I work mainly with Swift nowadays and some stuff like String handling is way more complex than in other languages like C#. Since I'm not doing a lot of series-of-characters manipulations in my daily work I need to rely on Google and a friendly IDE that highlights errors and warnings and provides autocompletion through get through tests like simple anagrams. Codility and co have neither. Nothing worse than unsuccessfully sweating through an exercise for 20 minutes on something super simple, only to fix it within a Playground in a minute just because you get errors, warnings and autocomplete.
