I am working on a project where I need to display network bandwidth value on a screen, which will keep on changing with the Network speed on my device. I don't want to implement a solution where I have to download a file every time and then check the speed. Please provide some alternate solution to it. Thanks
I have tried below mentioned solutions, but doesn’t suits my requirement.

I would like to make an app which can slow down a user's internet speed. Is there any ways? It's for a gym sports events where whenever the runner is running on the threadmill and with their speed on the threadmill,the download speed of a file is changed. For example if the running speed is faster,download speed is faster. Is there any codes that are able to control the internet speed? I looked up on stacksoverflow but all is on simulator.
There are no public APIs for doing this. I would suggest that you instead fake the reporting of progress.
If it is your app which is doing the downloading then if you implement the HTTP/FTP/whatever communication yourself over TCP/UDP your app can insert delays; or it can just download at network speed to a temporary location and transfer it from there to the correct destination at whatever speed it chooses.
If you are trying to slow down standard apps like Safari you could add a HTTP/FTP proxy to your system, which rather than simply proxying slowed down transfers. If you don't want to write a proxy from scratch take a look at Squid or GlimmerBlocker (I think its source is available, its in Java, this proxy is a Mac ad blocker demonstrating a proxy can be used for more than just proxying).
HTH, Have fun!

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 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.

I have a 3.5mm to IR sensor to connect to my headphone jack. I want to know if there's a way to create a basic app for my TV that will control it's Volume, Power On/Off, input, and number pad. I've kept researching for about a week now on how to do this, but haven't found an answer. Can someone help me?
Yes is it possible, you only need an application what play wav files.
Or jsut a file browser.
But you can find a plenty of applications and tutorials and details all over the internet.
