I have a C file for accessing the apple smc and I have the corresponding header file with my declarations in it but when I build my Xcode project I get the error: "ld: Undefined symbols: _getTemperature, referenced from: _main in getsmc.o clang: error: linker comm" #include <stdio.h> #include <IOKit/IOKitLib.h> typedef struct { uint32_t datasize; uint32_t datatype; uint8_t data[32]; } SMCVal_t; 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); } double getTemperature(char *key); 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 )) { float temp = *(float *)val -> data; return temp; } } } return 0.0; } int main(void) { kern_return_t result; result = openSMC(); if(result == kIOReturnSuccess) { double temp = getTemperature("TC0P"); printf("temp: %.2f\n", temp); result = closeSMC(); } return 0; }

Im trying to create a function to retrieve my Mac's RAM usage but I get alerts saying essentially that my 'scanDouble' and 'scanCharecters(from:into:)' methods have been depreciated and Xcode also throw me these alerts if I compile this code. what are the newer alternatives to these methods? import Foundation class RAMUsage { let processInfo = ProcessInfo.processInfo func getRAM() { let physicalMemory = processInfo.physicalMemory let formatter = ByteCountFormatter() formatter.countStyle = .memory let formattedMemoryUsage = formatter.string(fromByteCount: Int64(physicalMemory)) parseAndPrint(formattedMemoryUsage: formattedMemoryUsage) } func parseAndPrint(formattedMemoryUsage: String) { print("Formatted RAM usage: \(formattedMemoryUsage)") if let gigsOfRAM = parseFormattedRAMUsage(formattedUsage: formattedMemoryUsage) { print("RAM Usage in Gigabytes: \(gigsOfRAM) GB") } else { print("Could not retrieve or parse RAM usage") } } func parseFormattedRAMUsage(formattedUsage: String) -> Double? { let scanner = Scanner(string: formattedUsage) var value: Double = 0.0 var unit: NSString? if scanner.scanDouble(&value) { scanner.scanCharacters(from: .letters, into: &unit) if let unitString = unit as String?, unitString.lowercased() == "GB" { print("Parsed RAM Usage: \(value) GB") return value } else { print("could not parse and return value") } } return nil } }

0 I am building a simple macOS menu bar app in swift that displays my machine's CPU temperature and I'm just testing out my function to make sure it can retrieve the temp and display it in the Xcode terminal but instead my error handler messages are triggered indicating an issue retrieving my machines CPU temp data "CPU temp °F could not be retrieved temps couldnot be displayed" import Cocoa import IOKit import IOKit.ps class CPUTempWithServiceMatching { static func getCPUTemp() -> Double? { let dictionaryMatching = IOServiceMatching("AppleSMC") var service = IOServiceGetMatchingService(kIOMainPortDefault, dictionaryMatching) var temp = "0.0" if service != 0 { let key = "TC0P" //thermal zone zero proxy if let result = IORegistryEntryCreateCFProperty(service, key as CFString, kCFAllocatorDefault, 0 ) { temp = (result.takeUnretainedValue() as!

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.

This is my first Xcode application, I'm building a simple MacOS chatbox application that uses python scrips, PythonKit, and swift to handle serverSide operations and accessing open's api and is meant to trigger these two methods I have in a function called executeProcess() that is meant to invoke other functions in another file when a question is types in the text field and the 'enter' key on a keyboard is hit via the onCommit function, however im getting no console output. here is my relevant code from my contentView.swift file I can provide more code from other files if needed.(I will just be showing the non SwiftUI specific code here) import Cocoa import Foundation import PythonKit import AppKit protocol runPyRunnable { func runPyServer(completion: @escaping(String) -> Void) func sendRequest(userInput: String, completion: @escaping(String) -> Void) } func runPyServer() -> String { print("server run") return "server run" } struct MyPyTypePlaceHolder: runPyRunnable { func runPyServer(completion: @escaping(String) -> Void) { } func sendRequest(userInput: String, completion: @escaping (String) -> Void) { } } struct ContentView: View { var ViewController: runPyRunnable? = MyPyTypePlaceHolder() as? runPyRunnable @State private var text: String = "" @State private var filePath = "" @State private var inputText = "" var body: some View { makeContent() .onAppear{ NSApp.mainWindow?.makeFirstResponder(NSApp.mainWindow?.contentView) } } ZStack { Spacer() TextField("Ask Mac GPT...", text: $inputText, onCommit: { executeProcess(withInput: inputText) { response in print(response) } }) .font(Font.custom("Futura", size: 17.4)) .padding(.horizontal, 25) .padding(.vertical, 15) .background(Color.white) .cornerRadius(29) .overlay( RoundedRectangle(cornerRadius: 27.9).stroke(Color.gray, lineWidth: 1.0) ) .offset(y: -200) .padding(.horizontal, 35) } } func executeProcess(withInput input: String, completion: @escaping (String) -> Void ) { DispatchQueue.global().async { DispatchQueue.main.async { guard !input.isEmpty else { print("TextField is empty, enter input in the text field") return } if let myPyTypeInstance = self.ViewController { myPyTypeInstance.runPyServer { responseFromRunPyServer in myPyTypeInstance.sendRequest(userInput: input) { responseFromSendRequest in completion(responseFromSendRequest) } } } } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } }

