Edit: just went over to the forums and read this exciting tidbit:
“ Scapple 1.4.1 is also a milestone in two ways:
A swathe of the core code has been updated from Objective-C to Swift, Apple’s modern programming language. The changes we’ve made in the background pave the way for Scapple’s future.
This is the first Mac release that I didn’t code entirely myself. In fact, the entire update and Swift changes are down to our new(ish) coder, Ian.”
