Question

Is there anyway to add an array of HKWorkouts to UserDefaults or do I have to save the array in core data?

Answer 1

HKObject and its subclasses conform to NSSecureCoding, so you can convert an array of them to Data using NSKeyedArchiver. See the NSKeyedArchiver documentation for more details.
