I want to design an app that adds additional functionality/interfaces with the Music app. Is this possible?
This is not possible except for jailbroken devices.
You can, however, control the Music app by using the [MPMusicPlayerController +iPodMusicPlayer] object.
Basically each application that you download to an iphone exists in its own sandbox e.g. has its own file system, so it is not possible to interact with other applications. I guess it is a security thing
About the only way is passing a URL between the applications. It is not a shared memory space but a way to launch another app with stae in the URL. http://developer.apple.com/library/ios/ipad/#featuredarticles/iPhoneURLScheme_Reference/Introduction/Introduction.html

Is there any way to work with data in shared web credentials directly, like with keychain, without showing popups on SecAddSharedWebCredential and SecRequestSharedWebCredential?
Or are there any other methods to work with it?
I want to share some data (string) between apps with different development teams.
I will recommend you to use the KeychainAccess which is a simple swift wrapper. And using Keychain is the best way to store small pieces of data that are critical to your app, like secrets and passwords.
Also the tutorial from raywenderlich would help you use the Keychain Services API.
App groups can be an option for your use case. Read below the apple API documentation and medium post
App Groups
Use a shared app group to share data/files between two/more apps or containing apps. An app group creates a secure container that multiple processes can access. Normally, each process runs in its own sandbox environment, but an app group lets both processes share a common directory.

Since adding WiFi Network Programmatically in iOS is nearly impossible without jailbreaking the Iphone :(
Is it possible to Forget / Remove an already stored WiFi Network Programmatically with SWIFT or Objective-C without jailbreaking the iphone?
Unfortunately not, as this is not something done in the scope of an application.
And if it was possible, it seems like a sure way to not get your app approve for the App Store.
I need to be able to update my app from within the app itself. I know Sparkle works for Mac Apps but I can't seem to find any for iOS.
Edit: I am not asking how to bypass the review process. I was thinking that there might be frameworks similar to Clutch.io that allow updates to images/documents/etc from within the app. Or things like UrbanAirship that manage in app purchase data that allows an app to be extended from the app itself.
You can't replace your app with an updated one (except through the App Store) and you can't replace parts of your app with updated parts (that would make your app's code signature invalid); you can only update stuff that's outside of your app's bundle.
You can't update the app binary yourself, the system is responsible for updating all apps.
Though, if you just want to update some data in your app you can do that for sure.
Here is what I was looking for:
http://code.google.com/p/cooliris-toolkit/
It has a class called RemoteUpdater which allows me to download zip files of images/data or whatever I like to extend my content.
Depends on your needs. If you dont want to see the app you can also do an Enterprise Deploy.
Used by corporations to distribute apps to their clients or employees.
Needs a separate Apple account which costs more.
Uses same process as deploy to appstore
Archive > Distribute > create ipa/plist > copy these to webserver with html page with link to plist and user clicks on link from Safari on iOS Device and it installs.
Going back to CArpp Store review process after that is painful.
I want to make my iPhone app display on a Mac's screen, kind of like AirPlay does with other machines. The only way I have heard to do this is, although I do not like it, turn the iPhone into a server. Unfortunately, I cannot figure out how to do so. I also wanted to set it up in such a way that my Mac automatically detects it. I have seen a similar setup in the game Chopper 2. My Mac app will have a simple timer that fires every few seconds to look for the iPhone, in the same way that Chopper 2's "Find iPhone" button does.
Is there a simple way to turn the iPhone into a server, or start a "session" like Game Center does?
One last thing: I know it is somehow possible, because another app I have actually gives my iPhone a web address at the click of a button. It is called the Dicenomicon, if you want proof.
First there is no easy way to redirect your display to Mac, even if you made it a server of some kind.
Second, to discover or publish customized services on WLAN, you may want to refer to the samples on Bonjour:
CocoaHTTPServer: a simple TCP/HTTP server.
WiTap: an app that discovers and connects to services of the same kind on WLAN by Bonjour.
I'm not really sure what you mean by "server", because there is no way to share the screen of an iPhone using the official SDK, although this is possible by jailbreaking.
It would be possible, however, to send data back and forth between the Mac and iPhone, and display the data on the iPhone, on a Mac. Using that data, you could try to recreate the interface on the Mac. All of this could be accomplished using sockets. A class that might help with that would be cocoaAsyncSocket, which makes network programming a lot easier.
The auto-discovery of iPhones on the local network is achievable with Bonjour. Without getting into too many details, NSNetService would allow you to publish a service for your app from an iPhone, and NSNetServiceBrowser would allow you to find that service on the local network from the Mac. From the NSNetServiceBrowser, you could establish a socket connection with the iPhone.
Good luck!
You might want to take a look at the GameKit APIs, I know they do something similar between two iOS devices.

Not sure if this is possible, but I wanted to check it out.
I want to access the GPS features in iOS, specifically on iPad through my app. Ultimately the goal is to be able to see who else nearby is currently running the app as well. Is this at all possible or practical to implement?
Entirely. Check out the documentation on Core Location. Typically the way an app like yours works is that any devices running the app submit their location to a script on your server, then query that script for any other devices nearby.
