Debug on device iphone error pipe broken?

I have a sample app i have installed all the provisioning profile needed and 开发者_C百科now i am debugging it on device.But when i want to install another app with the same provisioning profile it overwrites the one before it or it gives me an error like pipe broken! Can anyone help me?

Do your apps have the same app id? com.myCompany.myApp? If so then one will always overwrite the other. That's how the device identifies which app is which.

As for broken pipe, try restarting the device and xCode.
