We're distributing an XCFramework to a customer to create their own apps. With the new XCFramework signing requirements, we have a question with regards the way how to implement it. We're using a few of the frameworks on the list https://developer.apple.com/support/third-party-SDK-requirements/ including [AFNetworking], as a dependencies for our framework. We are building those frameworks from source code and not using any binaries provided by any third-party. We also modify the open source code, so that it is different from the original open source code in a way so that it won't lead to runtime conflicts in case the customers is including similar frameworks in their application. We're using those derivatives of the open source frameworks as a statically linked libraries to our SDK. Questions: Do we need to sign the third party frameworks of which we have cloned source code and using it within our SDK Framework? Is it required that the XCFramework built this way is signed when it is delivered to a third party and they use it in their app?

I have apps using CMAltimeter to get sensor data, but recently they stop working with iOS 17.4, it is not release but some user running beta version, the is no access to the sensor data anymore (altitude and barometer). Some user report they can fix it by manual the "Motion & Fitness" permission but it only appear on some device. Report has been sent to Apple but I post here to find the solution to fix it.

Since yesterday (03/22/24) we are unable to upload new or existing builds to AppStoreConnect. We get the following error - “Error ITMS-90432 Unexpected file found in Frameworks. MyApp.app/Frameworks/Configurations” file is in the Frameworks directory, but the Swift runtime libraries are the only files permitted in that directory. Please remove this file and upload a new build. (ID: 57e219ea-d27e-465d-9e9b-ec41d3a0b1f7). We have tried rebuilding targerts with no changes for Builds that use to upload ok and they now get the same error too. Is this an appstoreconnect bug? If not where is the Frameworks directory and how do we remove the file?

Hey! TLDR: How Health app knows the new menstruation cycle started? The API Adding .menstrualFlow (HKCategoryValueMenstrualFlow) samples require HKMetadataKeyMenstrualCycleStart: Bool parameter. It's fairly simple for the consecutive days - the first sample includes true, the rest false. The problem What about more complex scenarios like: 3 days of unspecified samples, then 2 days of none samples, and unspecified sample again. Should it be marked as the new cycle start? I don't want to prompt the user to confirm the new menstruation cycle. Observations I noticed Health app performs some logic under the hood. For instance, when I marked 5 days in a row unspecified, then left 6 days in a row empty, then selected unspecified again, I got 2 menstruation cycles (11 days ago and today). But when I changed the number of the days I marked as unspecified before the gap, or the length of the gap, or edited the cycles further in the past, I ended up having just 1 menstruation cycle. I guess Health app takes into consideration: previous menstruation length, gap length, average cycle length. But what is the exact math here? I don't want to ruin the user's statistics 💚 I found in the user guide this info about the fertility: The fertile window will be the six days you're most likely to be fertile, based on data that you’ve logged about your period or a positive ovulation test result. The fertile window prediction is based on a traditional calendar method. The fertile window is calculated by subtracting 13 days (the luteal phase) from the estimated next cycle start date. So I think something similar might be going on here. Thanks in advance!

I'm developing a (XC) 3rd party framework, but the framework doesn't use any privacy access API as listed in listed in this document. Do I still need to include the PrivacyManifest.xcprivacy file which will have empty content into the framework?

