--sdk flag not working properly when starting emulators in iOS

[manijak]

I am trying to run LiveSync on my app with specific --device and --sdk flags. But they do not seem to work out of the box.

When I try to run:
tns livesync ios --emulator --device 'iPhone 6' --sdk 9.2 --watch
I get the following error:
Cannot resolve the specified connected device by the provided index or identifier. To list currently connected devices and verify that the specified index or identifier exists, run 'tns device'.

LiveSync should start the emulator if it is not running, with all the flags applied?

If I run this:
tns livesync ios --emulator --sdk 9.2 --watch
It starts the emulator with iPhone6 and with iOS 8.4, not 9.2 as I specefied.

In order to get my livesync running with iPhone 6 and iOS 9.2 I had to do the following:
tns emulate ios --device 'iPhone 6' --sdk 9.2 --justlaunch
tns livesync ios --device 1 --sdk 9.2 --watch

So two command lines, plus I had to use --device [index] as it didn't find the device by name...

EDIT: The first command used to work fine on 1.5.2, except the --sdk flag. So now in 1.6.2 also the --device flag seems to be "broken".

@manijak ,

Thanks for reporting this. I can confirm the behavior is incorrect and we'll fix it in one of our next releases (of course you are more than welcome to submit a PR with the fix).
You can simplify the workaround by using:

$ tns emulate ios --device 'iPhone 6' --sdk 9.2 --justlaunch
$ tns livesync ios --watch

The second command will work with the iOS Simulator directly, so there's no need to specify device and sdk

Hey @manijak ,

--device option is intended to work with already attached devices and cannot start a device using specified sdk. --emulator however should do this and I can confirm that --sdk flag is not working as expected. We will do our best to fix it immediately!

[manijak]

Hmmm... This is an old issue. I am currently using the --sdk flag when starting the emulator and it works fine :) After that I just run tns livesync ios --watch and all is good

Hey @manijak,

You are right, my mistake. It seems however that we have regression with our current master branch for run and emulate commands with --sdk switch.

I'm closing the issue, we will handle this internally.

Fails again (even with {N} 2.1.0 official release):

tns livesync ios --emulator --device 'iPhone 6s' --sdk 9.2 --watch --path TestApp
=>
Cannot resolve the specified connected device by the provided index or identifier. To list currently connected devices and verify that the specified index or identifier exists, run 'tns device'.

instruments -s | grep 'iPhone 6s'

With 4.0.1 RC now you can do things like this:

tns run ios --device 'iPhone 7' --sdk 11.3 --path TestApp

To find out availalbe devices and sdks you can run:

tns device ios --available-devices
