I upgraded the Xcode to version 7.2 (7C68).
After the update I can no longer install the project under development for testing on my iPad.
This message appears:
App installation failed: An Unknown error has occurred
I already tried to give a clean but unsuccessful.
In a simulator the project is installed normally.
For testing purposes I created a new project and it is installed both in the simulator and on iPad.
Have any log on Xcode for me to try to find the problem?
Delete the app installed on your iPad and rotate again

I already did that. I wonder why the downvote, who gave could help me improve the question?

Strange, every time it happened cmg I simply uninstalled and worked, which error code appears along with the message?
– Jeferson Assis
@Jefersonassis that’s the problem, no code appears, only the unknown error message. I already tried to follow the Technical Note TN2319, unsuccessfully too. I have cocoapods in the project, but I think this shouldn’t be the problem.

Already tried to install on another device?

There is a problem with the digital certificate on Xcode after the update. I don’t know if that’s your case. Further information: http://stackoverflow.com/questions/5932522/codesign-error-certificate-identity-appearing-twice/12633127

I have not yet tested on another device. @Ccastro this is not my problem. I have already reset my iPad and installed the latest version of Xcode. Apparently the problem is not with Xcode, because I have three different versions and the same problem occurs. I’m thinking it’s some configuration file, since a new project works normally on iPad. I didn’t want to move my current project to a new project because I didn’t want to miss the GIT track.

Guys, I got it to work. I just did so much that I don’t know how it worked. I have deleted all development keys that are in Applicationn/Utilities. I removed all the folders that are in /Library/Developer/Xcode/Deriveddata and finally I cleaned the project again. Only at each stage I tried to build, until one hour worked. Maybe it’s a bug? I saw that all the reports were ok before installing the debug app on iPad and in the attempt to install appeared the error described in that post.

The problem happened again. I deleted all the folders from /Library/Developer/Xcode/Deriveddata again and it worked normally.
