Signer not valid error

Question

I\'ve created an ad hoc build of my app and would like another person to install it. I have their device ID (two actually) in the provisioning profile. My certificate is t

Answer 1

I got this error by doing something dumber than anyone else has posted. I added new devices to the profile, but forgot to download the updated version, add it to Xcode, and point the project to it. When I set it up properly, testers were able to install the app fine.

Answer 2

Here's another fun one.... if you have separate entitlement files for iphone and ipad, make sure you set the target for the file for each specific build...otherwise it won't show in the build and you'll get this error

Answer 3

I arrived here because I had the same problem as the OP. It indeed turned out that I didn't have the UDID in the entitlements file, even though I'm sure I used refresh in the XCode organizer. Another refresh made no difference.

In the end I removed all provisioning profiles and then did a refresh. Things now work.

I have no idea whether this is a glitch in my setup, or an operator error. But just in case anyone else finds themselves in this situation: it may pay to remove your provisioning profiles and then do a refresh.

Answer 4

I had the same problem as the OP too. Dumb mistake: I accidentally dropped the last two digits off the device I was attempting to ad hoc distribute to when I registered it as a device.
