Great URL's, also a number free iOS app examples and resources on this youtube channel (Lets Build That App) as well https://www.youtube.com/channel/UCuP2vJ6kRutQBfRmdcI92mA
Seconded on Lets Build That App. Found about it last week, and bought the subscription asap - was impressed with the quality.
However, I was an iOS dev 3-4 years ago and wanted to learn swift - so, it was a pretty smooth upgrade for me. I think whoever wants to learn iOS dev might be better off learn the basics more thoroughly and then come back to this course.
Definitely recommend visiting their list of swift blogs. Nicely aggregates different sources, as a primarily iOS dev, it's a great way for me to catch up every once in a while on the dozens of blogs I don't want to follow daily.

Most topics get sufficient coverage. If you don't mind paying a small monthly fee, Ray Wenderlich's site has lots of tutorials that are well maintained. Plenty of free examples too:
