Do I really have to reset position and size of SKSpriteNodes with every rotation between landscape and portrait layout?? I've done that and it works .. but this seems to be overkill that the writers of Xcode internally compensated for .. vs. having the individual programmer having to do it. I have a getGameParms() which resets positions based on: #if os(iOS) && !targetEnvironment(macCatalyst) func getGameParms() { let roomRect = UIScreen.main.bounds roomWidth = roomRect.width * roomScale roomHeight = roomRect.height * roomScale if (thisSceneName == "GameScene") { if UIDevice.current.orientation.isLandscape { // changes here } else { // changes } } // if (thisSceneName == "GameScene") } // getGameParms #elseif os(tvOS) func getGameParms() { let roomRect = UIScreen.main.bounds roomWidth = roomRect.width * roomScale roomHeight = roomRect.height * roomScale if (thisSceneName == "GameScene") { // other changes here } } // getGameParms #endif Again, the burdensome changes are done .. but are they really necessary? As an alternative, I have called getGameParms() just once within my viewDidLoad() and the results are not correct. For example, I place one SKSpriteNode at the very bottom of the UIScreen and it does not stay there with UIDevice rotation. I also size it horizontally such that it expands to the full width of the UIScreen. Rotation destroys that. if getGameParms() is called only once as just described. Some explanation as to why would be appreciated.

Where can I find documentation, example projects, or video tutorials on how to work with Core Video and Metal?

So I am creating an ObjC framework which has mix of ObjC and Swift code: UtilitiesFramework. Here is my StringUtilities class in Swift: @objc public class StringUtilities: NSObject { } I am accessing StringUtilities class in Utilities which is an ObjC class. Here is Utilities.h which is returning StringUtilities and has a forward class declaration for same: @class StringUtilities; // Forward Declaration @interface Utilities: NSObject - (StringUtilities *)stringUtilities; @end Here is Utilities.m which imports generated swift header file: #import <UtilitiesFramework/UtilitiesFramework-Swift.h> // This should provide concrete implementation of StringUtilities @implementation Utilities - (StringUtilities *)stringUtilities { return [StringUtilities new]; } @end I am exposing Utilites.h file to Swift through module.modulemap: module PrivateObjC { header "Utilities.h" } I have set the import path accurately in build settings as: $(SRCROOT)/$(PRODUCT_NAME) Now when I try to access Utilities class in some other swift class it just compiles fine: import PrivateObjC class SomeOperations { func doSomething() { _ = Utilities() // This compiles fine } However when I try to access the StringUtilities through its method, it gives compilation error: import PrivateObjC class SomeOperations { func doSomething() { _ = Utilities().stringUtilities() // This gives compilation error } Here are the errors: value of type Utilities has no member stringUtilities: _ = Utilities().stringUtilities() note: method stringUtilities not imported - (StringUtilities *)stringUtilities ^ note: return type not imported - (StringUtilities *)stringUtilities ^ note: interface StringUtilities is incomplete - (StringUtilities *)stringUtilities ^ note: interface StringUtilites forward declared here @class StringUtilities I thought this scenario is fixed as part of proposal: # 0384-importing-forward-declared-objc-interfaces-and-protocols.md However it is not working for me. May be it is due to it being approved as part of Swift 5.9, whereas in my machine 5.8.1 is used or am I missing anything else over here? Update: I installed Xcode 15 and double checked the swift version which is 5.9, however I am still getting the error. Any idea why it is not working for a framework target?

I am developing a game in which my Locomotive is following a UIBezierPath that mimics an oval shaped Track. The math of the following is not "adding up" .. if it is, I am obviously not understanding the math of the layout. Bottom line = the following code does not display the UIBezierPath. Here's the code that creates this UIBezierPath .. please note the math in the comments: func createTrainPath() { trackRect = CGRect(x: 0.0, y: 0.0 - roomHeight/2 + tracksHeight, width: tracksWidth, height: tracksHeight) // trackRect = (0.0, -207.0, 940.0, 476.0) // portrait // trackRect = (0.0, -274.0, 470.0, 238.0) // landscape print("trackRect = \(trackRect!)") trackPath = UIBezierPath(ovalIn: trackRect) let theTrackShapeNode = SKShapeNode(path: trackPath.cgPath, centered: true) theTrackShapeNode.zPosition = 100 // for testing theTrackShapeNode.position = myTracks.position theTrackShapeNode.lineWidth = 4.0 theTrackShapeNode.strokeColor = SKColor.blue if let ourScene = GameScene(fileNamed: "GameScene") { print("here") // this shows ourScene.addChild(theTrackShapeNode) // does *not* show? } } // createTrainPath In Portrait mode, the UIScreen measures 1024 x 1366 and the Track measures 940 x 476 with its top edge down 207 from the center of the UIScreen. In Landscape mode, the UIScreen measures 1366 x 1024 and the Track measures 470 x 238 with its top edge down 274 from the center of the UIScreen. In both modes, the bottom edge of the Track is supposed to be flush with the bottom edge of the UIScreen .. and it is. If the math is correct, then I am obviously not understanding the math of the layout .. because the UIBezierPath is not showing. The math appears correct .. but the UIBezierPath just is not showing. So where is my brain off-center?

