Instant Errors

I’m loving how, in XCode and Playgrounds, it’s constantly sort of compiling or interpreting in the background so errors are being flagged as you’re working. I tried to google the proper name for this but it’s clearly so unremarkable as to be un-remarked on. I guess maybe it’s a commonplace feature of modern IDEs, but for someone who literally used to go to make a coffee when compiling a medium size Clipper, or even years later Visual Studio C++ project, it’s a revelation.

It’s so built in for me to think of errors as failures, that at first it was a quite unnerving. I was thinking “Hang on, hang on – at least let me finish typing before you judge me!”. But increasingly, I love the little second or so pause when I finish a section and wait for it to clear all the errors.
