anyOf(requirement:)

Declaration

static func anyOf(@ProcessConstraintBuilder requirement: () -> [any ProcessConstraint]) throws -> ProcessCodeRequirement

Discussion

This operation will throw ConstraintError.duplicateKeys if more than one constraint of the same type is found in the same logical grouping. For example the following snippets will throw:

    let req1 = try ProcessCodeRequirement.anyOf {
        SigningIdentifier("com.apple.ls")
        SigningIdentifier("com.apple.ps")
    }
    let req2 = try ProcessCodeRequirement.anyOf {
           SigningIdentifier("com.apple.ls")
           allOf {
               SigningIdentifier("com.apple.ps")
           }
    }
    let req3 = try ProcessCodeRequirement.anyOf {
        SigningIdentifier("com.apple.ls")
        anyOf {
            ValidationCategory(.platform)
            SigningIdentifier("com.apple.ps")
        }
    }

The second requirement throws because a single constraint within allOf has no effect and so it gets lifted to the higher logical group. Similarly, the third requirement throws because an anyOf operation nested in an anyOf operation has no logical effect, so all of the constraints in the nested operation get lifted into the higher level group. On the other hand the following snippet will not throw:

    let req4 = try ProcessCodeRequirement.anyOf {
        allOf {
            SigningIdentifier("com.apple.ls")
            ValidationCategory(.platform)
        }
        allOf {
            SigningIdentifier("com.apple.ps")
            ValidationCategory(.platform)
        }
    }

In this requirement, both allOf operations provide different requirements that are each options., so the two groups are considered separate.
