ios - Weird erros "Sanbox deny iokit-get-properties" in IOS8 -

i have strange behaviour when debug ipads on app i'm programming, , i'm pretty sure appeared after updating of production ones ios8.

i using multipeer connectivity, , tried debugging random disconnections, ended seeing device's console long. noticed there bunch of them before or after disconnection (by bunch mean 2 dozen hundreds of lines).

also, app uses background services, don't know if it's related, required me edit app's configuration (in xcode) enable updating certificate.

so, why these "sandbox deny iokit-get-properties" messages appearing?

thank you.

this should not happening unless trying access restricted iokit properties app. sandbox on ios doesn't block iokit , io registry, looks apple has selected specific nodes , values should denied. you're seeing here values got denied, it's possible other values getting through okay.

if not doing iokit directly, might multipeer connectivity framework that's making calls, in case issue fixed now.
