> do you really think you can call yourself an iOS developer when the only way you truly know how to create apps is with React? I totally agree with you, but does it matter in the grand scheme of things? Look at web developers that only know frameworks. They may only know jQuery or only know Rails, but if they're still getting shit done, does it ultimately matter? There may come a day where that developer is required to go deeper than the lib/framework allows and they may be exposed or may be forced to learn more or they may drown because they never learned to swim. This is interesting to me because it brings up the question of how important is mastery when there are deadlines?
