A language with no promises of stability counts as a "toy" in my mind (I understand that this can be subjective, just providing my opinion).

Say what you want about Objective-C, but at least Apple stuck with basic syntax decisions.

That kind of oversimplifies things. From my reading of the Swift mailing list, many things you would consider "basic syntax decisions" will have a profound impact on the stabilisation of the ABI.

Migrating is a pain, but I'll take the Swift migration pain over the maintenance of old Objective-C code any day. Even on large projects.
