# In a world where everything has to be bigger, faster, higher and more,
# users seem to have developed the expectation that the bigger the software
# package, the better the software. However, if you fill up your binary with
# useless data, the app store size might be too high and your app will
# require download over wifi.

# The following script can be added to your Xcode target as a shell script.

GTK3 Linux Swift header issues
View gtk3-swift-package-issues.scala
/**
I tried to get GTK running with Swift. To run this, a Linux machine with a working GTK3
installation is needed (could also work with OSX && brew install gtk+3, however I did not try that);
i.e.
`sudo apt-get install libgtk-3-dev`
Initially I tried with GTK but since GTK has dependencies to a lot of other things, I tried something
simpler, i.e. in this case GDK which has only dependencies to X11.
