Unable to install api file from another developer through xcode [duplicate]

Question

This question already has an answer here:

"a valid provisioning file for this executable was not found" in XCode (1 answer)

Closed 8 years ago.

I can install my app written for myself through XCode smoothly. However, I can not install an app, a ipa file, given from my friend through Xcode => Window => Organizer => My iPhone => Applications => Add .

There is a error message named "a valid provisioning file for this executable was not found."

Does any know why I can only install an app written for myself, but cannot install an ipa file from third parties?

How can I do to install an ipa file? Do I need to request something else from my friend? He told me he can install that ipa file from his device correctly.

Answer 1

You do not install your friend's IPA file through Xcode.

Third party development IPA files are supposed to be installed via iTunes or through a web service such as TestFlight.

Your friend must ensure that he has signed the app himself and has used an ad-hoc provisioning profile with your device's UDID included.
