This question has been asked many times on the Swahili discussion forum. The answer is "its on its way".
Last update said either the end of last month (for future readers, April '17) or sometime this month. That timeline appears increasingly unlikely, but as we have heard nothing more as yet, that's all we have to go on.
In the meantime, many of us keep checking the Swahili incubator page in hope of updates.
