App hangs on unhandled exception when launched with `tns run`

Please, provide the details below:

When you run a {N} application on a device using tns run and an unhandled ObjectiveC exception is raised, then the UI on the device freezes and the application doesn't terminate.

Did you verify this is a real problem by searching Stack Overflow and the other open issues in this repo?

Yes.

Tell us about the problem

The issue seems to be related to the way the application is started by the CLI. It uses lldb to launch and debug it on the device. Whenever an unhandled exception is detected by the debugger it breaks execution and awaits for commands on stdin. The CLI however doesn't send anything and the app appears as if it has hung.

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• CLI: 3.2.1
• Cross-platform modules: 3.2.0
• Runtime(s): 3.2.0

Please tell us how to recreate the issue in as much detail as possible.

Launch an application which causes an unhandled ObjectiveC exception using tns run ios.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

Put this line of JS code in your application (e.g. on some button's click event):

new NSString().characterAtIndex(10);

Bắt đầu bằng cách tái hiện sự cố với tns run ios bằng ngoại lệ được cung cấp new NSString().characterAtIndex(10);, sau đó theo dõi cách CLI khởi chạy ứng dụng iOS thông qua lldb. Công việc được hoàn tất khi một ngoại lệ Objective-C chưa được xử lý không còn khiến giao diện thiết bị bị treo và ứng dụng kết thúc hoặc CLI xử lý trạng thái trình gỡ lỗi một cách phù hợp.
