can my iphone 6s have it's privacy infringed?

[Applet]

if connected to an itunes on another mac, it already has a passcode which l believe is impenetrable ?
eg can my wechat, whatsapp, or pictures, etc be seen ?

Nothing is impervious to password circumvention but someone would have to know what they're doing and that doesn't include 99% of people. However, if you sync content with your computer, someone can access some of that synced content if they have access to your machine (pictures for example).

Pictures in particular can easily be seen on any computer it's connected to - if whomever is connecting it has the code (or fingerprint) to open the phone. I use 4 different computers at work for browsing and transferring the pics off mine using Picasa and sync it with iTunes on a Mac at home.

Don't leave your phone laying around nor let others borrow it.