Im getting a scoping error in the default App.swift file of my Xcode project and ive done everything to try to solve the issue, my ContentView struct is at the top level, ive cleaned the build folder a hundred times, restarted Xcode, cleared the derived data folder for nothing to happen. Here is my ContentView.swift file below. protocol runPyAndSendRequestRunnable { func runPyServer() -> String func sendRequest(inputText: String, completion: @escaping(String) -> Void) } func runPyServer() -> String { print("server run") return "server run" } func sendRequest() -> String { print("request sent") return "request sent" } struct MyPyType: runPyAndSendRequestRunnable { func runPyServer() -> String { return "server started" } func sendRequest(inputText: String,completion: @escaping(String) ->Void) { let userInput = inputText guard let url = URL(string:"http://localhost:8080/MacGPT") else { completion("Error: failed to obtain url") return } } struct ContentView: View { var viewController: runPyAndSendRequestRunnable? = MyPyType() @State private var text: String = "" @State private var filePath = "" @State private var inputText = "" var body: some View { makeContent() .onAppear{ NSApp.mainWindow?.makeFirstResponder(NSApp.mainWindow?.contentView) } } func makeContent() -> some View { ScrollView { HStack { VStack { VStack(alignment: .center, spacing: 200) { makeGlobeImage() makeSecondLogo() makeTitle() makeSubtitle() makeTextFieldAndEnter() } .frame(maxWidth: .infinity, maxHeight: .infinity) } .frame(maxWidth: .infinity) } } .background(Color.white.opacity(0.9)) .cornerRadius(12) .padding(.horizontal, 57) .padding(.bottom, 80) .frame(minWidth: 1600, minHeight: 1050) .background(Color.white.opacity(0.1)) .cornerRadius(12) } func makeGlobeImage() -> some View { Image(systemName: "globe") .foregroundColor(.blue) .font(.system(size: 40)) .offset(y: 348) .offset(x: -240) } func makeSecondLogo() -> some View { Image("second Logo") .resizable() .scaledToFit() .frame(width: 90, height: 90) .offset(x: 185) .offset(y: 78) } func makeTitle() -> some View { Text("Mac GPT") .font(Font.custom("Futura", size: 77)) .foregroundColor(Color.black) .padding(2.15) .overlay(RoundedRectangle(cornerRadius: 20).stroke(Color.gray, lineWidth: 1.0)) .offset(x: -37) .offset(y: -221) } func makeSubtitle() -> some View { VStack { Spacer() Text("Access the power of AI right from your Mac's homescreen, just for Mac.") .font(Font.custom("Futura", size: 18.6)) .fontWeight(.bold) .padding(.vertical, 11) } .offset(y: -20) .offset(x: -40) } func makeTextFieldAndEnter() -> some View { ZStack { Spacer() TextField("Ask Mac GPT...", text: $inputText, onCommit: { executeProcess(withInput: inputText) { response in print(response) } }) .font(Font.custom("Futura", size: 17.4)) .padding(.horizontal, 25) .padding(.vertical, 15) .background(Color.white) .cornerRadius(29) .overlay( RoundedRectangle(cornerRadius: 27.9).stroke(Color.gray, lineWidth: 1.0) ) .offset(y: -200) .padding(.horizontal, 35) } } func executeProcess(withInput input: String, completion: @escaping (String) -> Void ) { DispatchQueue.global().async { DispatchQueue.main.async { guard !input.isEmpty else { print("TextField is empty, enter input in the text field") return } self.viewController?.runPyServer() // add closures self.viewController?.sendRequest(inputText: input) { response in completion(response) } } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } } } -code`

Im newer to Swift and Swift UI but im building a simple ai powered chatbox but the button that I have in the UI, when I try to move it back into position using the X,Y offset modifiers, the button gets partially hidden in the body of the UI as can be seen in the bottom right of the picture provided. func makeTextFieldAndButton() -> some View { HStack { Spacer() TextField("Ask Mac GPT...", text: $text) .font(Font.custom("Futura", size: 17.4)) .fontWeight(.bold) .padding(.horizontal, 25) .padding(.vertical, 15) .background(Color.white) .cornerRadius(29) .overlay( RoundedRectangle(cornerRadius: 27.9).stroke(Color.gray, lineWidth: 1.2) ) .offset(y: -120) Button(action: { let process = Process() process.executableURL = URL(fileURLWithPath: "/usr/bin/swift") process.arguments = ["/Users/alexhaidar/Documents/Developer/Mac GPT/serverSide.swift", filePath] try? process.run() }) { ZStack{ Spacer() Image(systemName: "arrow.up.circle.fill") .foregroundColor(Color.blue) .font(Font.system(size: 40)) .buttonStyle(PlainButtonStyle()) .padding(.top) .offset(y: max(-12, -120 + (text.isEmpty ? -10 : 0))) .offset(x: max(-21, text.isEmpty ? -21 : 0)) } } .overlay( RoundedRectangle(cornerRadius: 27.9) .stroke(Color.clear, lineWidth: 1.2) ) .background(Color.clear) .offset(x: 21) } } }

I’m fairly new to Xcode and swift. I’m building my first application. It’s a simple chat box GUI in swift that uses ChatGPT via openai's api that I've imported into my backend python program. I want to use my python program to be able to send and receive requests in the SwiftUI chat-box GUI.
