I'm currently developing a SwiftUI application that utilizes SwiftData for data management. I am facing a challenge when trying to filter a query. Specifically, I want to filter a list of Item objects to match a Product instance that is passed to my View. error : Instance member 'product' cannot be used on type 'MainItemListEncap'; did you mean to use a value of this type instead The view // // 311.1.1. MainRefToItem.swift // ComparePrice // // Created by Herman VAN CAUWELAERT on 11/12/2024. // import SwiftUI import SwiftData struct MainItemListEncap: View { @Bindable var product: Product @Query( filter: #Predicate { item in item.productGroup == product }, sort: [SortDescriptor(\Item.name)] ) var items: [Item] @Environment(\.modelContext) var modelContext var body: some View { ForEach(items) { item in VStack(alignment: .leading) { Text(item.name) Text(item.description) } } } } the product class. import SwiftData import Foundation @Model final class Product: CustomStringConvertible, CustomDebugStringConvertible { @Attribute(.unique) var productName: String var productDescription: String var outputCurrency: String // Gebruik een `String` als opslag voor `outputSystem` var outputSystemRawValue: String = MeasurementSystem.metric.rawValue // Computed property om `MeasurementSystem` te gebruiken var outputSystem: MeasurementSystem { get { MeasurementSystem(rawValue: outputSystemRawValue) } set { outputSystemRawValue = newValue.rawValue } } // er zijn verschillend item versies voor een product // als er een hoofdproduct gedelete wordt, dan zullen alle onderliggende items ook gedelete worden @Relationship(deleteRule: .cascade, inverse: \Item.productGroup) var refToItems = [Item]() init(productName: String = "", productDescription: String = "what is this product", outputCurrency: String = "EUR", outputSystem: MeasurementSystem = MeasurementSystem.metric) { self.productName = productName self.productDescription = productDescription self.outputCurrency = outputCurrency self.outputSystem = outputSystem } } the item class import Foundation import SwiftData @Model final class Item: CustomStringConvertible, CustomDebugStringConvertible { var timestamp: Date @Attribute(.unique) var name: String var productGroup: Product? var shop: String //TODO: becomes Shop var price: Double var currency: String var quantity: Double var unit: String //TODO: becomes Unit var isShown : Bool var minimumQuantity: String var rateStr: String { conversionRate != nil ?

Hi everyone, I’m a developer from Argentina, and I recently attempted to publish my app on Google Play under a US LLC. I submitted all the required documentation and followed the process step-by-step. After 40 days of back-and-forth communication and providing all the requested information, my application was ultimately rejected without a clear explanation. I understand that having a US company and bank account is a requirement for developers like me to operate internationally, but this rejection has left me quite confused about what went wrong. Has anyone else faced a similar situation? If so, how did you resolve it? Any advice or guidance would be greatly appreciated! Thanks in advance!

“At this rate, I’m starting to get frustrated. I’ve registered for the developer program twice, but they’re still asking me for the registration fee, and my registration is not being approved. Moreover, I haven’t received any response to my emails, and since the information is limited in English, I can’t search for solutions. Could someone please take care of this issue now?”

I'm a developer that has only produced for a single company. Though my developer account shows me as the account holder, my "Enrolled as" status is "Organization," and the "Entity" field shows the name of that company. I want to build an app for a separate company/organization, but unsure how to proceed. My App Store Connect account shows the original company name beneath my name as the only option in the account ID selector menu, so when I begin the New App process it automatically assumes I'm doing it for that company. Can I change my "Enrolled as" status to something independent of any organization, do I need to create a completely separate account to do this, or how should I proceed? Any help would be appreciated. Thanks.

Hello, We’re experiencing an issue in our app where a subset of users are being logged out automatically without any apparent reason. This is impacting both iOS 16 and iOS 17 users (though it’s hard to confirm if it’s platform-specific). Here’s a breakdown of the situation: Symptoms Some users report being logged out of the app randomly, even after remaining active. The issue doesn’t seem to affect all users—just a specific subset. Users are prompted to log in again, and once they do, the app behaves as expected until the issue recurs.

I have developed a mobile app using SwiftUI that supports GoogleMaps. Now I am in the process of building a CarPlay application. I assume CarPlay only supports Apple MapKit, as I could not find any way to integrate the Google Maps. Below are few queries, Could you please guide me on how I can obtain the user's current location on the CarPlay app launch? Is there a way CarPlay can get the details from the mobile app(not pretty sure as its using Google Maps)? If the user is logged out from the mobile app, what is the flow in CarPlay? Do we have any standard login page asking user to login to the mobile app first? Is there any UI asking the user to capture the location in CarPlay? This is my first CarPlay app. Kindly guide me to a document or so that covers these details. Thanks a ton!!

