TIL that Icon Composer uses Garbage Collection and thus can't run on Sierra. Dammit, I was still using that, mostly for quick scaling.

@mjtsai @petermaurer FTR it took quite a while before I jumped on the ARC-train as well.

@mmunz@petermaurer I have yet to do so. If one has working, tested MRR code, and Swift is the future, ARC Obj-C doesn’t seem worth it. - View other replies

@mjtsai@petermaurer but if you’re updating that code, it frees up your mind from a menial task to focus on more important aspects of code. - View other replies

@mmunz@petermaurer If I’m doing major updates to the code, I would just rewrite it in Swift. -
@mjtsai@petermaurer Right, if targeting >= 10.9, Swift is a good option for major rewrite stuff.
