When viewing the peerCertificateChain for a SSL connection it will not include the root certificate if it is trusted.

If you use the securesocketclient example to connect to incyte.wickr.com without the attached certificate in your keychain then clicking the padlock icon will show two certificates (after you get a warning about it not being trusted). The root and the leaf certificate.

Once you add the attached certificate to the keychain and it is marked as Always Trust, then connecting will only show the leaf certificate in the peer certificate chain. The root one no longer shows up.
