Instruments crashes on startup (Appium 1.3.3)

Instruments is crashing for me on startup, using iOS 8.1 on a mac with Xcode 6.

This isn’t a new issue, but I thought that this would be fixed by appium 1.3.3.

Console output:

[shiyimin]

it seems that check “Use Native Instrument Library” on Appium iOS setting panel fixes this issue.

Even I was facing the same issue, the simulator was getting crashed and was not launching , but when I saw @shiyimin 's comment and his resolution worked, simulator loads now without any crash,if I check the “Use Native Instrument Library” on Appium iOS setting panel.

Thanks a lot @shiyimin
