i am work with bluetooth for my app, so i want test in xcode simulator but there is no any option for start the bluetooth
I would recommend writing a BLE peripheral test injector. In other words, a class/framework which sends the CoreBluetooth peripheral rsponses to your app. Basically an internal simulator of the BLE device to which your app is supposed to interface. It is not a perfect solution but long term having an internal simulated BLE peripheral will really help with testing, writing, and debugging your code.
