I'm trying to build a swift app that would allow a user on one side to draw an image that will be updated in nearly real time on the other user's device, somewhat as if they were drawing on a whiteboard in person.
Anyone have any tips or places where I should start? I'm relatively new to swift. Thanks for your help.
This requires a persistent line of communication between your mobile device(s) and your server. Websockets allow this type of communication. I haven't implemented them myself so I can't provide implementation details, but there are plenty of resources available online.

I think Realm is exactly what you are looking for.

I am thinking the build my own home system that can do basic tuning channels or view lineup for my Comcast cable TV, like xfinity TV App does.
I am wondering if someone know Comcast open their API? or is there a way that can do it?
Thanks
Lewis
Most likely, you'll have to program against a 3rd party system that uses a CableCard.
To my knowledge the only way you can do something like this is to write a plug-in for Media Center on Windows with a CableCARD. Take a look at the Windows Media Center SDK Overview and see if it has the functionality you're looking for.
Nope, everything I've seen suggests that it's a private API. Which makes sense, they probably want you to have to use their services instead of creating your own.

I'm currently doing an internship in a medical laboratory
They want to buy Ipad and medical device connected to it
example: diabet tester http://www.ibgstar.us/
blood pressure monitoring system http://www.ihealth99.com/
I'm wondering if I can code my own application that gets the data from the medical device and then handle it?
thks for your answers
I think they're some step to success it .
At first you need a Hardware solution like said "Mundi".
You need to grab data from device and store them somewhere accessible (like in a BDD with online acces).
And then the iPad application just have to connecte to the data-Source and play with it
The short answer is YES.
There are many ways to get the data into the app via a network. If you would like to read from the device directly, you would have to additionally find a hardware solution.
I'm not sure this applies, but I've seen some really cool medical apps written using Harvard's SMART project. They provide a simple but effective framework, which is independent of the Hospital Information System (like Cerner, Epic, VistA).

I want to make an app like Instagram but the problem is where to store all text and images data, I have used Instagram when there is no connectivity available then app will show the last feeds even when app is freshly openend (not from background). It uses core data or sqlite.
I came across a scaling presentation from instagram a little while back where they talk how they started, using what and then how they approached the challenges.
See the link: http://www.scribd.com/doc/89025069/Mike-Krieger-Instagram-at-the-Airbnb-tech-talk-on-Scaling-Instagram
Hope this helps.
It's not known what Instagram uses. Use whatever you feel most comfortable with. Anything is possible with any storage technology, although some might fit better than others. Also, regarding your question on "core data or sqlite", you can use Core Data with an SQLite database as a backend (way easier than accessing raw SQL). You can also use other backends with Core Data: binary and XML.

I want to developed iphone application in which i want to track another iphone on google map with in 10km region what kind of API can i use please tell me
Thanks
You'll need the device you're tracking to tell you its position. That means that it'll have to be running some app (possibly the same app) to get its position using Core Location. Then, it'll have to provide that information. As Richard Ross points out in his comment, you could do that using GameKit. Another approach would be to have the device send its location to a server that you create, perhaps using a web service. Your device would then query the server to find out the location(s) of device(s) it cares about.

I'm Curious about how all the ad mechanism works.
Let's say I publish my app using 5 networks (adMob,inMobi, etc...).
Each network gives me a slice of code to incorporate inside my initialization function, so
when the app is downloaded, the report will be sent.
Now, someone downloaded my app using one of these networks, let's say by pressing an adMob banner.
Is there a way for my app to know at startup that it was downloaded using adMob, so I won't call all the other 4 network initialization code? I don't see a point making all these redundant calls.
Thanks
Well if it is an iPhone/iOS app it's always downloaded via iTunes App Store so there is no way to see which banner network is just to download your app.
