Im honestly a bit lost and looking for general pointers. Here is the general flow of my project. I have an Xcode project where I want to return and convert the temperature values accessed from the apple smc and I found a GitHub repo with all the smc key sensors for the M3Pros/Max chips: https://github.com/exelban/stats/issues/1703 basically, I have all these keys stored in an array in obj-c like so: NSArray *smcKeys = @[ @"Tp01", @"Tp05", @"Tp09", @"Tp0D", @"Tp0b", @"Tp0f", @"Tp0j", @"Tp0n",@"Tp0h", @"Tp0L", @"Tp0S", @"Tp0V", @"Tp0z", @"Tp0v", @"Tp17", @"Tp1F", @"Tp1J", @"Tp1p", @"Tp1h", @"Tp1R", ]; I am passing all these keys by passing 'smcKeys' in a regular C code file I have here that is meant to open, close and read the data shown here: #include "smc.h" #include <mach/mach.h> #include <IOKit/IOKitLib.h> #include "smckeys.h" io_connect_t conn; kern_return_t openSMC(void) { kern_return_t result; kern_return_t service; io_iterator_t iterator; service = IOServiceGetMatchingServices(kIOMainPortDefault, IOServiceMatching("AppleSMC"), &iterator); if(service == 0) { printf("error: could not match dictionary"); return 0; } result = IOServiceOpen(service, mach_task_self(), 0, &conn); IOObjectRelease(service); return 0; } kern_return_t closeSMC(void) { return IOServiceClose(conn); } kern_return_t readSMC(char *smcKeys, SMCVal_t *val) { kern_return_t result; uint32_t keyCode = *(uint32_t *)smcKeys; SMCVal_t inputStruct; SMCVal_t outputStruct; inputStruct.datasize = sizeof(SMCVal_t); inputStruct.datatype = 'I' << 24; //a left shift operation. turning the I into an int by shifting the ASCII value 24 bits to the left inputStruct.data[0] = keyCode; result = IOConnectCallStructMethod(conn, 5, &inputStruct, sizeof(SMCVal_t), &outputStruct, (size_t*)&inputStruct.datasize); if (result == kIOReturnSuccess) { if (val -> datasize > 0) { if (val -> datatype == ('f' << 24 | 'l' << 16 | 't' << 8 )) { //bit shifting to from 32bit operation associated with the ASCII charecters'f', 'l', and 't', sets datatype field. double temp = *(double *)val -> data; return temp; } } } return 0.0; } Which I am then then calling the functions from this file in a swift file and converting the values to Fahrenheit but no data is being printed in my console: import IOKit public class getTemperature { public struct SMCVal_t { var datasize: UInt32 var datatype: UInt32 var data: (UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8) } @_silgen_name("openSMC") func openSMC() -> kern_return_t @_silgen_name("closeSMC") func closeSMC() -> kern_return_t @_silgen_name("readSMC") func readSMC(key: UnsafePointer<CChar>?,val: UnsafeMutablePointer<SMCVal_t>) -> kern_return_t func convertAndPrintTempValue(key:UnsafePointer<CChar>?,scale: Character, showTemp: Bool ) -> kern_return_t { let openSM = openSMC() guard openSM == 0 else { print("Failed to open SMC: \(openSM)") return kern_return_t() } let closeSM = closeSMC() guard closeSM == 0 else { print("could not close SMC: \(closeSM)") return IOServiceClose(conn) } func convertAndPrint(val: SMCVal_t) -> Double { if val.datatype == (UInt32("f".utf8.first!) << 24 | UInt32("l".utf8.first!) << 16 | UInt32("t".utf8.first!) << 8) { let extractedTemp = Double(val.data.0) return( extractedTemp * 9.0 / 5.0 + 32.0 ) } return 0.0 } let smcValue = SMCVal_t(datasize: 0, datatype: 0, data: (0,0,0,0,0,0,0,0)) let convertedVal = convertAndPrint(val: smcValue) print("Temperarure:\(convertedVal)F°") return kern_return_t() } } I know this is a lot but I am honestly looking for any tips to fill in any gaps in my knowledge for anyone who's built a similar application meant to extract any sort of data from Mac hardware.

