Hi, I'm trying to create a visualization using charts for vision pro. I want to create a line chart that connects pair of points on a donut chart. So i'm trying to draw the lines radially but it seems that the line chart always has only the bottom left corner of the view as origin. How can I tranform the origin to center of the view?

When using a double-tap primary action on a button, there will be a 1 second delay before the action is executed after the double-click is detected. Why is the design not like scrollview, which executes actions after double-tap detection? Is there a way to make the button perform an action after detecting a double-tap?

Hello everyone, I'm developing an app using RoomPlan where users can capture several rooms individually and assign custom names to each room. When I merge these captured rooms into a single CapturedStructure using the StructureBuilder, I want the merged structure to retain the original sections with their custom labels. However, I'm encountering an issue: Problem: After merging, the CapturedStructure's sections have different identifiers (UUIDs) compared to the original sections in the individual CapturedRooms. This means there's no straightforward way to map the custom labels from the original rooms to the sections in the merged structure. What I've Tried: Mapping by Identifiers: Attempted to map custom labels using the sections' identifiers, but the identifiers change during the merge, making this ineffective. Mapping by Positions: Tried matching sections based on their center positions (simd_float3), but these change. Modifying Section Labels: Considered changing the label property of the sections before merging, but the label is read-only and cannot be modified directly, and the CoreModel is used for merging rather than the data that can be modified via json. Question: Is there a recommended way to preserve or map custom section labels when merging multiple CapturedRooms into a single CapturedStructure using RoomPlan? How can I ensure that the custom labels assigned to rooms before the merge are correctly associated with the corresponding sections after the merge? Any guidance or suggestions would be greatly appreciated! Thank you!

Hello, I am an app developer from China. We are developing a mobile game that will be released on iOS and Android platforms (as well as some PC and Mac platforms). The game is a commercial app. My question is: we would like to use the "PingFang" Chinese font in our game software. Do we need to obtain a license, and how should we go about obtaining it? (For example, through which channels should we apply for the license, and what are the associated fees?)

I'm trying to download version 2.1 of SF symbols even though version 6 is out because I have a older macOS but I can't find it. So, how would I work around this?

Hi, starting from iOS18, it is impossible to differentiate between completed meetings and future meetings in calendar - almost the same color (unless I switch to dark mode). Is there a way to fix it or is it a human engineering bug?

In Carplay, is it possible to update the navigation title and also add right tab bar items? Couldn't find these details in the documentation. Please suggest

Hi there, I'm working on a product which needs to pair with an iOS device (only iPad and iPhone) via Bluetooth. I already have the device pairing and operating fully with android or Windows hosts and have implemented BLE. Obviously, iOS isn't as simple as those for pairing. The product type is not listed under the MFi accessories. The question I have is what hardware and or firmware needs does the product needs to fulfil in order to pair/bond fully. I've seen some devices have a MFi security chip, some need to be manufactured in a MFi approved facility, I've no idea on the firmware requirements. We're starting the process of joining the MFi program too. So: Do I need the security chip? Where is the pairing process documented? Can I use BLE or do I need to use classic Bluetooth or core Bluetooth? Any help would be greatly appreciated because I'm kind of lost. Thanks, Louis

Hi,After I tried to submit my APP for review several times, it was still rejected for the following reasons: Guideline 4.1-Design-Copycats: The app or its metadata appears to contain potentially misleading content. Specifically, the app includes content that resembles ODIKING without the necessary authorization. But odiking belongs to our company's product, I don't know the problem, I don't understand how to prove that this product does not belong to a third party content Tanks1

I have an iPhone/iPad application for which there is no watchOS target and as such no separate Watch app. I do not have separate watchOS app icons included as well in Assets. However, an Apple Watch is supposed to receive push notifications for the application. Do we as app developers need to provide watchOS app icons, with different resolutions as suggested by Apple in HIG, in app's Assets for the app logo to appear properly in the notification coming in watch, for both short look and long look? As of now, my app's icon appear pixelated in short look and I am not sure whether it is an app icon issue or because I did not include watchOS app icons in Assets.

Hi, When using just one model container, I have the following code: let modelContainer: ModelContainer init() { do { entriesModel = try ModelContainer(for: Model.self) } catch { fatalError("Could not initialize ModelContainer") } } I am attempting to implement two like so: let model1: ModelContainer let model2: ModelContainer init() { do { model1 = try ModelContainer(for: Model1.self) model2 = try ModelContainer(for: Model2.self) } catch { fatalError("Could not initialize ModelContainer") } } var body: some Scene { WindowGroup { ContentView() .modelContainer(model1) .modelContainer(model2) } } However, when in the Views that I'd like to implement I don't know how to declare the models. I tried this: @Environment(\.model1) private var model1 @Query private var data: [Model1] But I get the error: Cannot infer key path type from context; consider explicitly specifying a root type How do I implement multiple model containers in multiple different views?

Hello, I've been trying to imagine how to support ensuring the display of my tips in the order I want them to for iOS 17. I am familiar with the TipGroup iOS18 feature, but I'm looking to control the order without TipGroup so I can deliver a great user experience in my iOS 17 and > app. I've tried lots of theories, but can't seem to figure it out and I don't see anyone else having solved it. Any ideas/code examples anyone could point me to? Thanks!

