From 869c02ce1f635960bfc2f06bb52e2b4e17eaa199 Mon Sep 17 00:00:00 2001 From: Elias Naur Date: Wed, 16 Sep 2020 15:23:58 +0200 Subject: misc/ios: add support for running programs on the iOS simulator Update the README to mention the emulator. Remove reference to gomobile while here; there are multiple ways to develop for iOS today, including using the c-archive buildmode directly.
