Hi everyone, I am fairly new to Apple development. I have been working on a project where I need Mac to interface with an HID device (custom device). I have successfully communicated with the device using IOKit, Core Foundation and Driver Kit frameworks by simply importing these frameworks in the project and making use of their APIs. However, my client is now asking that I develop the communication explicitly using HID Driver Kit. Bear in mind that I have not purchased the apple developer certificate nor do I have any provisional signing certificates and without any of these, Xcode was allowing me to use frameworks like IOKit, DriverKit etc. Now, when I tried importing HIDDriverKit into the project, I am not able to find this framework in the "Frameworks and Libraries" tab. How do I import this framework into my project? Do I have to purchase apple developer ID or get the provisional signing certificates or any other formalities are required? Please let me know what can be done. Any pointers or suggestions are welcome. Best, Vishnu

Hello everyone, I am having an issue in Xcode after updating to version 14.3.1 and I'm hoping someone might be able to help me. I am working on macOS 13.4.1. I'm trying to integrate the Firebase SDK (version 8.15.0) into my project through Cocoapods. The specific Firebase frameworks I am using are FirebaseAnalytics, FirebaseAuth, FirebaseCore, FirebaseDynamicLinks, FirebaseFirestore, FirebaseInstallations, FirebaseMessaging, and FirebaseStorage. Despite installing these successfully, I am facing an error that states "Framework not found Firebase". It does not specify any particular Firebase framework that's missing. I have attempted several potential solutions such as reinstalling pods, cleaning the project, deleting derived data, and even switching the package manager from Cocoapods to Swift Package Manager. I've also tried adjusting the header paths. Unfortunately, none of these methods have resolved the issue. Below is the error message from my log: ld: warning: directory not found for option '-F/Users/oscarnilsson/Library/Developer/Xcode/DerivedData/Aircutt_Business-cibnpzcszsymgwgztnynnwvihkub/Build/Products/Debug-iphoneos/FirebaseAppCheckInterop' ld: warning: directory not found for option '-F/Users/oscarnilsson/Library/Developer/Xcode/DerivedData/Aircutt_Business-cibnpzcszsymgwgztnynnwvihkub/Build/Products/Debug-iphoneos/FirebaseAuthInterop' ld: warning: directory not found for option '-F/Users/oscarnilsson/Library/Developer/Xcode/DerivedData/Aircutt_Business-cibnpzcszsymgwgztnynnwvihkub/Build/Products/Debug-iphoneos/FirebaseCoreExtension' ld: warning: directory not found for option '-F/Users/oscarnilsson/Library/Developer/Xcode/DerivedData/Aircutt_Business-cibnpzcszsymgwgztnynnwvihkub/Build/Products/Debug-iphoneos/FirebaseCoreInternal' ld: framework not found Firebase clang: error: linker command failed with exit code 1 (use -v to see invocation) Has anyone experienced a similar issue or does anyone have any insights into what could be causing this? Any help would be greatly appreciated. Best, Oscar

Hi, My SwiftUI app uses a third-party framework (written in objc, say with name Foo) that is built into a XCFramework. I can build and run this app in iOS simulator and an iPhone connected to my Mac. But when I do "Product" -> "Archive", it fails with the error: Cannot find 'Foo' in scope The error is reported at anywhere that uses things like Foo.bar(). Why would Archive fail while both simulator and real device works with the framework? What's the extra thing does Archive do? XCode version: 14.2 Target setting -> General -> Frameworks, Libraries and Embedded Content: "Embed & Sign". Thanks.

Hi All, I created our own framework called Framework A (which has its own Podspec and googlecast as dependency in it). I also created framework B (which has its own Podspec))and framework c (which has its own Podspec))where both uses the Framework A (using the pod). Since googlecast is dependent, it is inside Framework A, Framework B and Framework C I am created the sampleApplication and add Framework A , Framework B and Framework C in the pod file pod filee : pod 'framework A' pod 'Framework B' pod 'Framework C' After pod install, While trying to run thee application I am getting this error Class GCKUICastButton is implemented in both /private/var/containers/Bundle/Application/B4F23931-F41B-45C2-AEFA-4587C81D9474/sampleApp.app/Frameworks/Framework B.framework/framework B (0x108784a28) and /private/var/containers/Bundle/Application/B4F23931-F41B-45C2-AEFA-4587C81D9474/sampleApp.app/Frameworks/Framework C.framework/Framework C (0x1053afb18). One of the two will be used. Which one is undefined. After this Googlecast feature are breaking like cars button icon is disappearing. Please help me in solving this problem

