How do you access the iPhone Settings App? How do you set up your own options and how do you read the option setting status from swiftui. Is there some kind of list of standard options available?
I've checked several books I have and Apple documentation online without finding anything on the subject. Maybe at least point me to some documentation.
Managing settings is not UI related, so it really has nothing to do with SwiftUI.
That said, read up on UserDefaults and Settings Bundles.

I have a situation where I need to enable copy/paste only among a bunch of enterprise apps on a managed device.
This lead me to UIPasteboard, but looks like for such a feature we need all apps to be in the same app group.
Is there a possibility to restrict copy/paste (and other menu options) to only some applications (not in the same app group) ?
I am only aware of custom named UIPasteboards, couldn't find any other hint in documentations or wwdc videos.
Any help is appreciated.
I'm creating a messaging app and I would like to enable other apps to share text to my app via the share menu option.
How do I get my app listed in there?
This is the menu I would like to get listed in:
In iOS 8, Apple has now enabled a way for you to add your application to a user's Share Sheet as one of many features of Extensibility, which aims to make your app available to the user even when closed.
You can read a lot more about share extensions here, or go straight to Apple's pre-release documentation to dive into the code.
Update: Above link of Apple documentation is not working, check here App Extension Programming Guide: Share
You can do this by adding a few entries into your apps info.plist.
Here's a post that should answer this for you.

You can't automatically be added to the UIActivityViewController in other apps. The only things that appear on that "share menu" are a few predefined apps that Apple has added support for, as well as any other app specific activities an app decides to add.
You can setup your app to appear in a list of apps for opening a file but that is not the same as what you are asking for here.
I am assuming it is not possible to add apps to the native share dialog, like the one used in the Camera Roll. However I see screenshots around with different apps in the dialog.
Is it only apps that are integrated in the OS that can be in this dialog? Or is it possible with some scheme or something?
I have researched the possibilities of UIDocumentInteractionController mentioned by 'The Tiger' and came to the conclusion that it is not possible.
I have looked at the Apple Documentation, declaring the Document Types in the info.plist works for other apps but not for Mail, Images / Camera Roll / etc; the native share dialogs.
Edit:
I really don't get the downvotes....
Here are some references that say it is not possible:

You need to subclass UIActivity to achieve this.
Theres an example for Dropbox:

Register your app as supporting the file types that you want to open and add the code to open them. See Document Interaction Programming Topics.
This question could also be a general "How to change info.plist contents at compile-time" but I know it's a complex issue that is handled differently on iOS and MacOSX. The thing is that specifically when working with the Facebook SDK, it feels kind of wrong supplying my FB app-id twice - once in the "URL types" dictionary under "URL schemes" in the app's info.plist and once in my code. I want to be able to change the app-id dynamically from within my code without touching the info.plist file. I looked into Apple's launch services and found a potentially helpful "LSSetDefaultHandlerForURLScheme" method, only to find out that I was looking at the MAC developer library. I saw some other SO questions about this issue but the general opinion seems to be that this is not doable. Any ideas that don't involve pulling information out of the plist at compile time? (I want to be able to support several app-ids that are defined in a specific header file in my code).
Thanks!
Is it possible to share on-disk data between iOS applications, or are they truly sandboxed? In other words if I wanted to make a shared repository of data to be accessed (and/or modified) by one or more of my apps, could it be done?
One of the listings on the iOS features page is "Share Data Among Apps", but is this what I'm looking for, and what are the related APIs?
Googling hasn't turned up much else in this area and I know I can construct a path to just about anywhere in the iDevice directory structure. Would it be against Apple's TOA, leading my apps directly to rejection, or is there hope for such an architecture?
Nothing too easy unless your app is iPad only. Otherwise this thing speaks about URL Prefixing. See "Implementing Custom URL Schemes" http://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/StandardBehaviors/StandardBehaviors.html%23//apple_ref/doc/uid/TP40007072-CH4-SW7.
Here is some info on the iPad only Doc support: http://developer.apple.com/library/ios/#documentation/General/Conceptual/iPadProgrammingGuide/CoreApplication/CoreApplication.html%23//apple_ref/doc/uid/TP40009370-CH6-SW2 see "Document Support on iPad Devices". This DOES NOT work on iPhone/iPod
That looks like marketing speak. The only way to share data locally is to pass it in the URL when launching another app. Otherwise, you need an internet server based solution.
Another thought: can you use TCP locally between apps with the new multitasking support? Apps like Air Sharing are allowed to create listening sockets.
using ios keyChain you can share data between apps.
