I get this error, verbatim, when trying to build and install to a device.

This is my environment:

• Xcode 8
• El Capitan

Has anyone run into this problem? How did you solve it?

Thank you

Go to Xcode Preferences -> Accounts tab -> Double-click your team name -> Click the + at the bottom left of the dialog box that appears -> Select iOS Development.

This will create a new development certificate that will allow you to install and test on your device.

go to your apple developer site and download the signing certificate. Once downloaded you should be able to click and it will auto do its thing and should be good after that
