'flutter drive' fails to detect iOS hardware

[rmacnak-google]

In flutter/examples/stocks, with an iPod Touch connected (that flutter run successfully detects)

stocks$ flutter drive --local-engine ~/Flutter/engine/src/out/ios_profile --profile -t test_driver/scroll_perf.dart
Starting iOS Simulator, because did not find existing connected devices.
Waiting for iOS Simulator to boot...

I believe @yjbanov has this working?

[yjbanov]

Is this still an issue? I have not taken any action on this, but it works on an iPhone.

[rmacnak-google]

Yes, flutter drive still starts a simulator instead of using my iPod Touch.

[eseidelGoogle]

Amazingly this appears to still be an issue?

I bet the problem is that "iPod touch" doesn't match _iosDeviceTypePattern.

This should be relatively easy to fix.

[cbracken]

Tested locally and this is now working. I'm unaware of when the fix was landed.
