returned cached results. More than one of the six calls in the same second could be making a network call. If that's the case I'm going to need to add some form of throttling/caching because the number of free API calls per month is limited. Thank you!

My SwiftUI weather app shows weather stats for the day that I'm pulling from DayWeather. I added wind speed to my app recently. I wanted to add Gusts but I hit a problem. Whenever I look at the results returned for DayWeather the "gust" inside of Wind is always nil. The iOS weather app includes gusts in a daily summary. For example, today for ****** River, OR it says "Wind is currently 15 mph from the southeast. Today, wind speeds are 8 to 26 mph, with gusts up to 50 mph." A query I just did to WeatherKit returned 18mph with compass direction SSE but nil for gusts. I've searched the documentation and I can't determine if this is working as designed or a bug.

Hello. I've seen some other posts about NavigationStack, but my variation seems a little different. FYI, I have not migrated from ObservableObject to Observable yet. However, having a path in either seems to be a factor in this issue. My code has no issues when built with Xcode 15. When built with Xcode 16 I keep hitting scenarios where the .onAppear for my first tab gets called over and over again endlessly. If I go to my second tab, which uses a NavStack with a path and then navigate anywhere my .onAppear for my FIRST tab gets call endlessly. I’ll sometimes see a “double push” to the stack. (Someone posted a video of this happening on Mastodon, which apparently I’m not allowed to link to here.) The second tab is accessing the path property via an @EnvironmentObject. I can stop this endless loop by removing @Published from the property in my ObservableObject that holds my path. But then if I go to my third tab, which does NOT use a path, the .onAppear for my FIRST tab again gets called endlessly. So far on Mastodon I’ve seen three people encountering problems possibly related to storing a path in something being observed. Feedback requires a sample project, which I am having trouble creating to show the problem.

I added gesture support to my app that supports iOS 16 and 17 and have never had issues with it. However, when I compiled my app with Xcode 16 I immediately noticed a problem with the app when I ran it in the simulator. I couldn't scroll up or down. I figured out it’s because of my gesture support. My gesture support is pretty simple. let myDragGesture = DragGesture() .onChanged { gesture in self.offset = gesture.translation } .onEnded { _ in if self.offset.width > threshold { ...some logic } else if self.offset.width < -threshold { ...some other logic } logitUI.debug("drag gesture width was \(self.offset.width)") self.offset = .zero } If I pass nil to .gesture instead of myDragGesture then scrolling starts working again. Here’s some example output when I’m trying to scroll down. These messages do NOT appear when I run my app on an iOS 16/17 simulator with Xcode 15. drag gesture width was 5.333328 drag gesture width was -15.333344 drag gesture width was -3.000000 drag gesture width was -24.333328 drag gesture width was -30.666656 I opened FB14205678 about this.

We pass a CLLocation to the new WeatherService monthlyStatistics() BUT in the returned metadata the CLLocation data does NOT match what we sent in the request. For example, send lat -27.1480114 long -109.4273371 in the monthly stat request and get back data for lat -27.148000717163086, long -109.427001953125. There’s no mention in the documentation of the returned location being “close to” the requested location. If this is working as designed how close are the results allowed to be? In my small sample they seem to be around 45-55 meters away. I’m considering less than 100 meters away to be a match, but don’t know if that’s correct.

A year ago I filed feedback FB13055082 about this and I just realized that it was marked as "works as currently designed". I need help understanding why this is the expected behavior. For the feedback example I used Nepal, which is +5:45 from GMT. When the UTC offset is not at an hour interval, the dates returned by DayWeather and HourWeather do not match. I’ll request weather with a start date of Aug 25 at 12:0:0 AM GMT+5:45 and end date of Sep 3 at 12:0:0 AM GMT+5:45. The first daily forecast returns a date of Aug 25, 2023 at 12:0:0 AM GMT+5:45, which is what I expect. It's midnight in Nepal and the start of the day. If in my code I call (correct calendar).startOfDay(for: ) I'll also get this same time back. However, the first hourly forecast returned is for Aug 25, 2023 at 12:45:0 AM GMT+5:45 which is NOT the start of the day in Nepal or the start I asked for. It is 45 minutes off. How is the hourly data not starting at the time I requested the expected behavior? Especially when the day data does start at the time I requested.

