Reduce Xcode build times

source https://coderwall.com/p/1p4mha/reduce-xcode-build-times

• Try remove ~/Library/Developer/Xcode/DerivedData/

$ rm -rf ~/Library/Developer/Xcode/DerivedData/*

• Creating a 2 GB volume RAM disk via the Terminal:

$ hdid -nomount ram://4194304

• hdid outputs the device name of the RAM disk. Change the number instead of the 'N' for newfs_hfs and diskutil commands.

$ newfs_hfs -v DerivedData /dev/rdiskN
$ diskutil mount -mountPoint ~/Library/Developer/Xcode/DerivedData /dev/diskN
