Can't build iOS app from XCode - Error (branch new-mm-demo) about kmm-production-sample

[KaterinaPetrova]

Hey @ultraon! From what I can see from the error log, JAVA 1.8 is used for building KMM module from Xcode. Please try add
JAVA_HOME = /usr/local/Cellar/openjdk@11/11.0.10/libexec/openjdk.jdk/Contents/Home to the Run Script Xcode build Phase (before calling embedAndSignAppleFrameworkForXcode Gradle task). If this helps, then JAVA_HOME is not configured properly for the shell used in XCode

Hello, @ultraon. I just had the same problem.

The problem in my case was the following:

• XCode relies on a program called /usr/libexec/java_home to obtain the JAVA_PATH, but as I installed my java jdk via a third party sdkmanager (sdkman), java_home could not find the path properly. This wiki explains why it happens.

The solution:

• I had to, manually, open XCode > Preferences > Locations > Custom Paths and add a custom path with name JAVA_HOME pointing to my current JAVA_HOME directory.
