List of all iOS devices produces an error

[akanass]

Hello,

• Overview of the issue:

I want to list my iOS device to deploy application on it but I occur an error when I want to list it with:

$ tns device ios

CLI displays these messages:

Cannot read property 'id' of undefined
# device ios
┌─────────┬─────────────────────────────────────────────┐
│ Usage   │ Synopsis                                    │
│ General │ $ tns device ios [--timeout <Milliseconds>] │
└─────────┴─────────────────────────────────────────────┘

Lists all recognized connected iOS devices with serial number and index.

### Options

    * --timeout - Sets the time in milliseconds for the operation to search for connected devices before completing. If not set, the default value is 4000. 

Sending exception report (press Ctrl+C to stop).....

I've tried to display all devices with only:

$ tns device

CLI found my device but if no iOS simulator was started, this error occures:

Error: There are outstanding futures. Construction call stacks:

If I launch an iOS simulator all is fine.

• Telerik NativeScript version:

2.4.0-2016-09-21-6710

• System configuration:

Mac OS X 10.11
iOS 10 and XCode 8

Thanks for your attention.

If I restart my Mac, all is fine.

I think that tns keeps in memory all devices and produces an error if it doesn't found an old element

[rosen-vladimirov]

Hi @njl07 ,

Can you execute

tns device ios --log trace

and send us the output?

Thanks in advance for your help.

[akanass]

After rebooting my Mac, I can't reproduce this error and all it's working, sorry for the mistake.

[rosen-vladimirov]

Hi @njl07

Thanks for reporting both of the issues. In fact we've found what's causing them. You can easily reproduce the issue by starting the simulator, closing it and immediately call tns device ios.
CLI is checking for a living process called launchd_sim which needs some more time to die. However when we try to get more data about the simulator, we receive the Cannot read property 'id' of undefined error.
We've prepared a fix for this issue and it will be included in the next official release.

Thanks again.

If I try to do livesync when this problem occurres, action crashes and I must to restart my Mac to can perform my application.

@njl07
Can you execute
xcrun simctl list while the simulator is running and send us the output?

When livesync can be performed, I've this error:

Unable to start service com.apple.mobile.installation_proxy. Result code is: 3892314239

To reproduce it, just connect a device like an iPhone, type:

$ tns device ios

Deconnect the iPhone and reconnect it, type:

$ tns livesync ios --device deviceID --watch

Error occures and I must restart my Mac to perform the application livesync

[TsvetanMilanov]

@njl07 the issue with Cannot read property 'id' of undefined is fixed, the problem was with the process called launchd_sim (@rosen-vladimirov described it in one of the previous comments). As for the second issue with Unable to start service com.apple.mobile.installation_proxy. Result code is: 3892314239 check this issue #1398.