1, I add an Matter extension named TRMatterExtension, using the Template in Xcode. 2, check the InfoPlist with the TRMatterExtension module, I see the NSExtension key with two key which are like this: 3,The RequestHandler.swift file is like this: import os import MatterSupport let logger = Logger(subsystem: "com.airdroitech.commissionMtr2", category: "MatterExtension") // The extension is launched in response to MatterAddDeviceRequest.perform() and this class is the entry point // for the extension operations. class RequestHandler: MatterAddDeviceExtensionRequestHandler { override init() { logger.log("QAWI3 - init") super.init() } override func validateDeviceCredential(_ deviceCredential: MatterAddDeviceExtensionRequestHandler.DeviceCredential) async throws { // Use this function to perform additional attestation checks if that is useful for your ecosystem. logger.log("QAWI3 - validateDeviceCredential") } override func selectWiFiNetwork(from wifiScanResults: [MatterAddDeviceExtensionRequestHandler.WiFiScanResult]) async throws -> MatterAddDeviceExtensionRequestHandler.WiFiNetworkAssociation { // Use this function to select a Wi-Fi network for the device if your ecosystem has special requirements. // Or, return `.defaultSystemNetwork` to use the iOS device's current network. logger.log("QAWI3 - Returning default system network") return .defaultSystemNetwork } override func selectThreadNetwork(from threadScanResults: [MatterAddDeviceExtensionRequestHandler.ThreadScanResult]) async throws -> MatterAddDeviceExtensionRequestHandler.ThreadNetworkAssociation { // Use this function to select a Thread network for the device if your ecosystem has special requirements. // Or, return `.defaultSystemNetwork` to use the default Thread network. return .defaultSystemNetwork } override func commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) async throws { // Use this function to commission the device with your Matter stack. logger.log("QAWI3 - Starting commissioning flow") } override func rooms(in home: MatterAddDeviceRequest.Home?) async -> [MatterAddDeviceRequest.Room] { // Use this function to return the rooms your ecosystem manages. // If your ecosystem manages multiple homes, ensure you are returning rooms that belong to the provided home. return [.init(displayName: "Living Room")] } override func configureDevice(named name: String, in room: MatterAddDeviceRequest.Room?) async { // Use this function to configure the (now) commissioned device with the given name and room. } } 4, I add Privacy - Local Network Usage Description and Bonjour services [ _matter._tcp _matterc._udp _matterd._udp ] to the main target's InfoPlist. 5, click a button to call MatterAddDeviceRequest.perform(), the code is as the following: let homes = [MatterAddDeviceRequest.Home(displayName: "TRHome")] let topology = MatterAddDeviceRequest.Topology(ecosystemName: "TR", homes: homes) let request = MatterAddDeviceRequest(topology: topology) do { try await request.perform() print("Successfully set up device!") } catch { print("Failed to set up device with error: (error)") } 6, Result: Most times, Matter devices can be added to the KeyChain and the commission window of the Matter device could be opened. But sometimes the MatterSupport window will show "Pairing Failed". The total error is: [1E1D8753] Failed to perform Matter device setup setup: Error Domain=HMErrorDomain Code=18 "Pairing Failed" UserInfo={HFErrorUserInfoOptionsKey={ HFErrorUserInfoOptionDescriptionKey = "Pairing Failed"; HFErrorUserInfoOptionTitleKey = "\U65e0\U6cd5\U6dfb\U52a0\U914d\U4ef6"; }, NSLocalizedDescription=Pairing Failed, NSUnderlyingError=0x3009e8240 {Error Domain=HAPErrorDomain Code=15 "Failed to pair Matter Accessory in time" UserInfo={NSLocalizedDescription=Failed to pair Matter Accessory in time, NSUnderlyingError=0x3009e86c0 {Error Domain=HAPErrorDomain Code=24 "(null)"}}}}. From the log I can see, the Function selectWiFiNetwork(from wifiScanResults: [MatterAddDeviceExtensionRequestHandler.WiFiScanResult]) async throws -> MatterAddDeviceExtensionRequestHandler.WiFiNetworkAssociation of the RequestHandler.swift file will be called and commissionDevice(in home: MatterAddDeviceRequest.Home?, onboardingPayload: String, commissioningID: UUID) will NOT called. Sometimes the RequestHandler class will not be called at all, this means the first function validateDeviceCredential will not be called. But ,when this happens, the iPhone will Continuously can NOT add device for a long time, sometimes it gets better inexplicably. Even under normal circumstances, the probability of successfully adding a device is less than 50% and very slowly. When using Apple Home app, the success rate is very high, almost 100%, and very fast. So, can you help me identify where the problem is and what areas need attention? Thank you very much! Finally, I often encounter logs like this: nw_browser_dns_service_browse_callback [B3] not in ready or waiting state Do you know what it means and whether it will affect the equipment distribution network? My testing machine is iPhone 12, operating on iOS 18 and above 17.0. Thank you very much!

Hello, I'm developing an iOS app in Flutter, but I'm having trouble enabling Background Mode. I added the following configuration to Info.plist and Runner.entitlements: <key>UIBackgroundModes</key> <array> <string>processing</string> <string>fetch</string> <string>location</string> </array> However, the Background Mode option doesn't appear in my App ID to be enabled. And the build fails with the message: Provisioning profile "Ready Response ios_app_store ..." doesn't include the UIBackgroundModes entitlement. How can I enable this option in my App ID? Note: I'm using Android Studio and publishing through Codemagic.

Hi, Our application is a B2B app, supporting users from companies that own our equipment (print industry). We want to allow company stakeholders to have a "Premium Plan" that will provide their company with numerous advantages in different aspects (service, training, data visibility) Some features in our app will be locked/hidden if the company is not part of the Premium Plan. We want to allow authorized users to activate the Premium plan for their entire company. We already have our website, where we already have a marketplace that allows web users to do this (using their company service agreement). In term of complying with Apple's in-app purchase Policy, is it ok to tell users in the app to go to this marketplace if they want these features (and more)? Thank you

I am working on a MapView with MapAnnotation on the Map and am having difficulty getting the MapAnnotation to function properly when selected. In my code, I want the MapAnnotation selected to be to the front if it is behind or partially blocked by another annotation. I have tried using a zIndex but this does not appear to work.
