I also started with a C++ background and did (am doing) the following:
- Read Apple's book
- Started solving Project Euler problems with Swift as first practice: https://projecteuler.net
- Figured out what I'd like to do for an App and started to code that
To keep myself motivated in the beginning I also wrote some blog stuff: http://swift.svbtle.com
thanks guys! But at the moment I've decided not to dwell on swift yet, because python has a much wider application (data etc) so I probably will work on that in the new academic year.
