Hello, I would like to detect when the app is task killed (i.e. removed from background). I thought "applicationWillTerminate" is called at that time, but not called. How can I detect if the app is deleted from background. Thanks for your help in advance.

We've been using our app for the past year, and a user came back today that after three minutes, their phone starts getting hot and the screen dims. He is using 17.6.1 with an iPhone 14 max. No one else is seeing an issue, but with the posts online about 17.6.1 battery drain, I wonder if our AR app is somehow more sensitive to the issue.

Hello, I noticed a small mistake in the Human Interface Guidelines (HIG). On the page HIG > Components > System Experiences > Widget > watchOS Widget Dimensions, scroll down to the bottom. In the "watchOS widget dimensions" section, the sizes in the table are in pixels (px), not points (pt) actually. However, the table header indicates the sizes should be in points (pt). Page link: https://developer.apple.com/design/human-interface-guidelines/widgets#watchOS-widget-dimensions For example, the widget size in the Smart Stack on a 49mm watch should be 192x81.5 pt (or 382x163 px), not 382x163 pt. This size can be verified with the information provided here: https://developer.apple.com/documentation/watchos-apps/supporting-multiple-watch-sizes/. https://developer.apple.com/documentation/watchkit/wkinterfacedevice/1620974-screenscale

1) The situation: 8-bit grayscale still radiology-images, comparing to cheapest PC-displays: = appear "literally disgusting" on MacBook|M3; = appear "very bad" on iPAD|M2; = appear "just bad" on available iMAC (though this situation is ~correctable). Typical example (photo of 3 displays; the same 8-bit BMP or PNG by default view/preview on MacBook, iPAD, Windows): "https://ic.pics.livejournal.com/jbstphr/26474885/18157/18157_original.jpg" ** 2) The problem:** in cheapest PC-desktop/laptop a radiologist (or any human at all) distinguishes sRGB "gray 0..255 " (within 1..3 LeastSignificantBits) in default MacBook ~ 4 LSB in dark gray-tones disappear (i.e "gray 0" appears absolutely same as "gray 16") in default iPAD ~ 3 LSB in dark gray-ones disappear (i.e "gray 0" looks identical to "gray 8") 3) The question: = what could be stated in user-manual of a radiology-gadget to guide an end-user ?... = to adjust still gray-scale image_presentation of 8-bit BMP, PNG, GIF, TIFF, DCM (~sRGB-color-space) in: 3a) MacBook "AppleSilicon", 3b) iPAD "AppleSilicon"; assuming standard preview_app, Osirix, ImageJ; assuming that one places "3a,3b" near against cheapest PC-display on market; = so that: "gray 0..16" and "gray 240..255" are distinguishable in "3a,3b" not much worse tnan in cheapest PC-display 4) Comment 4a) Apple's PTC seemingly is weird S-like curve, to improve moving_imaging_impression sacrificing objective information of still-imaging presentation. 4b) Alternate color-profiles in MacBook's system_setting are 100% useless for the task. 4c) Adjust of white_point in MacBook,iPAD is <99%> useless for still radiology imaging (which needs adjustment of the black_point). 4d) Dedicated S-curve-like XLAT from PC-sRGB to APple's gray-scale isn't suitable, because of = the gadget is most world-wide-spread of it's case; = experience of existing Windows, Android-users can't be disturbed by few potential MAC-users; = double XLAT "sRGB => adhoc_color_space =>sRGB" (without overcomplicated & non_robust sentinels) causes pixellation (i.e. ~"gray 3.4.5" all become "gray 4")

Hello, I'm using the custom symbol feature in the official SF Symbols app. I'm wondering if there is a way to sync my custom symbols across different devices? Since I have multiple Macs to work on, maybe iCloud?

I am running into an issue with the latest 2 beta drops of 18 when using Stage Manager with an external monitor. I have the ipad directly below the monitor and when I move the mouse to the other screen it shifts dramatically right then go to the proper position about an inch up the screen. This issue can easily be duplicated. I can share a video if I am given the proper way to do so. This worked fine with the first beta release. Please contact me because it will cause issues when the gold release is dropped. I have found smaller bugs but this is bad.

it’s a cool concept, i see the vision, but it’s really ugly. all my app colours have changed, none of my transparent widgets work anymore because it changed the size of my wallpaper. i do like how the brightness and volume are now colours, i just wish we could’ve gotten to choose the colours. i also like how the things are circles instead of squares. i’m mostly just upset that my transparent widgets don’t work anymore, and how all the colours of all my apps are darker than i would like.