I have a sandboxed app in /Applications. I'm attempting to shoot a problem with LLDB, so I cd to /Applications/app-name/Contents/MacOS and do lldb programname. However, once I fire it off with "r" it dies instantly with: error: process exited with status -1 (lost connection) Should this work? Should I try signing the lldb executable? Thanks!

Because my MacOS app has a user-programmable interface, my coding creates lots of interface elements programmatically. Soon after an update to MacOS 14.3.1, I found some of these element (NSTextFields) did not draw correctly. I had not changed any code but the appearance changed for the worse (the text in the text field did not appear). I then noticed: The problem occurs when I compile in XCode 15.2 (15C500b) Version and run on computer with Sonoma 14.3.1 (23D60) If I instead compile in XCode Version 14.1 (14B47b) on Ventura 13.0.1 (22A400) and copy the app to my computer with Sonoma 14.3.1 (23D60)all works as expected. These results seem to imply XCode 15.2 does not compile correctly? Is this known issue or is there a fix?

In Xcode 15 and 14, I encounter the following error related to float max and min. This occurs within a React Native project, although it seems that React itself is not the cause of the error.

Hi there, i have an macOS app, sandboxed, compatibility 10.13 up to Sonoma, objective-C. I have a dropzone (or alternatively selection with NSOpenPanel) where users can drop files which results in an array of NSURLs. I create bookmarks to securely access them. This worked for years. Now i want to add iCloud support. Everything works good so far. I have methods to check the file status and download the file from icloud if NSURLUbiquitousItemDownloadingStatusKey == NSURLUbiquitousItemDownloadingStatusNotDownloaded Then i listen for the file, once the status key changes to NSURLUbiquitousItemDownloadingStatusCurrent i continue with processing the NSURL and i want to create bookmarkData: [filePathUrl bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope includingResourceValuesForKeys:nil relativeToURL:nil error:&amp;error]]; But this returns the error "Could not open() the item: [1: Operation not permitted]" So i was wondering if downloading the file from iCloud now changed the NSURL itself so the given permissions by dropping do not match the downloaded file? Adding [filePathUrl startAccessingSecurityScopedResource]; didn't change anything. Any help appreciated

I have multiple mobile applications, one developed in React Native and the other in Objective-C and Swift hybrid technology. I use my own system to send push notifications, and these notifications are left encrypted in the Apple queues. However, in any of my applications, I am unable to catch these messages in the code block where I decrypt them. As a result, users see the messages encrypted. While I can deterministically detect this issue on devices experiencing the offload feature from Apple, I've also noticed sporadic occurrences of this issue on devices not utilizing offload. Due to my security policies, I have no chance of sending messages unencrypted. I'm trying to understand why this is happening and need suggestions for a solution. Is there anyone who can help? Additional Information: I use my own system for push notifications. Messages are left encrypted in the Apple queues. I am unable to catch the messages in the code block where I decrypt them in one of the applications. I can deterministically detect the issue on devices experiencing the offload feature. I've noticed sporadic occurrences of this issue on devices not using offload. Due to security policies, I have no chance of sending messages unencrypted. I tried sending without offloading, and the messages arrived unencrypted I searched for a callback handler function on the Apple side - couldn't find one. To ensure notifications were sent correctly, I performed token checks in my database.

