swift_build_log_parser.rb

swift_build_log_parser.rb is a script for parse xctool build-log to analyze swift source compile time. The usage is explained like this:

First, Add -Xfrontend -debug-time-function-bodies to Other Swift Flags

$ xctool -workspace './xyz.xcworkspace' -scheme 'SchemeName' -jobs 1 clean build | tee build_in_detail.txt
...

$ cat build_in_detail.txt | perl -pe 's/\x1b.*?[mGKH]//g' | ruby swift_build_log_parser.rb
