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:

I am trying to learn how to program an NFC, but the only tutorials that I could find used an app to do it. I also need to be able to use it on iOS devices (i.e. iPhone). This is my first time programming hardware. Is it possible to program an NFC without using an app to help? If so, how?

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 know this is probably a long shot but I wanted to know if there is any relatively easy way to run swift code which is stored on a server or hosted somewhere other than the application bundle. I would like to be able to change single lines of code without having to publish an update to the app.
If anyone could help or has a work around then that would be great.
Thanks
No it's both not possible (there is no compiler on an iOS device) and not allowed (downloading code is expressly forbidden by Apple's app store guidelines.)
So you both cannot and may not do this.

I was recently asked to create an iOS app for a client which controls all other installed apps' access to cellular data. For instance, the user would be able to turn off cellular data access to all apps but Safari.
I assumed that this wouldn't be possible because of sand-boxing but couldn't find any relevant info via Google or the developer's docs, so thought I'd ask the question here - is there a specific class or framework I should investigate?
No you can't , Apple does not allow such approaches . So there is no helping class or framework at all.

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.