Hi all, The use of setVoiceProcessingEnabled increases the channel count of my microphone audio from 1 to 5. This has downstream effects, because when I use AVAudioConverter to convert between PCM buffer types the output buffer contains only silence. Here is a reproduction showing the channel growth from 1 to 5: let avAudioEngine: AVAudioEngine = AVAudioEngine() let inputNode = avAudioEngine.inputNode print(inputNode.inputFormat(forBus: 0)) // Prints <AVAudioFormat 0x600002f7ada0: 1 ch, 48000 Hz, Float32> do { try inputNode.setVoiceProcessingEnabled(true) } catch { print("Could not enable voice processing \(error)") return } print(inputNode.inputFormat(forBus: 0)) // Prints <AVAudioFormat 0x600002f7b020: 5 ch, 44100 Hz, Float32, deinterleaved> If it helps, the reason I'm using setVoiceProcessingEnabled because I don't want the mic to pick up output from the speakers. Per wwdc When enabled, extra signal processing is applied on the incoming audio, and any audio that is coming from the device is taken Here is my conversion logic from the input PCM format (which in the case above is 5ch, 44.1kHZ, Float 32, deinterleaved) to the target format PCM16 with a single channel: let outputFormat = AVAudioFormat( commonFormat: .pcmFormatInt16, sampleRate: inputPCMFormat.sampleRate, channels: 1, interleaved: false ) guard let converter = AVAudioConverter( from: inputPCMFormat, to: outputFormat) else { fatalError("Demonstration") } let newLength = AVAudioFrameCount(outputFormat.sampleRate * 2.0) guard let outputBuffer = AVAudioPCMBuffer( pcmFormat: outputFormat, frameCapacity: newLength) else { fatalError("Demonstration") } outputBuffer.frameLength = newLength try! converter.convert(to: outputBuffer, from: inputBuffer) // Use the PCM16 outputBuffer The outputBuffer contains only silence. But if I comment out inputNode.setVoiceProcessingEnabled(true) in the first snippet, the outputBuffer then plays exactly how I would expect it to. So I have two questions: Why does setVoiceProcessingEnabled increase the channel count to 5? How should I convert the resulting format to a single channel PCM16 format? Thank you, Lou

This wasn't happening until I updated Xcode to 16.2 (I'm using Sequoia 15.2). When I run any Mac app, I get these errors: Can't find or decode reasons Failed to get or decode unavailable reasons Can't find or decode disabled use cases I even got these errors running "Hello, world" which tells me that either I need to reinstall or there is a bug. Thanks for any help, -Ashley

Hi, After updating to Xcode 16.2, I am getting an error running all iOS apps. I'm using Sequioa 15.2. Error creating the CFMessagePort needed to communicate with PPT. I ran the default Hello World app and got the same error message (plus another error not showing up on my apps - Failed to send CA Event for app launch measurements for ca_event_type: 1 event_name: com.apple.app_launch_measurement.ExtendedLaunchMetrics). Can I ignore the error or is it truly affecting my app (all are testflight versions and it's fine if I don't update them for awhile, although not ideal). Hopefully someone can help! Thanks, -Ashley

Like I said in the title, it looks like MetalTools.framework is missing or corrupted. I think I saw that the symbolic link was broken. They look like aliases in the finder, but I can't find the original. This was a problem with Ventura (using the last compatible Xcode version) and Sequoia 15.2 (Xcode 16.2). I didn't use Xcode before that. Note that none of my apps need Metal API (I don't think). I only noticed it when Xcode gave an error regarding Metal. Sorry this is so long; I hope the Terminal info will help. I don't want to reinstall Sequoia and this has been a problem since at least Ventura.

After Updating My iPhone 15 Pro To IOS 18.3 beta, 1 Day Later A Pixel seemed stuck or burnt, and then after 1 Day on 25 Dec The Screen Went Black Or Turned Off But Responded To My Touch, the reason i suppose the screen went black would be a memory glitch happening when i opened the camera from the Lock Screen or a graphica card issue if anyone can help I would appreciate it

I bought Pioneer SPH-DA97DAB CarPlay radio but hardly can use the phone due to a loud echo that the caller hears during a call. how can I solve this does CarPlay has echo cancelation?

Hi all, if anyone from apple Dev team is seeing this, please do consider supporting device mirroring without the need to login to icloud and with cable connection in addition to wi-fi. I am working in a corporate setting which does not allow us to login to icloud, thus I am unable to use device mirroring when my work really needs is, I am stuck with Quick time preview. I am quite sure, that this does not only apply to me.

15.2 has a major problem with Thunderbolt devices. Dozens of reports on the discussion forum after people upgraded from prior versions. In my case 15.1 was working flawlessly. After upgrading to 15.2 the MAC PRO (2019) won't even boot with multiple Thunderbolt devices attached. If as suggested I disconnect all those devices the MAC boots but I no longer have my Thunderbolt drives available. Someone from Apple really needs to start listening to this. We have posted feedback after feedback and I keep getting told no one else has this problem. Well 4 pages of people on the discussion forum would disagree with that.
