Many developers spend months consuming random tutorials, watching disconnected videos, and jumping between

How Can I Recover My iOS Skills? Many developers worry that they have "lost" their iOS skills. Perhaps they moved into management. Perhaps they spent several years maintaining legacy code. Perhaps they changed jobs and stopped working with Swift every day. Perhaps life simply became busy and coding moved down the priority list. The good news is that most developers have not actually lost their skills. They have lost familiarity. There is an important difference. Knowledge tha
