unable to get device details, possibly due to recent update in shelljs version about simctl

[tzmartin]

simctl.js
LN 175: Change obj.output to obj.stdout

[mrister]

@CodeWithOz unfortunately no, I had to resort to using xcrun simctl list devices and xcrun simctl boot to run the simulator

[antares-farias]

what works for me was to directly install in the project the previews version of the simctl

npm install [email protected]

[mrister]

seem to be having the same issue also!

[CodeWithOz]

@mrister have you found a workaround for now?

[ezilox]

Also experience the same issue :(

[radykal]

I got the same issue using Cordova in Meteor. I created two meteor projects with cordova. In the first one it is working, but in the other project with the same env I got the same error as mentioned above. Now I debugged the code and it seems there is a problem with the async shell execution.

I pasted an sync call after line 166 in the code and detect that the correct output is stored in the stdout of the callback function.

     var command = util.format('xcrun simctl list %s --json', sublist);

     var obj = shell.exec(command, { silent: options.silent });

	shell.exec(command, { silent: options.silent }, (code, stdout, stderr) => {
    	console.log('Exit code:', code);
		console.log('Program output:', stdout);
		console.log('Program stderr:', stderr);
	});

    if (obj.code === 0) {
        try {
            obj.json = obj.output ? JSON.parse(obj.output) : JSON.parse(obj.stdout);
        } catch (err) {
            console.error(err.stack);
        }
    }

@radykal how bout a PR since this breaking change does not seem to get the attention of maintainer(s) here

[XtoZee]

what works for me was to directly install in the project the previews version of the simctl

npm install [email protected]

Worked for me as a temporary solution.

Could not run Cordova 10 app in simulator. Got error on "Deploing to simulator" phase. (XCode 12.4, node v14.7.0, cordova-ios 6.2.0)

Error: Unhandled error. ('[ios-sim] SyntaxError: Unexpected token u in JSON at position 0

[mrister]

@shazron @marekkalnik can anybody of you perhaps implement a fix, this is breaking.

[marekkalnik]

Sorry @mrister I have not been using this project since 2015, not much I can do to help :(

[airdrummingfool]

@shazron I've opened a PR (#31), please take a look. Thanks @tzmartin for the fix suggestion.

[airdrummingfool]

Sorry all, my original PR missed a couple of usages of output, so I've opened another (#32).

That will fix [ios-sim] Unable to parse xcodebuild version. in case anyone is seeing that.

/cc @shazron
