Im using Notions API to print out some data from one of my own pages in notion and im using URLSession to make the request then parsing the unwrapped data but nothing is being returned to my console and I know my endpoint and API key is correct. I've gone through the notion API documentation can't can't seem to find anything in it that I am not doing or doing wrong. Ill provide my code as well as the documentation I've been consulting: https://developers.notion.com/reference/intro import Foundation struct Page: Codable { let id: String let title: String } let endpoint = URL(string: "https://api.notion.com/v1/pages/8efc0ca3d9cc44fbb1f34383b794b817") let apiKey = "… redacted …" let session = URLSession.shared func makeRequest() { if let endpoint = endpoint { let task = URLSession.shared.dataTask(with: endpoint) { data, response, error in if let taskError = error { print("could not establish url request:\(taskError)") return } if let unwrapData = data { //safely unwrapping the data value using if let do { let decoder = JSONDecoder() //JSONDecoder method to decode api data, let codeUnwrappedData = try decoder.decode(Page.self,from: unwrapData) //type: specifies its a struct, from: passes the data parmeter that contains the api data to be decoded } catch { print("could not parse json data") } } if let httpResponse = response as? HTTPURLResponse { if httpResponse.statusCode == 200 { if let apiData = data { print(String(data: apiData, encoding: .utf8)!) } } else { print("unsuccessful http response:\(httpResponse)") } makeRequest() } } task.resume() } }

I have an async function where im using the withUnsafeContinuation method and closure but for some reason Xcode is not letting me pass either 'error' or 'Error' for continuation.resume(throwing:). I get the error "Cannot convert value of type 'any Error'" public func parseResponseData(data: Data) async throws -> TextResult { return try await withUnsafeContinuation { continuation in Task { do { let decoder = JSONDecoder() let result = try await decoder.decode(TextResult.self, from: data) continuation.resume(returning: result) } catch { continuation.resume(throwing: error) } } } }

I have some c code that returns memory usage of a current task on my machine and recently redacted it to use the proc_getallinfio struct so I can instead retrieve systemwide memory usage. im calling that code in swift however im getting the error "Initializer 'init(_:)' requires that 'proc_taskallinfo' conform to 'BinaryInteger'" and im not sure what the appropriate field is to pass that works with proc_getallinfo struct. resident_size does not work in this context. import IOKit import Foundation @_silgen_name("kernMem") func kernMem(storeMemData: UnsafeMutablePointer <proc_taskallinfo>) -> kern_return_t @main struct MacStatAppApp: App { @State public var printMemory: String = "" //dynamic state object to store data that will be passed to swiftUI var body: some Scene { WindowGroup { ContentView(printMemory: $printMemory) //binding for printMemory to pass data to contentview .onAppear { var storeMemData = proc_taskallinfo() //define pointer let result = kernMem(storeMemData: &storeMemData) if result == KERN_SUCCESS { let memoryUsage = Double(storeMemData) / (1024.0 * 1024.0 * 1024.0) //conversion for GB, 1024 to the power of 3 print(String(format: "memory usage: %.2f GB", memoryUsage)) } else { print("failed to obtain memory usage data:\(result)") } } } } }

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 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.

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.

Im creating a simple chatbox using an api caller library I created and imported but it looks like Xcode is not recognizing the modules as I get multiple "no member" errors for the 'ChatClient' module. `import SwiftUI import openaiLibrary final class ViewModel: ObservableObject { private var openAI: openaiLibrary.ChatClient init(apiKey: String) { let config = openaiLibrary.ChatClient.OpenAIEndpointProvider.makeDefaultKey(api_key: apiKey, endpointProvider: openaiLibrary.ChatClient.OpenAIEndpointProvider()) self.openAI = openaiLibrary.ChatClient(apiKey: apiKey, openaiEndpoint: config.baseURL) } public func sendAIRequest(with search: String, completion: @escaping(Result<String,Error>) -> Void) { openAI?.sendCompletion(with: search) { result in switch result { case .success(let response): if let text = response.choices.first?.text { completion(.success(text)) } else { completion(.failure(NSError(domain: "error", code: 1, userInfo: [NSLocalizedDescriptionKey: "No response found"]))) } case .failure(let error): completion(.failure(error)) } } } struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .padding() } } #Preview { ContentView() } } ` I can also provide my source code for my api caller that my openaiLibrary package dependency uses to make sure everything is defined correctly so that Xcode recognizes everything, due to character constraints I wasn't able to fit it in this post.

in anticipation for the action button that will be coming on the iphone 15pro, am I able to build in functionality and support that takes advantage of the action button for my app in Xcode? I know there are the few 3rd party apps for watchOS that have built in support for the action button on the Apple Watch ultra but I wanted to get more information on this from other developers.
