Using AVSpeechSynthesizer, I noticed that some works in UPPERCASe are not correctly spoken. SMALL is pronounced small but WIDTH is pronounced W-I-D-T-H I reproduced the problem in playground: let sentence = "Hello everyone. Two minutes to go. SMALL WIDTH." let synthesizer = AVSpeechSynthesizer() let utterance = AVSpeechUtterance(string: sentence) utterance.voice = AVSpeechSynthesisVoice( 	language: "en-GB" ) utterance.rate = AVSpeechUtteranceDefaultSpeechRate * 1.05 synthesizer.speak(utterance) Is it the expected behaviour ?

I suspect this point has been discussed in length, but I would like to find some reference to the design logic behind some Swift key aspect : the assignment operator, by value or reference. We know well how = works, depending it deals with reference or value (knowing the consequence of misuse) and the difference between the 2 : class AClass { var val: Int = 0 } struct AStruct { var val : Int = 0 } let aClass = AClass() let bClass = aClass bClass.val += 10 print("aClass.val", aClass.val, "bClass.val", bClass.val) let aStruct = AStruct() var bStruct = aStruct bStruct.val += 10 print("aStruct.val", aStruct.val, "bStruct.val", bStruct.val) Hence my question. Was it ever considered to have 2 operators, one used to assign reference and the other to assign value? Imagine we have : = operator when dealing with references := operator when dealing with content. Then let bClass = aClass would remain unchanged. But var bStruct = aStruct would not be valid anymore, with a compiler warning to replace by var bStruct := aStruct On the other end, we could now write let bClass := aClass to create a new instance and assign another instance content, equivalent to convenience initialiser class AClass { var val: Int = 0 init(with aVar: AClass) { self.val = aVar.val } init() { } } called as let cClass = AClass(with: aClass) But the 2 operators would have made it clear that when using = we copy the reference. When using := we copy content. I do think there is a strong rationale behind the present design choice (side effects I do not see ?), but I would appreciate to better understand which.

I have created a new entry in the capability list (background modes) None is selected, so that seems to have no effect. However, I would like to remove this entry to clean the screen. But I cannot find any "-" button, nor contextual menu, nor editing in XML… Is it simply possible to remove ?

I consider the following distribution scheme for some Mac App: distribute the commercial (paying) version on Appstore propose a free demo version (of course limited in some aspects) on a web site. This would of course be notarised. The reason is to avoid having several versions on the Appstore which could create some confusion. The 2 versions would have similar names and differ essentially in the size of data they can handle. Does anyone know if this is authorised by the Appstore Guidelines ? Or must I publish both on the AppStore ? Is there a risk my app being rejected as spam ?

In a MacOS App: When I create a file (in a folder), I save a security bookmark for the file. if I ask user to authorise its folder (before creating the file in it), I can save its bookmark too, allowing to create other files in this folder. So, when I create a file and need to create a companion (eg, a Results file), I first ask access to the folder, then create the file and create the results file in the same folder (hence having sandbox authorisation). My understanding is that it is not possible to programmatically create and save the folder bookmark, after deriving its url from the file url, without requesting user to explicitly grant access (with NSOpen panel) ? Which would be very logical as it would deny the goal of security bookmarks. So, is user explicit authorisation required (logical but creates more complexity when user moves files in the Finder). Note: In fact don't really need it, as I save bookmark for every accessed file, but I would like to know.

We have been waiting for this for many years. And the icon is there, at the right most That's a GREAT plus for the forum.

The Code Block doesn't number lines anymore. The work around is to ask for Numbered list in addition to Code block. Just applying Code Block: required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) commonInit() } Code Block AND Numbered List (or the other order) 1. required init?(coder aDecoder: NSCoder) { 2. super.init(coder: aDecoder) 3. commonInit() 4. } Is there another way to get numbering directly ?

In this app, I have: a VC as entry point (root) which segues (push) to a SplitViewController On iPad, when I get into the splitView, I can get back to the root by dragging down the split view. But on iPhone, this does not work: even though presentation is .automatic, Splitview covers all screen. No way to get back. I tried to create a back button in the detail views… Could not get it. What is the best way to do this ? is there a setup for the initial segue or the views presentation modes to allow pop back ? can I add a back button ? Where, calling what action to return ? I cannot embed splitViewController in nav stack … I would like to have the same solution on both iPhone and iPad…

In the new version of download > More, there doesn't seem to be a way to filter search efficiently. I searched for instance for MacOS (to see all releases). I get a very long list (200+) references, with a lot of Xcode, but nothing specific to MacOS. If I search for Xcode 11, I get all Xcode references: I added quotes to try and force an exact search, I just get a Java extension… That was not the case in the previous version of the more page. Or do I miss something ?

Even though I have selected all the notification options in my profile, I do not receive any mail (since about a week), at least when an answer is marked as correct. I did check they are not in spam. What do I miss ?