I have an iPhone 14 with the iOS version 18 Beta Version. My phone does not ring. Callers are immediately prompted to leave a voicemail. Even my wife, who is designated a favorite has this happen. I’ve gone to Settings and checked Sounds & Haptics. It appears to be set correctly. Please help. Should I go to the local Apple Store for hands on help? Thank you. Bo Kirk

I know that the general San Francisco (SF) fonts (Text, Display, Pro, etc.) are exclusive to Apple, its products, and its affiliates. But when it comes to SF Mono, I am unsure of its official status. Is it open source? I know many companies often release their monospace font under the OFL license (i.e., Twilio Sans Mono, Intel One Mono, Ubuntu Mono (et al), Roboto Mono (et al), and more). As I've previously said, I also know that Apple is very protective it its brand. The thing that really confuses me is that the page for Microsoft's Open Source projects (opensource.microsoft.com) actually uses SF Mono! Are Apple and MS collaborating on this? There is no repository on GitHub or the Apple Developer website, but why is a competitor to Apple using their font? (I am using Windows, so the SF fonts aren't installed on my device, they use the font from their own CDN on their website)

Please make the apps be able to be white and a color like you did with black

Can we get a customizable iMessage color change???? That would be great. Would love to change my blue bubble to either yellow or pink!!!!!

Hi everyone, I have a file with a navigation stack and i want the background of it to be a blurred image however there's like a line dividing the body of the navigation stack and the navigation bar where the image isn't being blurred, is there any way to get rid of this and make it so the blurred image background connects the two? i've already tried changing the appearance of the navigation bar when it's initialized. I also have my code below for reference: var body: some View { NavigationStack { ZStack { Image("HomeBKG") // this is the background image .resizable() .scaledToFill() .ignoresSafeArea() VisualEffectBlur(effect: UIBlurEffect(style: .systemMaterial)) // this is what i used to blur the image .ignoresSafeArea() ScrollView { ColorManager.bkgColor .ignoresSafeArea() VStack { Text("Recommended") .foregroundStyle(.primary) .font(.headline) .padding() RoundedRectangle(cornerRadius: 15) .frame(width: 300, height:200) .foregroundStyle(Color(UIColor.systemBackground)) .shadow(color: .primary.opacity(1), radius: 10) Spacer() Text("News") .foregroundStyle(.primary) .font(.headline) .padding() RoundedRectangle(cornerRadius: 15) .frame(width: 300, height:200) .foregroundStyle(Color(UIColor.systemBackground)) .shadow(color: .primary.opacity(1), radius: 10) Text("Exchange Rates") .foregroundStyle(.primary) .font(.headline) .padding() RoundedRectangle(cornerRadius: 15) .frame(width: 300, height:200) .foregroundStyle(Color(UIColor.systemBackground)) .shadow(color: .primary.opacity(1), radius: 10) } } // end zstack } .navigationTitle("Hub") .toolbar { ToolbarItem(placement: .navigationBarTrailing) { NavigationLink(destination: UVSettings()) { Image(systemName: "gearshape.fill") } } } } // end navigation stack } }` ```

Hello , I am developing mobile apps in B2C model for Service industry and would like to know if the Merchant API (see below) can be used within the iOS app to onboard a Merchant . Typical case for the API here would be for E Commerce platform providers to onboard the customers in the web . However here, Instead of Web, this API would be integrated within the iOS APP. Service providers would download my App and within the App , service providers would provide the information to register for Apple Pay so that they can receive the payment directly from customer instead of using a payment platform like Stripe. Please advise if this is technically feasible . https://developer.apple.com/documentation/applepaywebmerchantregistrationapi Thanks, Jmkochi

Quite disappointed to find out my iPad Pro 2020 did not support script handwriting in the note app from what I’ve searched for it seems it needs the M1 chip really

Hi, with reference to the project seen here: https://twitter.com/Volorf/status/1813177399078514884 I've been having a hard time to replicate an 3D-animated stepper button, where the button gets depressed spatially when you click on it. Does anyone know the framework to how this should be done? I appreciate your help.

I'm trying to implement interactive graphs, but find that the .chartOverlay property includes the axes and legend. How do I find only the rectangle that contains the data?

I have new idea about how IPhone should be designed

Hi, I was searching and replacing code where all of the sudden I got the following errors: Undefined symbol: AppName.Client.init(id: Swift.Int, name: Swift.String, StructVariable: Swift.Int?, structVariable: [Struct]?) -> AppNameStruct Linker command failed with exit code 1 (use -v to see invocation) I replaced the names in the first error message for privacy reasons. I tried quitting Xcode and restarting my computer but the error persisted. Any help on resolving this would be greatly appreciated.

Does anyone know how to localize the title of the shortcut? I tried to create a localizable file and then do a french translation. However, when I reference it as my shortcut title and change my simulator's language to the translated language (in this case french) it still displays the title in the english translation. for example: my Localizable.strings file says in english: "shortcutTitle" = "Hello!"; in french: "shortcutTitle" = "Bonjour!"; and then my AppIntent says: static var title: LocalizedStringResource{return LocalizedStringResource("shortcutTitle")}