Per my understanding of the DispatchQueue docs, and various WWDC videos on the matter, if one creates a queue in the following manner: let q = DisqpatchQueue( label: "my-q", qos: .utility, target: .global(qos: .userInteractive) ) then one should expect work items submitted via async() to effectively run at userInteractive QoS, as the target queue should provide a 'floor' on the effective QoS value (assuming no additional rules are in play, e.g. higher priority items have been enqueued, submitted work items enforce QoS, etc). In practice, however, this particular formulation does not appear to function that way, and the 'resolved' QoS value seems to be utility, contrary to what the potentially relevant documentation suggests. This behavior appears to be inconsistent with other permutations of queue construction, which makes it even more surprising. Here's some sample code I was experimenting with to check the behavior of queues created in various ways that I would expect to function analogously (in regards to the derived QoS value for the threads executing their work items): func test_qos_permutations() { // q1 let utilTargetingGlobalUIQ = DispatchQueue( label: "qos:util tgt:globalUI", qos: .utility, target: .global(qos: .userInitiated) ) let customUITargetQ = DispatchQueue( label: "custom tgt, qos: unspec, tgt:globalUI", target: .global(qos: .userInitiated) ) // q2 let utilTargetingCustomSerialUIQ = DispatchQueue( label: "qos:util tgt:customSerialUI", qos: .utility, target: customUITargetQ ) // q3 let utilDelayedTargetingGlobalUIQ = DispatchQueue( label: "qos:util tgt:globalUI-delayed", qos: .utility, attributes: .initiallyInactive ) utilDelayedTargetingGlobalUIQ.setTarget(queue: .global(qos: .userInitiated)) utilDelayedTargetingGlobalUIQ.activate() let queues = [ utilTargetingGlobalUIQ, utilTargetingCustomSerialUIQ, utilDelayedTargetingGlobalUIQ, ] for q in queues { q.async { Thread.current.name = q.label let threadQos = qos_class_self() print(""" q: \(q.label) orig qosClass: \(q.qos.qosClass) thread qosClass: \(DispatchQoS.QoSClass(rawValue: threadQos)!) """) } } } Running this, I get the following output: q: qos:util tgt:customSerialUI orig qosClass: utility thread qosClass: userInitiated q: qos:util tgt:globalUI-delayed orig qosClass: utility thread qosClass: userInitiated q: qos:util tgt:globalUI orig qosClass: utility thread qosClass: utility This test suggests that constructing a queue with an explicit qos parameter and targeting a global queue of nominally 'higher' QoS does not result in a queue that runs its items at the target's QoS. Perhaps most surprisingly is that if the target queue is set after the queue was initialized, you do get the expected 'QoS floor' behavior. Is this behavior expected, or possibly a bug?

Hello, Which API can be used to programatically fetch the ID of user who installed/paid the app? This is useful if an app has to create a path hierarchy for different users who have installed/paid the app, for instance, /AppName//user_files, how to get the uniqueUserID, and also, to get the information about which user these files belong to based on this uniqueUserID. App is using Swift, SwiftUI. Thanks.

Please help me understand the phrasing from Apple's articles about this topic. Of course, I am referring to the SDKs from the official list, as only those are affected by the new regulations. 1, https://developer.apple.com/support/third-party-SDK-requirements/ Starting in spring 2024, you must include the privacy manifest for any SDK listed below when you submit new apps in App Store Connect that include those SDKs, or when you submit an app update that adds one of the listed SDKs as part of the update. That states 2 cases in which fresh SDK versions are needed, containing privacy information: If you submit a completely new app If your app update contains a framework which was not present in the previous version of the app So, according to my understanding, if I create an app update, which does not contain any new SDKs, only the ones that I have been using for a while now, I can keep using these older SKD versions. And it is not mandatory to update them to newer versions. Does Apple state anywhere that we have to update every SDK from the list this spring in every case? Because that would contradict what I quoted from the article. 2, https://developer.apple.com/news/?id=3d8a9yyh And if you add a new third-party SDK that’s on the list of commonly used third-party SDKs, these API, privacy manifest, and signature requirements will apply to that SDK. Again, this states that you have to use a fresh version of an SDK in case you add it newly to your app. This seems to reinforce my point that if a 3rd party SDK was already used in previous app versions, the new requirements do not apply to that SDK and I can keep using its older release which does not have its own privacy manifest file. My main concern here is that there are many 3rd party SDKs from the list that we already use in our projects, and it would be a huge effort if my team had to update all those SDKs in every project by May. But if I'm right, it is not mandatory for us. (Of course, it would be wise to update the SDKs every now and then, but that's not the point here.) Can anybody confirm whether my understanding is correct? Maybe link some proof if I'm not right? It would be nice to have a reply from someone working at Apple, to have a reliable answer.

Hi everyone, I'm currently working on a project that involves using the Network framework on macOS 10.15 and iOS 12. While implementing error handling for my network connections, I encountered a warning about the conformance of 'NWError' to 'CustomNSError', which is only available in macOS 13.3 or newer. Here's the warning message I received while compiling the code: Warning: conformance of 'NWError' to 'CustomNSError' is only available in macOS 13.3 or newer self.vConnection = try NWConnection (to: self.vBaseSocketProperties!.uEndpoint!, using: self.vBaseSocketProperties!.uParamters!) self.vConnection?.stateUpdateHandler = { connectionState in switch connectionState { case .failed(let err): error_code = err.errorCode //Below all the other cases are also handled. }