I have an Xcode project with an obj-c .c file and a .h file aswell as a .swift file where I am calling functions from those obj-c files with a bridging header but when I build my project I get a duplicate symbols error and Xcode doesn't show where. here is .h header file: #define smc_h #include &lt;stdint.h&gt; #include &lt;mach/mach.h&gt; #include &lt;IOKit/IOKitLib.h&gt; typedef struct { uint32_t datasize; uint32_t datatype; uint8_t data[8]; } SMCVal_t; io_connect_t conn; kern_return_t openSMC(void); kern_return_t closeSMC(void); kern_return_t readSMC(char *key, SMCVal_t *val); double convertToFahrenheit(SMCVal_t *val); #endif /* smc_h */ my .c implementation file: #include "smc.h" kern_return_t openSMC(void) { kern_return_t result; kern_return_t service; io_iterator_t iterator; service = IOServiceGetMatchingServices(kIOMainPortDefault, IOServiceMatching("AppleSMC"), &amp;iterator); if(service == 0) { printf("error: could not match dictionary"); return 0; } result = IOServiceOpen(service, mach_task_self(), 0, &amp;conn); IOObjectRelease(service); return 0; } kern_return_t closeSMC(void) { return IOServiceClose(conn); } kern_return_t readSMC(char *key, SMCVal_t *val) { kern_return_t result; uint32_t keyCode = *(uint32_t *)key; SMCVal_t inputStruct; SMCVal_t outputStruct; inputStruct.datasize = sizeof(SMCVal_t); inputStruct.datatype = 'I' &lt;&lt; 24; //a left shift operation. turning the I into an int by shifting the ASCII value 24 bits to the left inputStruct.data[0] = keyCode; result = IOConnectCallStructMethod(conn, 5, &amp;inputStruct, sizeof(SMCVal_t), &amp;outputStruct, (size_t*)&amp;inputStruct.datasize); if (result == kIOReturnSuccess) { if (val -&gt; datasize &gt; 0) { if (val -&gt; datatype == ('f' &lt;&lt; 24 | 'l' &lt;&lt; 16 | 't' &lt;&lt; 8 )) { //bit shifting to from 32bit operation associated with the ASCII charecters'f', 'l', and 't', sets datatype field. double temp = *(double *)val -&gt; data; return temp; } } } return 0.0; } double convertToFahrenheit(SMCVal_t *val) { if(val -&gt; datatype == ('f' &lt;&lt; 24 | 'l' &lt;&lt; 16 | 't' &lt;&lt; 8 )) { //checking if val-&gt;datatype is equal to the result of the bit-shifting operation. double temp = *(double *)val -&gt; data; return (temp * 9.0 / 5.0) + 32.0; } return 0.0; } And my .swift file where my objc functions are called: import IOKit public class CPUTempCaller { public struct SMCVal_t { var datasize: UInt32 var datatype: UInt32 var data: (UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8) } @_silgen_name("openSMC") func openSMC() -&gt; Int32 @_silgen_name("closeSMC") func closeSMC() -&gt; Int32 @_silgen_name("readSMC") func readSMC(key: UnsafePointer&lt;CChar&gt;?,val: UnsafeMutablePointer&lt;SMCVal_t&gt;) -&gt; kern_return_t @_silgen_name("convertToFahrenheit") func convertToFahrenheit(val: UnsafePointer&lt;SMCVal_t&gt;) -&gt; Double { let openSM = openSMC() guard openSM == 0 else { print("Failed to open SMC: \(openSM)") return 0.0; } let closeSM = closeSMC() guard closeSM == 0 else { print("could not close SMC: \(closeSM)") return 0.0; } func convertAndPrintTempValue(key:UnsafePointer&lt;CChar&gt;?,scale: Character, showTemp: Bool ) -&gt; Double? { var SMCValue = SMCVal_t(datasize: 0, datatype: 0, data:(0,0,0,0,0,0,0,0)) //initializing SMC value if let Key = key { //check if nil.

Hi, i have a daemon service written in Objective-C and C++. i need to detect user change events and reboot my service. I'm using SCDynamicStoreKeyCreateConsoleUser and get notifications for user switch events but not for fast user switch events. is there a way to reliably subscribe to all kinds of user switch events including VNC connection?

I have a swift file where I am calling objective c functions and providing pointers to certain values where needed but im getting the error " : Cannot convert value of type 'Swift.UnsafeMutablePointer<MacStat.SMCVal_t>' to expected argument type 'Swift.UnsafeMutablePointer<__ObjC.SMCVal_t>' " Here is the relevant code block where I am getting the error: var convertRawToFahrenheit: Double = 0.0 withUnsafeMutablePointer(to: &SMCValue) { pointer in convertRawToFahrenheit = convertToFahrenheit(val: pointer) } print(String(format: "Temperature: %0.1f °%c", convertRawToFahrenheit )) return nil } else { print("could not convert temperature and format values in Fahrenheit") return nil } return 0.0; } I already have a bridging header and the path to that header set up so I know the issue Isn't anything that involves my C functions not getting recognized in swift. I will also provide my full code: import IOKit public struct SMCVal_t { var datasize: UInt32 var datatype: UInt32 var data: (UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8) } @_silgen_name("openSMC") func openSMC() -> Int32 @_silgen_name("closeSMC") func closeSMC() -> Int32 @_silgen_name("readSMC") func readSMC(key: UnsafePointer<CChar>?,val: UnsafeMutablePointer<SMCVal_t>) -> kern_return_t func convertAndPrintTempValue(key:UnsafePointer<CChar>?,scale: Character, showTemp: Bool ) -> Double? { let openSM = openSMC() guard openSM == 0 else { print("Failed to open SMC: \(openSM)") return 0.0; } let closeSM = closeSMC() guard closeSM == 0 else { print("could not close SMC: \(closeSM)") return 0.0; } var SMCValue = SMCVal_t(datasize: 0, datatype: 0, data:(0,0,0,0,0,0,0,0)) //initializing SMC value if let key = key { //check if nil.

