In this documentation for completeRequest(returningItems:completionHandler:), there is a box shaded yellow that says: Important If the system calls your block with an expired value of true, you must immediately suspend your app extension. If you fail to do this, the system terminates your extension’s process. How does my app or my Share Extension know when the system calls the block spoken of?

Where is Apple's documentation of NSConcreteAttributedString? I need to get the String from NSExtensionItem.attributedContentText property, which is of type NSConcreteAttributedString.

The sample project CloudKitShare downloaded from developer.apple.com Sharing CloudKit Data with Other iCloud Users has a line of code in HandleCloudKitError.swift that optionally casts an instance of Error to a variable of type NSError. guard let nsError = error as NSError? else { return nil } Under what conditions would this fail? I thought this would always succeed. How do I find out why the cast is unsuccessful? When I put code that prints the type of variable 'error', it seems to always result in Optional like so: Code: guard let nsError = error as NSError? else { print(type(of: error)) return nil } Optional

What is the purpose of the following line of code? It doesn't seem to do anything. If it were in Playground or in a print statement it would at least show something. _ = masterVC.view It's in Apple's sample code at Sharing CloudKit Data with Other iCloud Users. Here's the complete significant code that contains that line of code: if let masterVC = masterNC?.viewControllers.first as? ZoneViewController {       _ = masterVC.view       start ? masterVC.spinner.startAnimating() : masterVC.spinner.stopAnimating() }

How do I get my iOS app to run code when something specific in a message in Messages happens, like a specific phone number sends a specific phrase?

I'm curious why I don't see posts about Xcode crashing. Since I updated both macOS Monterey 12.6 and Xcode 14, Xcode repeatedly crashes, becoming more frequently, even within 20 seconds between the last two crashes. Am I the only one getting these crashes?

What framework would I use to make one of those popup menus that I see when I long press a field when I look at a Contact in Contacts. The popup menu is black. It looks like a horizontal bar with items separated by a very think vertical white line between each item. When I press a field while viewing a Contact, the menu gives an option to Copy and another option for iPhone to Speak.

I have an app that uses CKShare and UICloudSharingController to share data with other users of my app. I noticed that when Owner shares with UserA, UserA is able to "copy" the link or "send" the link, as the title of the button use. How do I disable that completely so that only the owner can copy or send the link? Also, what determines whether it says "Copy Link" or "Send Link"? Does that have to do with the version of iOS? I've tried every combination of UICloudSharingController.PermissionOptions to set to UICloudSharingController..availablePermissions ... [.allowPrivate, .allowReadOnly], [.allowReadOnly], [.allowPrivate], and []. Setting the value to [] sets it to .standard, which does the exact same thing as [.allowPrivate, .allowReadOnly], though the value is different for availablePermissions property.

I don't see any current posts about the warning that says "PosterBoard quit unexpectedly." on my Mac. Older posts say this is an error generated by Xcode Simulator. I tried one of those solutions but I still see this warning coming up. I am also not using Simulator. I'm using an actual device - an iPhone 13 Pro Max running iOS 16.6. When I click on Reopen in that alert box telling me that warning message, I get a warning in an alert box with a picture of the Finder icon on it, and it says "You can’t open the application “PosterBoard.app” because this application is not supported on this Mac.". Anyone else have this problem and know what do do about it? Like fix it or get around it?

I'm able to get text to speech to audio file using the following code for iOS 12 iPhone 8 to create a car file: audioFile = try AVAudioFile( forWriting: saveToURL, settings: pcmBuffer.format.settings, commonFormat: .pcmFormatInt16, interleaved: false) where pcmBuffer.format.settings is: [AVAudioFileTypeKey: kAudioFileMP3Type, AVSampleRateKey: 48000, AVEncoderBitRateKey: 128000, AVNumberOfChannelsKey: 2, AVFormatIDKey: kAudioFormatLinearPCM] However, this code does not work when I run the app in iOS 18 on iPhone 13 Pro Max. The audio file is created, but it doesn't sound right. It has a lot of static and it seems the speech is very low pitch. Can anyone give me a hint or an answer?

What are guidelines for numbering the build number? Should it just start with 0 and increment by one each time I archive a project for distribution?

I included the Tests and UITests schemas when I created my Xcode project, but now I want to remove them. Even if I delete those groups, I still get build errors on the files and the files still show in the editor. How do I remove those files from my project for good?

Anyone know where I can get a list of all the UserDefaults keys? I can't find it in documentation.

I haven't been getting replies to my post. I didn't have this problem with the old system.
