iOS Question macOS High Sierra 10.13.4 simulator error

[zak]

Hi. I get the following error on my macbook (macOS High Sierra 10.13.4) when trying to compile via simulator: Simulator cannot be opened because of a problem. Check with the developer to make sure Simulator works with this version of macOS. You may need to reinstall the application.Be sure to install any available updates for the application and macOS.

on my Windows10 laptop with B4I version 4.81 I get the following error when I press Run:
The following build commands failed:
CompileAssetCatalog Payload/dobona.app Images.xcassets

this error only appeared after I updated my macOS. Even after reinstalling B4I on both windows and mac I m still stuck.

I fear that you'll need to update XCode too to the latest stable version. This is a problem of incompatibility with the macOS update.

Which version of Xcode is installed? For now you should use Xcode 9.2.
