In my app I want to notify the user for any internet notifications such as switching from ethernet to wifi or no reachability in System it has to automatically notify my app. I know how to do in iphone app using reachability example but the same doesnt work for Mac OS X Cocoa app. How to implement this using Objective-C in my cocoa app?
Reachability exists on Mac just like iOS. Some of the flags are a little different, but the basic approach is the same. See SimpleReach.

I want my watch app to be identified by my paired iPhone.I am using CoreBluetooth Framework to implement this. I am transmitting bluetooth signals from my watch app and trying to receive the signal in my iPhone app. I am using the same concept as apple has shown in its sample code (https://developer.apple.com/library/ios/samplecode/BTLE_Transfer/Introduction/Intro.html#//apple_ref/doc/uid/DTS40012927) , the only difference is that my transmitter is the watch app.
Issue
I am unable to detect watch app in my iPhone. I have made sure that all of my hardwares are configured properly and I am configuring the Core bluetooth delegate methods properly. I also suspect if this method will be feasible with iPhone and apple watch.
All suggestions are appreciated. Thanks in advance
This is not possible because your WatchKit app runs as an extension on your iPhone and therefore all Core Bluetooth bluetooth signals are sent from the iPhone itself to itself.
Access to Core Bluetooth on Apple Watch lets your apps bypass the phone and connect directly with the Bluetooth in Apple Watch. Access Core Bluetooth to connect directly with accessories. And with Apple Watch Series 3, your apps can take advantage of built-in cellular and altimeter capabilities.
Please note, since watchOS 6 it's possible to use CoreBluetooth on watchOS.
Check for more informations this link "Creating Independent watchOS Apps"
Be aware there are still some limitations using CoreBluetooth in watchOS for example:
The minimum connection interval is 30ms instead of 15ms (for iOS devices).
The Apple watch can only operate as a central device.
The Apple watch can only be connected to two peripherals at one Time
The peripheral gets disconnected when the app goes into the background.
Maybe this will change when watchOS 7 is out.
So basically what I want to do as the title says is when I have a bluetooth connection established to my iOS device, an application should automatically start. How can I do that?
Observation: GameKit is used for the connection.
Without jailbreaking the device and writing/installing a Springboard plugin, this isn't possible in iOS.
There are no Apple-provided APIs for launching apps and developers are only able to write code that runs when their app is launched by a user.
i'm an iOs developer and I actually need to make a mac application that use bluetooth framework to connect to another device (not iOS device).
I'm actually showing a modal view showing the connected bluetooth device with IOBluetoothDeviceSelectorController and I get the user choice with [modal getResults] but I don't know how to initiate the connection with the selected device and I can't find a simple way to do it on the mac dev library.
is anyone know a tutorial or sample code that could help me advance in my project?

The Mac Developer Library has two sample Bluetooth projects; connecting to a health thermometer and connecting to a heart rate monitor. There is also video available of the Advanced Core Bluetooth WWDC 2012 session.
I am new to developing for the iPhone and would love some advice on an app i'm trying to develop.
Is it possible to send commands to an app on iOS 3.2 from OS X using AppleScript. The iOS app will display an image and run a small script when it recieves the appropriate command from the client software running on a Mac Mini. The devices would communicate over an a closed WiFi network.
Before I continue down this path does anyone have any advice on how to setup the communication (i.e. get the app to run in the background and listen on a designated port).
I don't know the full process but I know that various apps do this one way or another, such as 1password and desktop remote mouse apps. I think that CocoaAsyncSocket will help. An alternative to having the iOS app listening on a socket is to open a connection from iOS to OS X and then persist it. You can then send data either way through the connection.
Is this possible?
I want to be able to press a button on the iPhone app and something happens to the Mac app. Maybe via 3G and wifi.
Any ideas?
Yes, both Mac OS and iOS support numerous network APIs, including CFNetwork. You could use Bonjour to let the iPhone discover the Mac (or vice versa).