I am working on an app in Objective C. I added the the StoreKit framework with the logic using swift. everything worked as planned except for when I wanted to access properties and methods from my ObjC ViewController in the swift code. I did everything as is directed in the apple developer documentation, except it didn't work. I kept receiving the following errors; failed to emit precompiled bridging header ViewController.h file not found ( for the import code in the bridging header) I spent a whole day perusing the internet for a solution. Unfortunately, nothing worked. I thought I should try to import other classes from the ObjC into the bridging header. When I imported 3 files the 3rd one took after commenting out the 2 above it. Then I imported the ViewController again and the build was successful. I deleted every imported file above the file that I need to make visible to the swift compiler leaving the empty lines above it. Apparently, I was getting the errors because my import code was on line 4 instead of line 9, although the file is completely empty except for the comments created by Xcode when the file was automatically created. I am not sure why the placement of the line of code holds that much weight when the file is empty? **Can anyone explain to me any technicality that would lead to this issue? **

I have an Xcode project that include a .c file and .h header file. I am getting a duplicate symbol error and I cannot pinpoint what part of my code is the issue or maybe if it's a configuration issue in my Xcode settings or not. Here's my .h header file code with my declarations: #define smc_h #include <stdint.h> #include <mach/mach.h> #include <IOKit/IOKitLib.h> typedef struct { uint32_t datasize; uint32_t datatype; uint8_t data[8]; } SMCVal_t; extern io_connect_t conn; kern_return_t openSMC(void); kern_return_t closeSMC(void); kern_return_t readSMC(char *key, SMCVal_t *val); double convertToFahrenheit(SMCVal_t *val); #endif /* smc_h */ And here is my .c implementation: #include "smc.h" #include <mach/mach.h> #include <IOKit/IOKitLib.h> io_connect_t conn; kern_return_t openSMC(void) { kern_return_t result; kern_return_t service; io_iterator_t iterator; service = IOServiceGetMatchingServices(kIOMainPortDefault, IOServiceMatching("AppleSMC"), &iterator); if(service == 0) { printf("error: could not match dictionary"); return 0; } result = IOServiceOpen(service, mach_task_self(), 0, &conn); IOObjectRelease(service); return 0; } kern_return_t closeSMC(void) { return IOServiceClose(conn); } kern_return_t readSMC(char *key, SMCVal_t *val) { kern_return_t result; uint32_t keyCode = *(uint32_t *)key; SMCVal_t inputStruct; SMCVal_t outputStruct; inputStruct.datasize = sizeof(SMCVal_t); inputStruct.datatype = 'I' << 24; //a left shift operation. turning the I into an int by shifting the ASCII value 24 bits to the left inputStruct.data[0] = keyCode; result = IOConnectCallStructMethod(conn, 5, &inputStruct, sizeof(SMCVal_t), &outputStruct, (size_t*)&inputStruct.datasize); if (result == kIOReturnSuccess) { if (val -> datasize > 0) { if (val -> datatype == ('f' << 24 | 'l' << 16 | 't' << 8 )) { //bit shifting to from 32bit operation associated with the ASCII charecters'f', 'l', and 't', sets datatype field. double temp = *(double *)val -> data; return temp; } } } return 0.0; } double convertToFahrenheit(SMCVal_t *val) { if(val -> datatype == ('f' << 24 | 'l' << 16 | 't' << 8 )) { //checking if val->datatype is equal to the result of the bit-shifting operation. double temp = *(double *)val -> data; return (temp * 9.0 / 5.0) + 32.0; } return 0.0; }

