'NSMutableSet' is not implicitly convertible to 'Set<NSObject>'

I am using coreplot to plot graph in my app.
When i try to assign X-Axis label or major tick location it is throwing error though

NSMutableSet
is converted to Set of NSObject Type.
Here is how i have written my code:

xAxis.axisLabels = xAxisLabels as Set<NSObject>
xAxis.majorTickLocations = xMajorTickLocations as Set<NSObject>


The error thrown is as follows

'NSMutableSet' is not implicitly convertible to 'Set<NSObject>'; did you mean to use 'as' to explicitly convert

Answer

You should use native Swift types rather than Foundation collections when possible. This eliminates the need for casting.

var xAxisLabels = Set<CPTAxisLabel>()
var xMajorTickLocations = Set<NSNumber>()