I get this error message : The error is not from algolia but from cocoap or xcode because Algolia is only the first framework in the install list and when I remove it from podfile I get the same error with the second framework. I tried many thing, clean build folder, delete derived data, restart mac, uninstall and reinstall all pod files. I hope someone can help me solve this problem!

I am creating an application for ios. I include two static libraries in my application. However, if the same function name exists in two static libraries, the function that was first included as a library will be called. (Static library written in Objective-c) Is there any way to solve this? Is it possible to solve it by using framework? Note that the function names of the library are specified by the standard, so the function names cannot be changed. Best regards.

my content netfilter systemextension is like this: class FilterDataProvider: NEFilterDataProvider { override func startFilter(completionHandler: @escaping (Error?) -> Void) { let ipv4LocalHost = NWHostEndpoint(hostname: "127.0.0.1", port: "0") let ipv4LocalNetworkRule = NENetworkRule(remoteNetwork: ipv4LocalHost, remotePrefix: 0, localNetwork: ipv4LocalHost, localPrefix: 0, protocol: .any, direction: .any) let ipv4LocalFilterRule = NEFilterRule(networkRule: ipv4LocalNetworkRule, action: .filterData) let ipv6LocalHost = NWHostEndpoint(hostname: "::1", port: "0") let ipv6LocalNetworkRule = NENetworkRule(remoteNetwork: ipv6LocalHost, remotePrefix: 0, localNetwork: ipv6LocalHost, localPrefix: 0, protocol: .any, direction: .any) let ipv6LocalFilterRule = NEFilterRule(networkRule: ipv6LocalNetworkRule, action: .filterData) let normalNetworkRule = NENetworkRule(remoteNetwork: nil, remotePrefix: 0, localNetwork: nil, localPrefix: 0, protocol: .any, direction: .any) let normalFilterRule = NEFilterRule(networkRule: normalNetworkRule, action: .filterData) let filterSettings = NEFilterSettings(rules: [ipv4LocalFilterRule, ipv6LocalFilterRule, normalFilterRule], defaultAction: .filterData) apply(filterSettings) { error in completionHandler(error) if error != nil { log.error("Failed to apply filter settings [\(error!)]") } else { log.info("Start content filter successfully.") } } } override func handleNewFlow(_ flow: NEFilterFlow) -> NEFilterNewFlowVerdict { return .allow() } } when startFilter is called, all tcp connections disconnected, but i can connect again.

