Prior to 18.x, this has worked for years. However, if a port is included, the behavior in 18.x is to return "///some/path". In all previous versions it correctly returns "/some/path". Is this a bug, or documented change we missed? func relativeURLString(for urlString: String) -> String? { guard var components = URLComponents(string: urlString) else { return nil } components.host = nil components.scheme = nil // WE FOUND IF YOU NIL THE PORT BEFORE HOST AND SCHEME, IT WORKS components.port = nil return components.string }

I've got some materials in an app's bundle (some info.plist values, and some images in .xcassets files etc.) If I access them from within an app extension (a notification service extension, notification content extension for example), then it appears to work. However while running the extensions in the debugger, there were some messages in the console saying the app bundle wasn't loaded. So despite it working, this message made me wonder if its not a safe practice and it working was luck and/or timing etc. and if the materials should instead be duplicated within the extension bundle and obtained from there instead of accessing them from the app bundle?

I have a class object created dynamically using Runtime, and I want to release some manually allocated memory resources when this object is deallocated. To achieve this, I added a custom implementation of the dealloc method using the following code: SEL aSel = NSSelectorFromString(@"dealloc"); class_addMethod(kvoClass, aSel, (IMP)custom_dealloc, method_getTypeEncoding(class_getInstanceMethod(kvoClass, aSel))); However, I encountered some issues. If I don't call the superclass's dealloc method in the cus_dealloc function, the superclass's dealloc implementation will not be executed. On the other hand, if I explicitly call the superclass's dealloc method, the program crashes. Here is the implementation of the cus_dealloc function: void custom_dealloc(id self, SEL _cmd) { // Release other memory ![]("https://developer.apple.com/forums/content/attachment/c7b0c16b-be23-4776-b8db-f22b661c5e7d" "title=iShot_2025-01-03_19.31.34.png;width=1080;height=1895") Class superClass = class_getSuperclass(object_getClass(self)); void (*originIMP)(struct objc_super *, SEL, ...) = (void *)objc_msgSendSuper; struct objc_super *objcSuper = &(struct objc_super){self, superClass}; originIMP(objcSuper, _cmd); } demo

Context: SwiftUI TextField with a String for simple math using NSExpression. I first prepare the input string to an extent but a malformed input using valid characters still fails, as expected. Let's say preparedExpression is "5--" let expr = NSExpression(format: preparedExpression) gives FAULT: NSInvalidArgumentException: Unable to parse the format string "5-- == 1"; (user info absent) How can I use NSExpression such that either the preparedExpression is pre-tested before asking for actual execution or the error is handled in a polite way that I can use to alert the user to try again. Is there a Swift alternative to NSExpression that I've missed?

We have a sample code that initialises an NSAttributed string with simple HTML code and the result differs massively since XCode 16 and iPadOS 18 SDK. DESCRIPTION OF PROBLEM Since Xcode Version 16.1 HTML content passed into an NSAttributedString is not rendered correctly. Specifically, enumeration characters (such as bullet points or numbers) and the proper indentation for text within list items are missing. As a result, the structure of the HTML content, especially ordered and unordered lists, is not displayed as expected. STEPS TO REPRODUCE A UILabel was added to the view in a new Objective-C project in Xcode. A HTML string containing and Tags was converted into an NSAttributedString (With NSAttributedString::initWithData and NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType Parameter)within the viewDidLoad method and assigned to the UILabel. Expected Result: The lists should be displayed correctly with enumeration characters and appropriate indentation, as shown in the attached screenshot expected_result.jpeg. Same Code still works as expected using XCode 15.x Actual Result: The list is displayed without enumeration characters or indentation, which matches the attached screenshot actual_result.jpeg. Sample Code NSString *html = @"Es ist wichtig, dass Sie Ihren Arzt informieren:\n<ol>\n\t<li><strong>HIER !!!!!!! </strong>Wenn Sie gegenw&auml;rtig mit Zometa&reg;, dass die gleiche aktive Substanz enth&auml;lt wie Aclasta&reg; behandelt werden.</li>\n</ol>\n\n<ul>\n\t<li><strong>Hier !!!!!!</strong> Wenn Sie Nierenbeschwerden haben oder hatten, denn Ihre Nieren m&uuml;ssen korrekt funktionieren, um das &uuml;berfl&uuml;ssige Aclasta &reg; das f&uuml;r Ihre Knochen nicht ben&ouml;tigt wird, ausscheiden zu k&ouml;nnen.</li>\n\t<li>Wenn sie Medikamente einnehmen, die Kortsion als Bestandteil enthalten (z.

