- first i used image version “9.3.1” and upgraded yarn and node. => errors
- on announcement Xcode 9.3.1 Released for CircleCI 2.0 marc replied there is a new release with node 10.3 and yarn 1.7
- so i tried “9.4.0” => errors
- updated node on “9.4.0” to version 10.4 => still errors
can’t determine the differences between my mac and the machine with “9.4.0” => I can use xcode “9.3.0”. Just wanted you to know about the errors
