I got the same issue "Segmentation fault (core dumped)" when I'm calling API built by "perfect web framework" using Swift 3 on Ubuntu 16.04 with Postgres Database.

And I've also tried to use "Swift 3.0", "Swift 3.0.1" to build the swift files for test. But none of them work until I tried "Swift 3.0.2 Preview 1" - "https://swift.org/builds/swift-3.0.2-preview-1/ubuntu1604/swift-3.0.2-PREVIEW-1/swift-3.0.2-PREVIEW-1-ubuntu16.04.tar.gz", then it worked! Share with you.

Also list the version I got for swift --version:

Swift version 3.0.2 (swift-3.0.2-PREVIEW-1)
Target: x86_64-unknown-linux-gnu

See that you have +r for all the swift files.

For example in my case [1], I just extracted the files [2] under / and when I tried to execute the 1 + 2 example [3] inside the swift shell, there was a segmentation fault.

This fix was to add read rights for all users with:

cd /usr/lib/swift && sudo chmod -R +r *

[1] Ubuntu 16.04.1, amd64
