Error in making the build [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

I have prepared the build for the iPhone app that I have recently built.

开发者_C百科The built had been successfully created but it is not being installed on my device.

I am not able to figure out the problem.

Can anyone please suggest me what might be the problem.

Thanks.

Since your error is

A valid provisioning profile could not be found

This means that you have not (correctly) installed a provisioning profile.

You cannot deploy an app onto a device without a valid provisioning profile. To obtain one, you must first register with Apple and pay them $99. Then you can create a profile through the developer portal and follow the detailed instructions to load the profile into Xcode, and subsequently install it and the app on the device.
