Please, provide the details below:

yes

Tell us about the problem

When a project build fails because of a bitcode compilation, it will continue failing even if you use the next CLI version containing the barcode fix and you have to delete the platforms folder.

Which platform(s) does your issue occur on?

iOS

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

• CLI: 4.1.2
• Cross-platform modules: 4.1.2
• Runtime(s): 4.1.2

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

1. Clone the nativescript-ui-listview repo
2. cd src && npm run build && cd ../demo
3. tns run ios --provision YourProvisionHere (you need to test on a real device in order to get the bitcode error)
4. npm i nativescript@4.2.0-2018-07-10-11964 -g (containing the bitcode fix)
5. repeat step (3)

expected: a successful build
actual: a failing build
