v1.1
Use $SWIFTSHELL_FRAMEWORK_PATH instead of $DYLD_FRAMEWORK_PATH in the swiftshell launcher script.
Because of this change in El Capitan:
Spawning children processes of processes restricted by System Integrity Protection, such as by launching a helper process in a bundle with NSTask or calling the exec(2) command, resets the Mach special ports of that child process. Any dynamic linker (dyld) environment variables, such as DYLD_LIBRARY_PATH, are purged when launching protected processes.