Hello, is there any rough timeframe of when we can expect MonthPrecipitationStatistics to be fully populated with WeatherKit? averagePrecipitationAmount is being returned. averagePrecipitationProbability and averageSnowfallAmount are not and are always zero. I did file FB14326506 about this.

One of my blind users reached out to me after they updated to iPadOS 18. I have a button that is used to mark/unmark a favorite location. He said that he could still tell the favorite status via the label and hint, but VoiceOver was always saying that the switch button is off. I'm able to recreate this on my iPad as well. The documentation for .isToggle is completely blank. Basically with iPadOS 17 adding the .isToggle trait makes VoiceOver state that my button is a toggle. With iPadOS 18 adding the .isToggle trait makes VoiceOver state that my button is a toggle AND try to state its current value. I don't know if this is intentional or a bug. Button { showFavActions() } label: { Image(systemName: SFSymbolShortcut.star.rawValue) .symbolVariant(weatherData.currentlyFavIndex == nil ? .none : .fill) } .buttonStyle(.plain) .accessibilityLabel(Text(weatherData.currentlyFavIndex == nil ? "Not a favorite location." : "Favorite location.")) .accessibilityHint(Text(weatherData.currentlyFavIndex == nil ? "Add to favorites." : "Remove from favorites.")) .accessibilityInputLabels(["Favorite"]) .accessibilityAddTraits(.isToggle) // iOS 17

When a widget is using the new tinted mode in iOS 18 the Weather app shows the SF Symbols in both white and the tint color. For example, a tinted sun with a white arrow for sunrise. I can't figure out how to do this. If I add widgetAccentable to the Image(systemName:) the entire Image becomes the tint color. If I don't use it no combination of rendering mode or foreground style makes the tint color appear. I can't find any mention of this in the WWDC sessions.

I can't figure out if I've found a VoiceOver problem with Swift Charts or if I'm doing something incorrectly. I have a loop within a loop showing 2 sets of data in the same chart. If I touch a month then VO correctly says there are two data series. But if I keep swiping down only data from the first series is read. ChatGPT said try referencing the outer loop and sure enough that worked if it done in BOTH the label and value. It sounds really awkward though. For example, "High 89 degrees F High October". Below the "bad" chart only says something such as "92 degrees F October" when swiping down. The "good" chart will read the high and low temperature data. VStack { headerText("BAD") Chart { ForEach(processedMonthlyInput) { oneMonth in ForEach(oneMonth.temperatures, id: \.month) { element in LineMark( x: .value("Month", element.month, unit: .month), y: .value("Temperature", element.tempVal.converted(to: .fahrenheit).value) ) .accessibilityLabel("\(element.month.formatted(.dateTime.month(.wide)))") .accessibilityValue(Text("\(element.tempVal.converted(to: tempUnit).formatted(.measurement(width: .abbreviated, numberFormatStyle: .number.precision(.fractionLength(0)))))")) } .symbol(by: .value("Type", oneMonth.theType)) .foregroundStyle(by: .value("Type", oneMonth.theType)) .interpolationMethod(.catmullRom) } } .frame(maxHeight: paddingAmount) .padding(.horizontal) headerText("GOOD") Chart { ForEach(processedMonthlyInput) { oneMonth in ForEach(oneMonth.temperatures, id: \.month) { element in LineMark( x: .value("Month", element.month, unit: .month), y: .value("Temperature", element.tempVal.converted(to: .fahrenheit).value) ) .accessibilityLabel("\(oneMonth.theType) \(element.month.formatted(.dateTime.month(.wide)))") .accessibilityValue(Text("\(oneMonth.theType) \(element.tempVal.converted(to: tempUnit).formatted(.measurement(width: .abbreviated, numberFormatStyle: .number.precision(.fractionLength(0)))))")) } .symbol(by: .value("Type", oneMonth.theType)) .foregroundStyle(by: .value("Type", oneMonth.theType)) .interpolationMethod(.catmullRom) } } .frame(maxHeight: paddingAmount) .padding(.horizontal) }