I am new to Objective C and relatively new to iOS development. I have an AVCaptureDevice object at hand and would like to print the maximum supported photo dimensions as provided by activeFormat.supportedMaxPhotoDimensions, using Objective C. I tried the following: for (NSValue *obj in device.activeFormat.supportedMaxPhotoDimensions) { CMVideoDimensions *vd = (__bridge CMVideoDimensions *)obj; NSString *s = [NSString stringWithFormat:@"res=%d:%d", vd->width, vd->height]; //print that string } If I run this code, I get: res=314830880:24994 This is way too high, and there is obviously something I am doing wrong, but I don't know what it could be. According to the information I see on the developer forum, I should get something closer to 4000:3000. I can successfully read device.activeFormat.videoFieldOfView and other fields, so I believe my code is sound overall.

This is a problem that only exists on MacOS 13 (Ventura) and MacOS 14 (Sonoma). On all earlier versions of MacOS, the existing code works well, and has for many years. I am working on an long-running Objective-C MacOS app (non-sandboxed) that uses WKWebView to display a static web page within a "pane" of a larger NSView. By "pane", I mean the WKWebView might be the only view within the encompassing NSView (thereby occupying all of its space), or it might occupy only one rectangle within it, if the NSView is divided into arbitrary rectangles. (Whether or not the WKWebView takes up the entire surrounding rectangle, or just a section of it, seems irrelevant.) The WKWebView is created offscreen at startup time, and later may become visible under user control. I don't need the displayed web page to permit any interactivity with the user other than scrolling, and I disable Javascript on the page using the WKWebViewConfiguration - which appears to work as intended. I therefore have no need for NSTrackingArea either, and am not using it. It does appear that the WKWebView has one NSTrackingArea by default, but it's not mine. I can remove it programmatically, but that does not appear to make any difference. When the WKWebView is visible, the app will instantly crash as soon as the cursor enters its rectangle. The stack trace shows the error: [_NSTrackingAreaCGViewHelper cursorAreas]: unrecognized selector sent to instance The problem here is that the _NSTrackingAreaCGViewHelper method appears to be something within an Apple internal framework - I can't find discussion of it anywhere on the Internet, or in Apple's developer docs. Same for the selector "cursorAreas" - I can't find any information about it at all. So this is starting to feel like a bug somewhere in Apple's internal framework. I can't understand why it's crashing with a message related to NSTrackingArea (or similar objects), when I'm not using tracking at all, but the "unrecognized selector" error is even more disturbing - I'm not calling the method, and certainly can't control the selector. I can't be sure, but this feels like Apple's error. I'd like to know if there might be a way for me to configure WKWebView to not use tracking at all, thereby eliminating the issue entirely, but I can't find a way to do that other than removing the NSTrackingAreas from the WKWebView, but that's not helping either. Can anyone (especially from Apple) offer any guidance? If it's an Apple bug, I would love to know how to work around it - it's a show-stopper for this app. Thanks in advance...

I have a tvOS project contains an App target and 3 static libraries: EntryPoint – Static library that contains main , AppDelegate and SceneDelegate Experience – Static library containing my UI elements AppTarget – executable built using above two libraries I have a class "SelectionTable" which subclasses UITableView in Experience target : import UIKit class SelectionTable : UITableView { private var vDataSrc:[String]! func SetDataSrc (_ pDataSrc:[String]) { self.vDataSrc = pDataSrc } func UpdateDataSrc (_ pStringList:[String]) { self.vDataSrc += pStringList } func GetDataSrc () -> [String] { return self.vDataSrc } } I am not using this class anywhere and still i am getting these errors when i build my AppTarget: Cannot find interface declaration for 'UITableView', superclass of 'SelectionTable' Expected a type These above error are coming in generated header file "Experience-Swift.h".

We are getting many crash reports from users that just updated to Sonoma 14.3 on arm64 macs. We can reproduce these types of crashes on arm64 14.3 machines only (not Intel 14.3, other versions of macOS, etc).

Hello, I want to dynamically update the values of the LSApplicationQueriesSchemes key in the info.plist file within this project. Is this possible? What is Apple's stance on this matter in terms of security?

I have been having issue with tableview changing its content offset when disabling the scroll on the button click. Is this the expected behaviour? This is with Xcode 15 and iOS 17.
