For two weeks now I have been getting my hands dirty with iPhone / OpenGL ES 1.1 development on my iMac. A week ago my wife got me a new Macbook Pro for my birthday and we have been inseparable. Just like a kid obsessed with its new toy, I can’t resist the urge to mirror any development tools and configuration that I have on the iMac into the Macbook Pro, so I can keep developing while at the same time accompanying my wife watching TV. All was good: Xcode ran properly, iPhone SDK 3.1 (Snow Leopard) installed successfully, all certificates and developer provisioning also installed, iPhone 3.0 simulator ran without any problems, and I was smiling, but not for long. Then I selected “Device – 3.0 | Debug”, rebuilt the app, and it showed build failed – 1 error, which looked like this:
“Code Sign error: The identity ‘iPhone Developer doesn’t match any valid certificate/private key pair in the default keychain”
I was pretty sure I’ve installed all the certificates:
- Development certificate
- WWDR immediate certificate
- Development provisioning profile
Then I noticed something in the provisioning profile (Window > Organizer > Provisioning Profiles):
“A valid signing identity matching this profile could not be found in your keychain”
I looked for clues on the net long and hard, then I discovered the answer posted by Dave Camp:
The answer for my problem is: I’m missing my private key!
I took the following steps to fix this problem:
- Exported my private key from the login keychain from iMac
- Shared the private key over the network, downloaded it into the Macbook, and deleted the private key so it’s not stolen by someone (or just use a USB drive, safer and easier)
- Imported the private key into the login keychain in the Macbook (by double-clicking it). At this point it throws me some weird error but it works for sure because I can see it now in the login keychain
Voila! The build no longer returns any error!
Hope this helps some of you who encountered this same problem.