I have a critical issue where my websocket will not connect to a server that is sitting behind an NGINX reverse proxy only on iOS 13. I have tested on both a real device and simulator with no success. It simply hangs on preparing. it never receives updates to the viabilityUpdateHandler and only ever enters the preparing state of the stateUpdateHandler. On any iOS greater or equal to iOS 14 it works seamlessly. I can connect to a local server that is not dealing with any certificates on iOS 13 no problem, but when my production server is in play it does not communicate something properly. I am using NWConnection's NWProtocolWebSocket. The setup is basic and straight forward let options = NWProtocolWebSocket.Options() options.autoReplyPing = configuration.autoReplyPing options.maximumMessageSize = configuration.maximumMessageSize if configuration.urlRequest != nil { options.setAdditionalHeaders(configuration.urlRequest?.allHTTPHeaderFields?.map { ($0.key, $0.value) } ?? []) _ = configuration.cookies.map { cookie in options.setAdditionalHeaders([(name: cookie.name, value: cookie.value)]) } } if !configuration.headers.isEmpty { options.setAdditionalHeaders(configuration.headers.map { ($0.key, $0.value) } ) } let parameters: NWParameters = configuration.trustAll ? try TLSConfiguration.trustSelfSigned( configuration.trustAll, queue: configuration.queue, certificates: configuration.certificates) : (configuration.url.scheme == "ws" ? .tcp : .tls) parameters.defaultProtocolStack.applicationProtocols.insert(options, at: 0) connection = NWConnection(to: .url(configuration.url), using: parameters) The trust store is also straight forward public static func trustSelfSigned(_ trustAll: Bool, queue: DispatchQueue, certificates: [String]? ) throws -> NWParameters { let options = NWProtocolTLS.Options() var secTrustRoots: [SecCertificate]? secTrustRoots = try certificates?.compactMap({ certificate in let filePath = Bundle.main.path(forResource: certificate, ofType: "der")! let data = try Data(contentsOf: URL(fileURLWithPath: filePath)) return SecCertificateCreateWithData(nil, data as CFData)! }) sec_protocol_options_set_verify_block( options.securityProtocolOptions, { _, sec_trust, sec_protocol_verify_complete in guard !trustAll else { sec_protocol_verify_complete(true) return } let trust = sec_trust_copy_ref(sec_trust).takeRetainedValue() if let trustRootCertificates = secTrustRoots { SecTrustSetAnchorCertificates(trust, trustRootCertificates as CFArray) } dispatchPrecondition(condition: .onQueue(queue)) SecTrustEvaluateAsyncWithError(trust, queue) { _, result, error in if let error = error { print("Trust failed: \(error.localizedDescription)") } print("Validation Result: \(result)") sec_protocol_verify_complete(result) } }, queue ) sec_protocol_options_set_min_tls_protocol_version(options.securityProtocolOptions, .TLSv12) let parameters = NWParameters(tls: options) parameters.allowLocalEndpointReuse = true parameters.includePeerToPeer = true return parameters }

I am attempting to implement the Tap to Present ID (Data Request) feature and am wondering if the Data Request will succeed without a reader token. From the wording in the WWDC video (31:50 in WWDC2023-10114 video), it sounds the reader token is necessary, but the example is building off of the previous MobileDriversLicenseDisplayRequest example where the the reader token was used only for the branding to be displayed. In my app running on Simulator, I'm able to get the placeholder data to return from a MobileDriversLicenseDataRequest without using a reader token. Since I'm unable to test this on physical device (I don't live in a state that has Mobile ID's), I'm hoping an Apple engineer can comment on if the reader token is required strictly for the branding to be presented, and not for the Data Request itself to succeed. Thank you.

What is the highest level of location precision achievable with the WeatherKit API? When latitude and longitude are given up to the fifth decimal place, the precision is around 1 meter. Could this ever be more accurate than providing the lat/long to the fourth decimal place, which has a precision of about 10 meters?

Hello everyone, I am working on an app and need to find an API that can return articles about travel. Has anyone ever done something like this? Any help is appreciated. Thank you,

I have a framework (MyFramework) in which I want to use an existing dynamic framework via SPM (called now MyDynamicFramework). I included it as a package dependency and all seems to be good: Then, I created a test application in which I simply include my framework with Enbed & Sign. When I run this test application, it all works fine in simulator, but in real device I get the following signing-related issue: dyld[24248]: Library not loaded: @rpath/MyDynamicFramework.framework/MyDynamicFramework Referenced from: <ED356026-4AD8-3AD4-9CD7-BE977EE551E4> /private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/MyFramework Reason: tried: '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' (no such file), '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' (code signature in <2BD920A5-1906-31B6-99B9-18DE47F02514> '/private/var/containers/Bundle/Application/432B2A6D-55A7-4C9D-8EA2-622B81E215EA/MyFrameworkTestApp.app/Frameworks/MyFramework.framework/Frameworks/MyDynamicFramework.framework/MyDynamicFramework' not valid for use in process: mapped file has no cdhash, completely unsigned?

Am I missing some settings? I thought that Embed & Sign should have solved the issue but it didn't. Thanks. It seems that it works if I embed the MyDynamicFramework in my test application as well, even thought that's already embedded into the framework (MyFramework) that I'm using. I don't see why should I do that, isn't that including the same dynamic framework twice?

