Mobile Apps’ 2 Camps: Android Kotlin vs iOS Swift

Today mobile apps world is divided into 2 camps:

  • The original Apple iOS camp with 2000s ObjectiveC (improved version Swift from 2015), and
  • The Google Android with 1997 Java “JVM” (improved version Kotlin from 18 May 2017).

Both improved languages (Swift & Kotlin) use Functional Programming features eg. “Type” = Category Math, Data immutability (can’t change at run-time for safe concurrency), execution by composition of “componentised” Functions, including ‘advanced’ aka ‘higher-order’ functions eg reduce, map, filter, etc… which are Category-Math Functors, ‘Monoids’ and its cousin ‘Monads’ for handling side-effects (printl, update database, error msg…).

From 2018 we see these 2 mobile camps unifying into 1 language independent of vendors like the Fortran/Cobol in early 1970s, but which one ? may be one of the “Grand-Fathers” of the “Pure” Functional Programming Haskell (1993) would be adopted by an independent consortium ala W3C Consortium (WWW).
