vte/libvte is extremely choppy because it's hard-capped to 40fps. all terminals based on it suffer from this, so I decided to make these quick n dirty patches for various vte versions that bump the cap up to 120fps
here's a 120fps video demostration https://streamable.com/j8i0n
also a 60fps clip on twitter if your browser can't handle 120 https://twitter.com/roriicon/status/1113186464332951559

issue can be worked around by running
I recently wrestled with the clusterfuck that is iOS code signing, so here's my setup to set up a swift xcodegen project signed with a personal (free) provisioning team. this doesn't require an apple developer account, just a regular apple id.
you'll be able to build whole thing from the command line without ever have to touch xcode ever again.
this was tested with xcode 10.0 (10A255) on High Sierra
