I want to creat an app that talks with other devices.
The app is for IOS 5 and up using Objective-C
I want to be able to send data between 2 IOS devices directly (not with a server or somthing).
How can I acomplish this?
Some say Bluetooth but it is very general..
Some say GameKit but I could not find any tutorial for GameKit since IOS 3 (and even then I found only 1 guide).
Can you help me understand which technology to use and maybe direct me to tutorials that explain all of it?
The data I want to send is short string \ 2 digits int's every couple of minutes.
Thanks,
Gal
This might be something for you:

As you mentioned. Using bluetooth with GameKit framework is the way to go.
You can use Peer-To-Peer setup and that means no server is required.

I want to make Wi-Fi file sharing in my app, that UIViewController will have http address which user will can to write in desktop browser and user will can pass data to application over Wi-Fi. How can I make it? What are any libraries for it? I use Swift 2.0 and Xcode 7. Like this
This is a broad question, here as a broad answer.
You could try using the Multipeer Connectivity Framework that was introduced in iOS7.
This essentially wraps zero-configuration networking so you don't need to worry about IP addresses.

I am trying to develop an app for iPhone (written in Swift, using CoreBluetooth) which needs to connect to a BLE module (that has to act as a peripheral), and send to this module some data. Unfortunately I cannot do this on my own because of my little knowledge. Can someone indicate me where to find this information? Or, as an alternative, does anybody know how can I do this?
I suggest you, Irrespective of language you are going to use, first understand the Core bluetooth framework . Go through each term . Then you can start with basic functionality like searching the peripherals , connect to the peripherals. Here are some links which can help you:
https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/CoreBluetooth_Framework/

With the new app-extension kit, I'd like to know if it's possible to build an app that tracks various usage statistics of other apps. For e.g., the no of times someone uses their calculator or the no of minutes spent on Quora.
This is a really nice idea to enhance the ability of iOS system. However, even in iOS8 this is unlike to achieve. Apple has offered so limited APIs for APPs to access other APPs. In those APIs, I cannot find any one to record other APPs' launching or closing. (Except you call that from your own APP so that you can record the time, but this is meaningless.)
In the official document for App Extension Programming, manager for APP is not a type that is mentioned in the guide. I'm afraid that you have read it and it cannot give you more help.
I tried to do research on the most detail list of iOS APIs to find whether this is possible. But since iOS5.0, Apple no longer provided the API diffs. Here is the search result.

I know I can't record a video while I'm on my phone in general and that if the capability existed or could exist that it would be a feature/option.
Are there apps that do this and if it can be done can someone help me get started code wise?
EDIT
Because there seems to be some confusion as to what I'm asking, I will clarify:
Are we able to launch phone calls using the iPhone regular calling feature and use the iPhone regular movie creating feature (the video camera) at the same time in an APP - as we know it can't be done generally.
Yes and no. You can't use Apple's built-in camera and phone to do it. But, obviously there are many apps (i.e. Skype and others) that use both camera and voice features in their VoIP implementations. So, it would take a custom camera and VoIP to accomplish this.

Adobe Photoshop has a feature called "Remote Connection" which allow device to mirror preview of current design to the screen.
I want to build the app like that, but I don't know which technology that help to start research to archive this goal.
Hope anyone could give me an idea to getting start.
Thanks!
Edit (For anyone have the same question):
I found the answer: Should use Bongjour service and Adobe Also have the SDK and sample code. The Photoshop Touch SDK can be found here http://www.adobe.com/devnet/photoshop/sdk.html
Remote connection is for apps to send and receive javascript packets through Photoshop's API. Check out their API guide. By the way its terribly buggy, outdated, and undocumented.
