hi everyone. i have a problem with `ionic package build ios` on windows. I followed ionic package tutorial ([http://docs.ionic.io/docs/ios-build-profiles](http://docs.ionic.io/docs/ios-build-profiles)) and my console displays next error:

```
  id │ 37
  status │ FAILED
  platform │ ios
  mode │ release
  started │ Jul 25th, 2016 13:25:00

output:

=== BUILD TARGET KolTaxi OF PROJECT KolTaxi WITH CONFIGURATION Release ===

Check dependencies
Code Sign error: No code signing identities found: No valid signing identities (
i.e. certificate and private key pair) were found.

**BUILD FAILED**

```

But i have .p12, .cer, .mobileprovision sertificates. What’s wrong?
