Problem calling an Objective C method from Swift

I am trying to call the following Object C method from Swift but can’t seem to pass in the string in the correct format. It appears to be expecting an UnsafeMutablePointer<NSString?>. Any help would be appreciated.

  • (BOOL) Check:(NSString* __strong *)postcode

@hi sunilsharmax,
Hope this problem is resolved, the evolution of Swift has better C-API handling