Hi there, I'm working on an app that contains a mini system monitoring utility. I would like to list the top CPU-using processes. As Quinn “The Eskimo!” has repeatedly cautioned, relying on private frameworks is just begging for maintenance effort in the future. Ideally, I want to go through public headers/frameworks. I've gone to great lengths to try to find this information myself, and at this point I'm just struggling. I detail my research below. Any pointers in the right direction would be much appreciated! Attempts Libproc First I looked at libproc. Using proc_pidinfo with PROC_PIDTHREADINFO, I'm able to get each thread of an app, with its associated CPU usage percentage. Summing these, I could get the total for an app. Unfortunately, this has two downsides: Listing a table of processes now takes O(proces_count) rather than just O(process_count), and causes way more syscalls to be made It doesn't work for processes owned by other users. Perhaps running as root could alleviate that, but that would involve making a priviliedged helper akin to the existing sysmond that Activity Monitor.app uses. I'm a little scared of that, because I don't want to put my users at risk. Sysctl Using the keys [CTL_KERN, KERN_PROC, KERN_PROC_PID, someProcessID], I'm able to get a kinfo_proc - https://github.com/apple-opensource/xnu/blob/24525736ba5b8a67ce3a8a017ced469abe101ad5/bsd/sys/sysctl.h#L750-L776 instance. Accessing its .kp_proc - https://github.com/apple-opensource/xnu/blob/24525736ba5b8a67ce3a8a017ced469abe101ad5/bsd/sys/proc.h#L96-L150.p_pctcpu - https://github.com/apple-opensource/xnu/blob/24525736ba5b8a67ce3a8a017ced469abe101ad5/bsd/sys/proc.h#L123 looked really promising, but that value is always zero. Digging deeper, I found the kernel code that fills this struct in (fill_user64_externproc - https://github.com/apple-opensource/xnu/blob/c76cff20e09b8d61688d1c3dfb8cc855cccb93ad/bsd/kern/kern_sysctl.c#L1121-L1168). The assignment of p_pctcpu - https://github.com/apple-opensource/xnu/blob/c76cff20e09b8d61688d1c3dfb8cc855cccb93ad/bsd/kern/kern_sysctl.c#L1149 is in a conditional region, relying on the _PROC_HAS_SCHEDINFO_ flag. Disassembling the kernel on my mac, I could confirm that the assignment of that field never happens (thus _PROC_HAS_SCHEDINFO_ wasn't set during compilation, and the value will always stay zero) Reverse engineering Activity Monitor.app Activity Monitor.app makes proc_info and sysctl system calls, but from looking at the disassembly, it doesn't look like that's where its CPU figures come from. From what I can tell, it's using private functions from /usr/lib/libsysmon.dylib. That's a user library which wraps an XPC connection to sysmond (/usr/libexec/sysmond), allowing you to create requests (sysmon_request_create), add specific attributes you want to retrieve (sysmon_request_add_attribute), and then functions to query that data out (sysmon_row_get_value). Getting the data "striaght from the horses mouth" like this sounds ideal. But unfortunately, the only documentation/usage I can find of sysmond is from bug databases demonstrating a privilege escalation vulnerability lol. There are some partial reverse engineered header files floating around, but they're incomplete, and have the usual fragility/upkeep issues associated with using private APIs. On one hand, I don't want to depend on a private API, because that takes a lot of time to reverse engineer, keep up with changes, etc. On the other, making my own similar privileged helper would be duplicating effort, and expose a bigger attack surface. Needless to say, I have no confidence in being able to make a safer privileged helper than Apple's engineers lol Reverse engineering iStat Menus Looks like they're using proc_pid_rusage - https://github.com/apple-opensource/xnu/blob/24525736ba5b8a67ce3a8a017ced469abe101ad5/libsyscall/wrappers/libproc/libproc.h#L103-L108 . However, I don't know how to convert the cpu_*_time fields of the resulting struct rusage_info_v4 - https://github.com/apple-opensource/xnu/blob/24525736ba5b8a67ce3a8a017ced469abe101ad5/bsd/sys/resource.h#L306-L343 to compute a "simple" percentage. Even if I came up with some formula that produces plausible looking results, I have no real guarantee it's correct or equivalent to what Activity Monitor shows.

Suppose I have some third party frameworks integrated in an application. From May inwards, its mandatory to have privacy manifest for all the tracking APIs. But if the third party library doesnt have any plans to integrate the third party framework, how should we proceed to avoid rejection from the app store?

