Can't copy text from iBooks? Using The Swift Programming Language 2.2 from iBooks, i can't seem to copy the text (many lines of code from inside the book) to then test. 

Does anybody know why this is happening? In the past I have been able to copy the text from the book however now it is not letting me (it's greyed out).

For example



Here is another example of what I mean.
Highlight the passages you wish to copy. 

Then go into the show notes area by clicking the show notes icon in the toolbar. 

Select the passages you want to copy. Go to edit > copy.
