I have a schema building an instruments package. After updating to Xcode 13.3 it fails with:
BuildInstrumentsPackage ....instrdst...
/Applications/Xcode.app/Contents/Developer/usr/bin/instrumentbuilder ...
Assertion failed: (_columnToInterpolationExpressionMapping[column] == nil), function -[XRPackageModelingRuleSystem setColumnInterpolation:expression:definesLayoutScope:], file XRPackageModelingRuleSystem.m, line 422.
Command BuildInstrumentsPackage failed with a nonzero exit code
I don't have a clue what's going wrong. Any hint?
