I'm wading into Core Data, and starting with the Core Data books by Marcus S. Zarra, I've uploaded the sample (so far) to Grokking-Recipes on github. My intent was to create a Swift sample but so far it's Objective-C.
The problem is getting it to compile. The ibtool uses all memory until I kill off the Xcode and process(es). It's pretty simplistic but I'm presuming something is wrong.
Of course I'm using newer tools - Xcode8.3 / OS X 10.2.5, so there've been a few deprecations etc but otherwise it follows the book's sample.
Perhaps something new must be done to compile this ?
