Jens,
Thanks very much for the suggestions. Re the possible error in my Obj-C code: Apple's documentation for NSTextTab shows 2 ways to create an NSTextTab; the first is initWithType:location: (which is what I used in my Obj-C code) and the second is initWithTextAlignment:location:options: Further down in the docs, there is a table showing the correspondence between alignments and tab stop types.
In my swift code, I’ve tried just about every permutation I can think of to get the type of tab or alignment that I want, but to no avail. It occurred to me that perhaps swift 1.2, which is what I’m using, might not work; I’ll give swift 2 a try.

(The Obj-C code you’re porting seems to be wrong, but it probably doesn’t matter because the correct enum has the same numeric value…) Command-click on NSTextAlignment and you’ll see the enum value you want is called just ‘Left’.
