asbd.memory.mChannelsPerFrame  compiles, so that's probably what I was  
after.

asbd.memory().mChannelsPerFrame I think should work - untested but memory() 
gives you the underlying object.

dereference UnsafePointer

[Jan E. Schotsman]

Hello list,

How can I dereference an UnsafePointer in Swift?

For example

let asbd =  
CMAudioFormatDescriptionGetStreamBasicDescription( formatDescription )


let numSndChannels = asbd->mChannelsPerFrame // this fails to compile,  
of course


Do I need to write an accessor in a .c or .m file?

TIA,

Jan E.