I have developed a framework for my customer, thats a swift dyanmic framework. For code modularization i have divided this framework features in to multiple static libraries as shown in the diagram below. Currently we have on main swift dynamnic framework and it contains 2 static libraries too. Also the first static library here in turn nested with another static library, Key points to note here is My static libraries contains other third party iOS frameworks My static libraries using CoccoaPods as the dependency for Alarmofire at the moment. My questios are Is there any problem in the current architecture , because i heard nested libraries are not supported in iOS . but since we dont have frameworks nested here, all of our second level frameworks are static libraries only. What are link/libary search path guidance we needed to take care to make a successful build.

Our team uses a static library (.a) consisting of C and C++. Our team is developing static libraries internally and not sharing them to the outside. Should we still provide 'Privacy Manifest' in this case?? I added the contents of our team's static library (.a) to the app's 'Privacy Manifest' and there was no problem. Nevertheless, if I have to add it separately to the static library (.a), should I create a new framework project itself and not use the .a? Or can I just create a new framework and wrap the .a file??

Hello, maybe anyone know anything about HCE (Host card emulation) feature on iOS? As far as I read, it's not possible to achieve this functionality on iOS, but maybe there are plans to implement that? Or maybe it's clear that it wont be allowed to be used at all? Thanks:)

Hi, we are currently implementing below method for a quick POC in iOS (Xcode 15.3/macOS Sonoma 14.0): func startQUICConnection() async { // Set the initial stream to bidirectional. options.direction = .bidirectional self.mainConn?.stateUpdateHandler = { [weak self] state in print("Main Connection State: \(state)") switch state { case .ready: print("Ready...") default: break } } // Don't forget to start the connection. self.mainConn?.start(queue: self.queue) } This is what we have in the initializer of the class: parameters = NWParameters(quic: options) mainConn = NWConnection(to: endpoint, using: parameters) These are the class's properties: let endpoint = NWEndpoint.hostPort(host: "0.0.0.0", port: .init(integerLiteral: 6667)) let options = NWProtocolQUIC.Options(alpn: ["echo"]) let queue = DispatchQueue(label: "quic", qos: .userInteractive) var mainConn: NWConnection? = nil let parameters: NWParameters! As per the logs, we never get to the .ready state for the NWConnection. Logs: nw_path_evaluator_create_flow_inner failed NECP_CLIENT_ACTION_ADD_FLOW (null) evaluator parameters: quic, attach protocol listener, attribution: developer, context: Default Network Context (private), proc: 022B7C28-0271-3628-8E5E-26B590B50E5B nw_path_evaluator_create_flow_inner NECP_CLIENT_ACTION_ADD_FLOW 8FEBF750-979D-437F-B4A8-FB71F4C5A882 [22: Invalid argument] nw_endpoint_flow_setup_channel [C2 0.0.0.0:6667 in_progress channel-flow (satisfied (Path is satisfied), interface: en0[802.11], ipv4, ipv6, dns, uses wifi)] failed to request add nexus flow Main Connection State: preparing Main Connection State: waiting(POSIXErrorCode(rawValue: 22): Invalid argument) We're running a local server using proxygen on port 6667. It connects with the proxygen client though... Have tried several thing but results are the same.

When distributing a 3rd party SDK as an XCFramework in order to include the privacy manifest to the bundle you need to include the resources key in the target configuration to point to the correct file, for example: resources: [.process("Resources/PrivacyInfo.xcprivacy")] However, when distributing the xcframework as a binaryTarget resources is not available. How can I include my privacy manifest when configuring Package.swift ?

In https://developer.apple.com/support/third-party-SDK-requirements/ it says "Signatures are also required in these cases where the listed SDKs are used as binary dependencies. " As I am clueless regarding the technicalities of how sdks are added to a host app, the term binary dependency means nothing to me. For reference, our app uses Cocoapods to install all of the sdks.

I have been working with a framework to add multiplayer support to my app. The app runs on test devices, simulators, and archives perfectly fine and the app is fine without the framework. But when I go to distribute the app, I see get this error related to the multiplayer framework I have added. I have tried updating the minimumOSVersion to 9.0, 10.0, 12.0, and 13.0 everywhere (info.plist, deployment info, build settings, etc) and they all match with each build/archive but no matter what I can't get fix this error. This error only shows up when I go to distribute the app to the store. Any ideas on what to try or how to fix this issue? I've attached a screenshot of the issue below.