How can I insert a UISearchBar in the middle of the shortcuts bar displayed above the keyboard on iPad? You insert custom shortcuts in the shortcuts bar using 'someTextField.inputAssistantItem' with 'leadingBarButtonGroups' or 'trailingBarButtonGroups' properties, but it has no 'middleBarButtonGroups'. If I add the search bar as 'inputAccessoryView', like 'someTextField.inputAccessoryView = UISearchBar()' it is added above the shortcuts bar.

I've been running into an issue on Sonoma (currently running 14.0 Beta - 23A5328b). In my app, I have a class derived from NSView that draws an image. Up until now, the image has shown up in the proper location & with the correct orientation based on the overridden value of "isFlipped" along with the value of respectFlipped in drawInRect, but with Sonoma it's not working properly. As an example, in macOS 11.7 (Big Sur), I have my NSView-derived class, and some drawing code like this (I've hard-coded the rectangle's coordinates for ease of testing): [image drawInRect:NSMakeRect(10, 10, 48, 48) fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0 respectFlipped:NO hints:nil]; In Big Sur, here's what I see: isFlipped returns NO & respectFlipped is NO: the image gets drawn near the bottom-left corner of the view & is oriented properly. isFlipped returns NO & respectFlipped is YES: same as case 1 isFlipped returns YES & respectFlipped is NO: same as case 1 isFlipped returns YES & respectFlipped is YES: the image gets drawn near the bottom-left corner & is flipped. In Sonoma, here's what I see: isFlipped returns NO & respectFlipped is NO: the image gets drawn near the bottom-left corner of the view & is oriented properly. isFlipped returns NO & respectFlipped is YES: same as case 1 isFlipped returns YES & respectFlipped is NO: the image gets drawn near the top-left corner & is flipped. isFlipped returns YES & respectFlipped is YES: the image gets drawn near the top-left corner & is oriented properly. The current code uses case 3 - isFlipped returns YES, but respectFlipped is set to NO. As such, the image that was appearing in the bottom-left corner in its correct orientation is now in the top-right corner & is flipped. I'm considering switching to case 1, but other parts of this view rely on isFlipped returning YES, so I'd have to redo a bunch of positioning math that we currently use. Anyway, I'd be interested to know if anyone else has encountered issues with flipped views & drawToRect calls in Sonoma.

A while ago there was documentation published about the apparently upcoming MediaExtension Framework that was announced to be included in macOS 14 (Sonoma). However, when I recently tried to look it up again, I noticed that all documentation about it now leads to "Not found" pages, even though it still appears in search results. https://developer.apple.com/documentation/mediaextension/ Was this accidentally unpublished or will it not be included in macOS 14 and was therefore removed from the documentation?

Hello everyone, I have code in swift that wraps and implements using xcframework the login to the application, I also have files for the bridge that communicate between react native and native ios code, which inherit from RCTEventEmitter: one for declaring the methods in objc and others for implementing them that communicates between My code for the third party xcframework library. I need to take the files above (xcframework, bridges files: objc+ swift ) and my code in swift and export them to a unit that can use it in my project that can also interface with React with the bridge files and other applications in our company. I'm really at a loss as to what is best to use, spm or a framework, is spm good for an objc file and xcframework and will a lib like RCTEventEmitter be needed to import to this unit, or a framework that is scalable, dynamic and can fit? Thanks a lot in advance if you can give me any information about these and how to make this SPM or framework according to my needs? And what is the most correct and best practice?

Hi guys, I’m building an audio unit and I need to add a 3rd party framework. Validating the AU with Logics plugin manager fails saying it could not find the framework. It says it is neither in /System/Library/Frameworks nor under @rpath. Then it was complaining that @ path expansion violates security policy. Logic will still load the plugin fine, if I force it to use it, though, which seems weird. Then I exchanged the @rpath reference in the AudioUnit with install_name_tool. That worked but told me that it had to break code signing. When I re-ran auval, the “not found” errors went away, but it still could not be loaded, supposedly because of the broken signing. Btw, I could only get detailled information about auvals complaints if I ran Logic and thus the scanning process inside the debuugger. If I did the same thing outside the debugger, auval would only say something like 'could not load, result code 0xSomething' but not give me any details. In both cases Logic would still load the plugin if forced to. What should I do here? Cheers and thanks in advance :-)