Hello, we are processing the first network permission request transaction on iOS. We have found that when the CTCellularData is in the kCTCellularDataNotRestricted state and we attempt to perform a network access in the callback function, an exception is reported. How can we resolve this issue? I’ve seen that some solutions on the internet suggest adding a delay of 1 second. Are there any other methods?

iOS 18 broke some functionality in my Objective-C app with regard to using the DatePicker. The key lines are as follows: datePicker.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:timezoneOffset]; datePicker.date = [NSDate date]; When timezoneOffset is -29380, the value for San Francisco, the Date Picker is a whole MONTH off. It shows November instead of December. But when it is -29359, the value for Seattle, which is in the same time zone (PST), it shows the correct month. In fact, even towns surrounding San Francisco usually return the correct value. Some other cities in other time zones also cause the Date Picker to be a month off.

is forKey:fileSize considered accessing non-public API? has your app been rejected at review stage due to this? let resources = PHAssetResource.assetResources(for: asset) if let resource = resources.first { if let fileSize = resource.value(forKey: "fileSize") as? Int { return fileSize } }

Here is a relatively simple code fragment: let attributedQuote: [NSAttributedString.Key: Any] = [ .font: FieldFont!, .foregroundColor: NSColor.red] let strQuote = NSAttributedString.init(string:"Hello World", attributes:attributedQuote) strQuote.draw(in: Rect1) It compiles without an issue, bur when I execute it, I get: "*** -colorSpaceName not valid for the NSColor <NSColor: 0x6000005adfd0>; need to first convert colorspace." I have tried everything I can think of. What's going on?

my Date type data is "2024-12-28 15:00:00 +0000" and when I use Date formatter to format date with timezone TimeZone(identifier: "Asia/Seoul"), date formatter return wrong year like below (lldb) po print(date); let formatter = DateFormatter(); formatter.timeZone = TimeZone(identifier: "Asia/Seoul"); formatter.dateFormat = "YYYY-MM-dd"; formatter.string(from: date) 2024-12-28 15:00:00 +0000 "2025-12-29" (lldb) po print(date); let formatter = DateFormatter(); formatter.timeZone = .gmt; formatter.dateFormat = "YYYY-MM-dd"; formatter.string(from: date) 2024-12-28 15:00:00 +0000 "2024-12-28"

Hello dear community, I have the sample code from Apple “CapturingDepthUsingLiDAR” to access the LiDAR on my iPhone 12 Pro. My goal is to use the “photo output” function to generate a point cloud from a single image and then save it as a ply file. So far I have tested different approaches to create a .ply file from the depthmap, the intrinsic camera data and the rgba values. Unfortunately, I have had no success so far and the result has always been an incorrect point cloud. My question now is whether there are already approaches to this and whether anyone has any experience with it. Thank you very much in advance!!!

I am writing a SwiftUI-based app and have the following requirements: Use a file browser (such as UIDocumentPickerViewController) to find an arbitrary file (not one that the application knows how to open) which is external to the app bundle but local to the device the app is running on - either in local storage or on an iCloud drive. Save this location. At a later time, open this file. The file should open in an app that knows how to open it or in a browser. Do all of the above in a way that works with multiple devices (synced via CloudKit/SwiftData). For example, select a file on my iCloud drive on my Mac, then save it (using CloudKit/SwiftData) and open it on an iPad that has an app that can open it. I am addressing requirement #1 using UIDocumentPickerViewController wrapped with a UIViewControllerRepresentable. It returns a security-scoped URL. (Note: this worries me because of requirement #4). I use the Bookmark API to implement requirement #2. For requirement #3, I load the bookmark data, convert it back to a security-scoped URL and either Link("Open", destination: url) or @Environment(\.openURL) private var openURL if url.startAccessingSecurityScopedResource() { defer { url.stopAccessingSecurityScopedResource() } openURL(url) { accepted in // do something here } } Both of these implementations fail. The Link call responds with "invalid input parameters" (Error Domain=NSOSStatusErrorDomain, Code=-50), the openURL() call just returns false. So, my questions are: Since it appears the Link and openURL work for internet URLs, but not for security-scoped file URLs, how to I cause a document to be opened (using an application which knows how to open it or a browser). Since UIDocumentPickerViewController is returning a security-scoped URL, how can I make this work on a different device than the one on which the user selected the document? (Assuming, of course, that we are talking about a document that is on an iCloud drive that both devices have access to).

Hi everyone, I am wondering under which settings the camera(s) were set by the time they were calibrated. For instance, one aspect that is easy to find is the reference resolution of the images taken when calibrating the intrinsics, this is by retrieving intrinsicMatrixReferenceDimensions. Making sure that the principal point is referenced to the by the time resolution used when the calibration was ongoing. However, recently I saw that there are focusing modes that potentially displace the lens' physical position. Settings like: AutoFocusRangeRestriction: none, near, far setFocusModeLocked: Locks the lens position at the specified value, and sets the focus mode to a locked state. My concern lies the impact this focusing lens displacements can have on the intrinsic matrix parameters, like these parameters no longer describe the camera since the lens position has changed. In simple words, what is the focus 'mode'/'range' the cameras were set when calibrating them for intrnisics?

I have been trying to accept drops from Apple Mail which do supply data with type identifiers : com.apple.mail.email The problem is that even though the drop says it does contain items for com.apple.mail.email it does provide the items for com.apple.mail.email. Mail dropped from Microsoft Outlook however confirms to the protocols and returns the items for com.apple.mail.email Is this a known issue with Apple Mail and is there are reason for what seems to be a non-compliance to it own standards in Apple Mail?
