Hi,

I'm using tns 2.3.0 and trying to build and livesync a project on iPhone 9.3.2

The debug commands builds and mounts successfully but end in this message :

$tns debug ios --device <device id>

Timeout waiting for response from NativeScript runtime.

and livesync command responds -

$tns livesync ios —device <device id> --watch

Your application will be deployed only on the device specified by the provided index or identifier.

Added the platform again and restarted the device
tns device run <application id> --device <device id>
results in the same error.

Here's the

@agrawal-mohit We are not able to reproduce the issue locally. You could help us by doing the following:

• Check whether the same issue appears when using the same device on different Mac
• Check whether the same issue appears when using a different iPhone device on the same machine
• Run tns livesync ios with --log trace option and send us the log file

I have the same issue. Unfortunately don't have another Mac or iPhone, so just attached the trace. Note that the app runs on iPhone if I start it manually (tns run ios managed to install it on the iPhone, but no debugging).

For me this issue started to occur after updating phone to iOS 10.1.1.

I tried to launch app from xcode directly and got error dialog that iPhone support files are missing(maybe this error message could be reported by cli).

Update xcode to 8.1 fixed my issue.

[agrawal-mohit]

I don't have another Mac or an iPhone. But since @cuteredstorm is facing it too, I suppose the problem is at the application level.

[tzraikov]

Like @tkaarrela said, this issue could occur when deploying to a phone running with higher version of iOS than the supported by Xcode. Upgrading to the latest version of Xcode should fix the issue. We will think on improving the CLI message in such scenarios.

[jozemlakar]

@tzraikov has completely ignored the fact that I posted the trace of a case where I had the latest iPhone and latest Xcode.

[tzraikov]

I missed that, yes. One option then is that there is something wrong with your Xcode configuration. Please, could you try the following: go to the plafroms/ios/ folder in your project and open the .xcodeproj file located there. Try to start it from Xcode.

[jozemlakar]

I have tried and tried but cannot reproduce the issue anymore. I was certainly on latest Xcode and latest iOS but maybe these two were not in sync by Apple. Anyway a better message would benefit as well as instructions to test from Xcode first (in that perspective this issue is very useful).

[krisloekkegaard]

This happened to me as well while trying to run livesync. Doing a build with tns build ios fixed it. After that I was able to run livesync again.

Just ran into the same issue. Here's what solved it for me:

tns platform add ios && tns prepare ios && tns build ios && tns run ios
