Tell us about the problem

When run tns debug ios it tries to open Nativescript Inspector and immediately closes it and throws an error.

Which platform(s) does your issue occur on?

iOS

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

• CLI: 3.3.1
• Cross-platform modules: 3.1.1
• Runtime(s): tns-ios: 3.3.0

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

I'm trying to debug nativescript tutorial app nativescript-template-ng-tutorial, and when run tns debug ios it has problems.

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

On 17th second it opens and closes the nativescript inspector at the same time.

Hi @shoudaos

To be honest I have no idea what can cause the problem, but as temporary workaround I can suggest you using tns debug ios --chrome.

We will update the issue once we have idea what can be wrong.

btw, Can you reproduce the same issue with hello-world project?
Can you also try npm cache clean before debug?

[dnadoba]

I have exactly the same issue. The inspector crashes because of the missing symbol _CTFontCreateForCSS

I can reproduce the issue with the hello-world project.
npm cache clean --force does not solve the problem.

tns debug ios --chrome does work but always creates a new URL.
I have to copy & paste the URL into chrome after every code change. Do I miss something?

@dnadoba
changing the URL when run tns debug ios --chrome is known and this is how it works right now.

Same issue here - missing symbol _CTFontCreateForCSS

Occurred after updating to the latest Xcode.

[shoudaos]

@anthonyball Do you mean 9.1 version? What version of XCode did you have with working inspector?

[anthonyball]

It was 9.0 I think. The update of Xcode happened at the same time as upgrading from Sierra to High Sierra so it could have been that or a combination of the two.

[shoudaos]

@anthonyball, I updated xcode to 9.2, nothing changed, so will try to downgrade to 9.0

[anthonyball]

Same here, let me know if the downgrade does the trick please

[shoudaos]

@anthonyball what can I say. Downloaded xcode 9.0 xip archive, then installed it, and when run tns run ios it can't find any ios simulator. i tried tns run ios even with --device simulatorID, nothing works.
When returned to 9.2 version all began to work again. But the issue with Inspector was remained.
It makes me crazy. I don't know what to do

[shoudaos]

@anthonyball can you try to downgrade yourself? maybe i made mistake somewhere

[brandontulsi]

facing same exact issue

[anthonyball]

Going to take a look at this tomorrow and see if downgrading to Xcode 9 will work or not. I’ll let you know.

[anthonyball]

Couldn't get an emulator loaded in Xcode 9 either when I downgraded. Nor could I get it to fire when loading the app straight onto a physical device. Currently going back to 9.2 and I expect the _CTFontCreateForCSS issue to remain.
