## Discussion

Discussion For a list of possible values, see HKBiologicalSex. If a person hasn’t set their biological sex or if they’ve denied permission to read the biological sex, this method returns an HKBiologicalSex.notSet value. note: In Swift, this method returns a nonoptional result and is marked with the throws keyword to indicate that it throws an error in cases of failure. You call this method in a try expression and handle any errors in the catch clauses of a do statement, as described in Error Handling in The Swift Programming Language and About Imported Cocoa Error Parameters.
