# This fix should solve most of the problems with SourceKit (Not only with Swift, also with Obj-C). Such as:
#       - Not having autocompletion
#       - False errors
#
# This is just a temporal fix. The problem could eventually return.
# If that happens, just re-run this file
#
# The implementation comes from an answer in stackoverflow, which helped me a lot.
