I have gone through the process of learning swift and I have a basic objective c background, but it would be really helpful if all of the guides would be ported over to swift. any word when they will?
When will location and map programming guide be adapted to swift?
It may help to realize that Swift is still early in it's growth cycle. It makes little sense to flesh out docs when significant deprecations are still the rule.
Give it a few more years, then you can get as comfortable with reference materials as you like. In the mean time, you can help move things forward by visiting swift.org and participating in it's evolution. Nothing like an active role to stay on top of progress.