How to reorder a pdf document? move page p after page n, or at a given m position. add new page at certain position rotate a page 90° or 180°. I've seen libraries, but I would prefer to redevelop those simple functions directly in an iOS app (Swift). I don't need to edit the document content, just rearrange.

I try to rotate a page 180° in a pdf file. I nearly get it, but the page is also mirrored horizontally. Some images to illustrate: Initial page: Result after rotation (see code): it is rotated 180° BUT mirrored horizontally as well: The expected result It is just as if it was rotated 180°, around the x axis of the page. And I would need to rotate 180° around z axis (perpendicular to the page). It is probably the result of writeContext!.scaleBy(x: 1, y: -1) I have tried a lot of changes for transform, translate, scale parameters, including removing calls to some of them, to no avail. @IBAction func createNewPDF(_ sender: UIButton) { var originalPdfDocument: CGPDFDocument! let urls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask) let documentsDirectory = urls[0] // read some pdf from bundle for test if let path = Bundle.main.path(forResource: "Test", ofType: "pdf"), let pdf = CGPDFDocument(URL(fileURLWithPath: path) as CFURL) { originalPdfDocument = pdf } else { return } // create new pdf let modifiedPdfURL = documentsDirectory.appendingPathComponent("Modified.pdf") guard let page = originalPdfDocument.page(at: 1) else { return } // Starts at page 1 var mediaBox: CGRect = page.getBoxRect(CGPDFBox.mediaBox) // mediabox which will set the height and width of page let writeContext = CGContext(modifiedPdfURL as CFURL, mediaBox: &mediaBox, nil) // get the context var pageRect: CGRect = page.getBoxRect(CGPDFBox.mediaBox) // get the page rect writeContext!.beginPage(mediaBox: &pageRect) let m = page.getDrawingTransform(.mediaBox, rect: mediaBox, rotate: 0, preserveAspectRatio: true) // Because of rotate 0, no effect ; changed rotate to 180, then get an empty page writeContext!.translateBy(x: 0, y: pageRect.size.height) writeContext!.scaleBy(x: 1, y: -1) writeContext!.concatenate(m) writeContext!.clip(to: pageRect) writeContext!.drawPDFPage(page) // draw content in page writeContext!.endPage() // end the current page writeContext!.closePDF() } Note: This is a follow up of a previous thread, https://developer.apple.com/forums/thread/688436

I use UIActivityViewController to airDrop pdfFile (pdfURL) from iPhone to iMac. Works well, file is airDropped. let activityVC = UIActivityViewController(activityItems: [pdfURL], applicationActivities: nil) present(activityVC, animated: true, completion: nil) I want to customise it: limit services to AIrDrop and mail How can I exclude such services as WhatsApp, Notes… ? perform some action once the file has completed airDrop or once cancelled. I tried to implement with completionWithItemsHandler:         activityVC.completionWithItemsHandler = { (activity, success, items, error) in             print("Completed")         } This doesn't work, print is not executed. My ultimate goal is to close the activityVC automatically once action was completed, without need to tap close button. Should I define some content for applicationActivities ?

I try to exclude some activities from UIActivity. It works as expected when exclusion is done directly with the activity, as with: UIActivity.ActivityType.message, UIActivity.ActivityType.airDrop but not when activity is declared with an init as with: UIActivity.ActivityType(rawValue: "net.whatsapp.WhatsApp.ShareExtension"), UIActivity.ActivityType(rawValue: "com.ifttt.ifttt.share"), So, with the following code: let excludedActivityTypes = [ UIActivity.ActivityType.message, UIActivity.ActivityType.airDrop, UIActivity.ActivityType(rawValue: "net.whatsapp.WhatsApp.ShareExtension"), UIActivity.ActivityType(rawValue: "com.ifttt.ifttt.share") ]         let activityVC = UIActivityViewController(activityItems: [modifiedPdfURL], applicationActivities: nil)          activityVC.excludedActivityTypes = excludedActivityTypes message and airDrop do not show, but WhatsApp and IFTTT still show. I have tested with         activityVC.completionWithItemsHandler = { (activity, success, modifiedItems, error) in             print("activity: \(activity), success: \(success), items: \(modifiedItems), error: \(error)")         } that WhatsApp and IFTTT services are effectively the ones listed here. When selecting WhatsApp, print above gives: activity: Optional(__C.UIActivityType(_rawValue: net.whatsapp.WhatsApp.ShareExtension)), success: false, items: nil, error: nil

When testing in simulator with Xcode 13, I noted a subtle difference in the display of WKInterfaceLabel between Watch series 6 and series 7. WKInterfaceLabel is in a WKInterfaceGroup. On Series 7: the text Fast Driving is clipped with round corner at top and bottom On Series 6, round clipping is much less (noticeable on leading F and D) I could not find what parameter has changed in IB nor how to change this round corner value. Nor why such a change ?
