Crash on '+[SimDeviceType supportedDevices]: unrecognized selector in Xcode 8.3

[vmaraccini]

It would seem that this method has been removed in Xcode 8.3 (after it was deprecated in 8.1): [SimDeviceType supportedDevices]

This causes a weird crash while trying to run the tool because of this assertion:

NSAssert([supportedDeviceTypes count] > 0, @"There are no available devices that support provided sdk: %@. Supported devices: %@", [runtime name], [[SimDeviceType supportedDevices] valueForKeyPath:@"name"]);

Here's the full stacktrace for completeness:

I believe this might be related to an issue I submitted ( #729 ) as well.

I will take a look. Anyway xctool crashes after printing this error message. You've provided wrong simulator name.