Hi, Everyone I set up a class for sharing photos to facebook. The codes of the class are as following. But when I call the function "shareToFacebook", there is no dialog to show. What's the issue in these codes? I am using iOS 17.0, Xcode The guide from Facebook hasn't updated. import SwiftUI import FBSDKShareKit import FacebookShare @Observable class ShareFacebook { var content = SharePhotoContent() var images : [UIImage] = [] var photos : [SharePhoto] = [] func shareToFacebook() { for image in images { let photo = SharePhoto( image: image, isUserGenerated: true ) photos.append(photo) } content.photos = photos let dialog = ShareDialog( viewController: UIApplication.shared.currentUIWindow()?.rootViewController, content: content, delegate: nil ) dialog.show() } } //button for sharing //Sharing to Facebook Button { for image in photos { let image = UIImage(data: image.imageData) sharedPhotos.append(image ?? userViewModel.render(image: Image("photoForNil"))! ) } shareToFacebook.images = sharedPhotos shareToFacebook.shareToFacebook() }label: { Image("share") .resizable() .frame(width:18, height: 18) .padding(.trailing,30) }

I am trying to use code from Apple's sample project on StoreKit (Implementing a store in your app using the StoreKit API). However, even if I don't make any changes to this sample project except enable "complete" concurrency checking in the build settings, I get warnings like Capture of 'self' with non-sendable type 'Store' in a '@Sendable' closure. How worried should I be about these warnings and how can I fix them?

CallKit is not get updated on iPhone 14 with Dynamic Island When I am receiving incoming call I need to update localizedCallerName in CallKit. As of iOS 17.2, localizedCallerName does not change. Is there anything I need to specify to update the name? Looks like the problem is related to CXCallUpdate() This is the code I use for updating caller name: func updateCallerName(_ call: Call) { let update = CXCallUpdate() update.localizedCallerName = call.localizedCallerName cxProvider.reportCall(with: call.uuid, updated: update) }

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!

Hi, I'm working in a MacOS Swift app that uses hdiutil and asr. Although I can send the sudo credentials and it can be read perfectly in the terminal, sometimes it appears that they are not enough to allow the program to run, throwing the following error: (asr) Failed to create source stream for replication Volume replication failed - Operation not permited This seems to be a permisions issue, because the very same code run perfectly when it is started from the terminal (szh). What would be the most practical way to overcome this issue? Any help will be highly appreciated.

A swift function name as getDataFromC which can connect with C function. A C function name as ExternalMethod which will receive the connect from swift. The parameter will be fill by call setData function. I can confirm that the entire structure return to getDataFromC was successful. Because I print the data of other structure members to check the correctness of the data. However, I don't know how to translate the largeData to [UInt8]. I try UnsafeMutableRawPointer type. I don't know what to do for the following action. I expected that output.largeData can be translate to [UInt8] type. //Bridging header file struct myStruct { void *largeData; int largeDataLength; int smallData[3]; } //C file void setData(myStruct* data) { int i = 0; uint8_t array[1024]; memset(array,0x66,1024); data->largeData = array; data->largeDataLength = 1024; data->smalData[0] = 0x99; data->smalData[0] = 0x88; data->smalData[0] = 0x77; } void ExternalMethod(myStruct* data) { setData(&output); } //Swift file func test() { var output = myStruct() getDataFromC(&output); var myPointer: UnsafeMutableRawPointer = output.largeData /* Here: I don't know how to translate data from myPointer to [UInt8] */ print("smallData: \(output.largeDataLength)") // 1024 transmission is correct print("smallData: \(output.smallData.0)") // 0x99 transmission is correct print("smallData: \(output.smallData.1)") // 0x88 transmission is correct print("smallData: \(output.smallData.2)") // 0x77 transmission is correct }

I have a swift callback function that accumulates data from the gyroscope handler CMGyroData to value, and takes care that it never goes below zero. Any thoughts why I got this crash? var value: Double = 90 func test(d: Double) { value -= d if value < 0 { value = 0 } else if value > 180 { value = 180 } // Double value cannot be converted to UInt8 because the result would be less than UInt8.min // according to Xcode, value is 0 let angle = UInt8(value.rounded()) print(angle) } During the crash, the debugger shows that value is 0, and the raw memory is 0x0000000000000000. I've heard about negative zero, but then the raw memory would be 0x8000000000000000. Either way, it makes no sense for the UInt8 constructor to fail. (lldb) p value (Double) 0 (lldb) p value.rounded() (Double) 0 (lldb) p UInt8(value.rounded()) (UInt8) 0 Xcode 15.1, iPhone 7 Plus, iOS 15.8 Edit: As a good measure, I changed that line to let angle = UInt8(Int(value.rounded()))

On macOS Sonoma I have a SwiftUI app that correctly plays remote video files and local video files from the app bundle. Where I'm having trouble is setting up the AVPlayer URL for a UVC camera device directly connected on the Mac. let url = URL(string: "https://some-remote-video.mp4")! player = AVPlayer(url: url) player.play() Is there some magic to using a UVC device with AVPlayer, or do I need to access the UVC device differently? Thanks, Grahm

Hi all, I'm trying to find the reason why my app is crashing and fix it. This is just happening in some devices and others are working fine.

I'm creating an app with a video player streaming video from an URL. The AVPlayer only takes the URL address of the video but I'd like to create a custom URLRequest and then use that to stream the video from online. So current situation is this: let videourl = URL(string: "videofoobar.com") let player = AVPlayer(url: videourl) player.play() And I would like to go to something like this: let videourl = URL(string: "videofoobar.com") var request = URLRequest(url: videourl) let player = AVPlayer(request: request) //This obviously fails, any workaround? player.play() I know it is not possible to do it like this as AVPlayer only takes URL or AVPlayerItem as parameter. Is there any workaround to make URLRequest and then give it to AVPlayer for online streaming?
