I'm looking at this Swift documentation on Literal Expression, particularly the #dsohandle literal. It's the last line in the table. I can't find any documentation by Apple for "dynamic shared object (DSO) handle", as it says in the very right-most column. When I do a search for "dynamic shared object", I find information for technology by other companies. Anyone have anything you can tell me about this?

What is that feature called that shows a picture of the entire contents of the file on the right-hand side of the editor and shows it very small like it's zoomed out and shows the part of the file that is currently showing in the editor in a different shade in the picture? I am describing this to the best of my ability. I hope it comes across clearly.

Am I able to see what Logger logs from my app when it's running on a device belonging to an external tester if my app doesn't crash? Am I able to see the logs if my app does crash? I am using Swift with Xcode for iOS.

Is there a way to use CallKit on the current service the device is subscribing to, such as ATT? I want to create an app that will block all emergency bypass, since I can’t programmatically turn emergency bypass off.

Apple Documentation says that there is only one CNContainer in an iOS device of type local. Creating a container of type exchange requires using Exchange, and creating a container of type cardDAV requires a server also. Is there any way to create a container of type unassigned? I would need to do this programmatically in Swift to use in my iOS app. This question and the posts it mentions give no answer.

Hi. Is there a way to programmatically allow my iOS app to prevent all calls from making a sound or causing the iPhone to vibrate, other than unselecting Emergency Bypass from each contact? If not, is there any way to temporarily or permanently unselect Emergency Bypass on any given Contact? If not, is there any way of programmatically shutting off the iPhone?

For iOS, is there any way to add words into the dictionary that voice dictation recognizes and to the dictionary that the bar on top of the keyboard uses, that shows suggestions for words? I would like to make an iOS app that uses Biblical words such as "thee" and "thou". Any ideas will be appreciated.

I have an iOS app already on the App Store. I just changed my business to an LLC. I would like to change the bundle identifier in the next version of the app to reflect my new website address. What would happen if I did this? I want to decide whether it would be worth the trouble.

I need to be able to identify a CNContact so as to associate it with a CKRecord in a iCloud private database. If I use a non-unified contact, would the identifier be unique across all existing iOS devices so that I could store the identifier property in a record in the user's iCloud private database to identify a specific contact? The documentation says that the identifier of a CNContact stored object is unique within the device. If I use a UUID value and store it in the iCloud private database to identify the specific contact, how would I match that with the contact? I would need to save that UUID value as part of the contact object as stored in the contact store. Is that possible without saving the UUID value in the notes property of the contact. It would be better if I could store the UUID value somewhere where the user could not access it and delete or edit it. Is there a way to make the notes property of a contact inaccessible to the user where even if he/she could see it, he would not be able to change it? I'm not very familiar with the hash and hashValue properties of NSObject object. Though unlikely, would one of those properties be able to identify a contact uniquely across all existing iOS devices so that I could store it in the user's iCloud private database in order to associate a certain record in that database with a specific contact?

Is it possible to observe the iOS Contacts app or the contacts store of a device using key-value observing? How would I find out? I can't find information on it when I do a search on Google.

Is there a way to put code in iOS that is always watching in the background for the contact store to change? If I put it in my app, then the user can close the app, and the app won't receive notifications when the contact store changes? Is there an app extension I can use that would allow me to do this, whether that is the intent of the extension or not?

I'm having trouble finding explanations for the different cases of Data.Deallocator enumeration. It's used with the [init(bytesNoCopy:count:deallocator:) initializer to Data class] (https://developer.apple.com/documentation/foundation/data/1780455-init) Here's the different cases: Data.Deallocator. The cases are: custom free none unmap virtualMemory Anyone know a website that explains those cases briefly and simply? Or do you know what they mean off the top of your head?

I'm starting to look into MDM and device management for my iOS app. I'm also wondering if there is any way to allow someone on a macOS or another iOS device take control of another person's iOS device to show them how to use their device and perhaps even take control of their device while the person using the controlled device watches what the the person in control of the device is doing so he can follow along. Is there something like this that Apple already has? Is it possible to do this? If it is possible to do this, can it be done in a commonly distributed device that anyone can install from App Store and not require any additional maintenance or extra setup? I think the word I'm thinking of is "supervised". I saw that word in another post. Is it possible for one device to give control over to another user on a different device without the first device being "supervised".

When I go to devices and simulators with my iPhone 8 plugged into my Mac, and then open device logs, I don't seen any recent logs. The last one was from november last year. Why are there no more recent logs? I went to my iOS device and searched for "log" in Settings, but there doesn't seem to be any setting to turn on logging. I also can't find any settings when I search for "developer" in settings. I thought I saw something in iOS that enabled me to send reports to Apple automatically on my iOS device. I don't know if that's what I really want.

At what point in the iOS development process using Xcode is my app name reserved on App Store? Last I remember when I published my iOS app for sale status on iOS App Store at App Store Connect I had to change my published app name because there were already other apps using that name. I think that was the name that was actually showing on the App Store, and not the name I put in the Product Name field when I first create the project in Xcode. I just tried to validate my iOS app and it wouldn't validate because it said there was already an app with that "App Name". I take it that means the name I put in the Product Name field when I first created the project, if I don't change it later. Is that correct? So if my iOS app project validates, does that mean I have that App Name reserved so that no one else can use it? How do I reserve a name for my iOS app so that no one else will get it once I reserve it?
