What to expect from Marzipan: It’s clear that Apple’s 2019 WWDC is going to be a doozy

“It’s clear that this year’s WWDC is going to be a doozy,” Craig Hockenberry writes via Iconfactory. “Of course I’m talking about Marzipan, a technology Apple introduced with few details during last year’s Keynote. We knew that some apps in Mojave used the new technology and that was about it.”

“Thanks to the hard work of Steve Troughton-Smith, we have a much clearer view of what’s happening behind the scenes with application architecture and available APIs,” Hockenberry writes. “It’s likely that getting your iOS app to run on a Mac will just be a matter of flipping a switch in Xcode. Steve Troughton-Smith has been converting apps using nothing more than a Simulator build, his marzipanify tool, and a lot of clever tweaks with frameworks.”

“It will be exciting for a lot of developers, including yours truly, to press that button. But it’s also important to temper this enthusiasm with reality: that build setting is just the first step on a long and complicated road,” Hockenberry writes. “Good interaction doesn’t come for free.”

MacDailyNews Take: Yes, get ready for some growing pains that run the gamut all the way up to severe from non-Mac developers bringing their wares to the Mac for the first time. But, this’ll be fun – we promise! The Mac is all about experimenting and trying new things and, anyway, over time, it’ll all shake out and we’ll be back to quality apps that look, act and work as longtime Mac users expect.

We love it when our old predictions begin to come true! Miracles do happen:

Think code convergence (more so than today) with UI modifications per device. A unified underlying codebase for Intel, Apple A-series, and, in Apple’s labs, likely other chips, too (just in case). This would allow for a single App Store for Mac, iPhone, and iPad users that features a mix of apps: Some that are touch-only, some that are Mac-only, and some that are universal (can run on both traditional notebooks and desktops as well as on multi-touch computers like iPhone, iPad, iPod touch, and – pretty please, Apple – Apple TV). Don’t be surprised to see Apple A-series-powered Macs, either.MacDailyNews Take, January 9, 2014

  1. Cool! Excellent and awesome! This will shut haters like AppleCynic and shiityzen x right up!

    Except those losers won’t shut up, they will keep posting their hatred.

          1. And why should they be expected to do that? You either buy into their concept or not, mediocrity for the sake of some nebulous alternative concept of ‘universality’ is not a real choice at all, especially when those who call for it will only find other reasons not to buy into it. It’s a pointless task chasing after them it just gets political where the tribal attitudes predominate as you demonstrate so well.

        1. “[O]nly without the insecurities and bloat, anyway this is for apple operating systems fer [sic] goddsakes [sic]!”

          Java did not start out with the “insecurities” or “bloat”. Neither did FORTRAN, COBOL, or even C. They all evolve and add things developers want, which cause unintentional consequences in the compiled and linked code. It is almost certain that this compiler/cross compiler using variants of Swift will be no different 10+ years from now.

    1. Apple’s WWDC will be declared as boring and well-behind the rest of the industry. They’ll mention how Windows already runs on ARM processors and has for years. I can assure you that whatever Apple announces will be met with yawns and said not to be meeting expectations.

      I’m an end-user so the WWDC isn’t something I’m all that interested in. I doubt Apple will be able to announce some game-changing tech but that doesn’t happen very much, anyway. I’m mostly interested in Apple making decent, long-lasting hardware products, that if necessary, can be upgraded and easily repaired.

      I wouldn’t mind being able to run iOS apps on a desktop Mac, but it’s not something I really need. It might be kind of cool to run OSX on an iPad Pro but that’s also not something that I need to do.

  2. Hmmmm, the name Marzipan.
    When I worked for BMW North America, my boss who was from Germany, went home for a vacation and when he came back, he brought me what he assured me was a wonderful treat called marzipan. Honestly I had never heard of it. I unwrapped a piece and took a bite, thought it was pos
    sibly a potato or something, no particular taste of any sort.

    I looked it up and found the definition was “A sweet, yellowish paste of ground almonds, sugar, and egg whites”

    I pretended that it was wonderful and that was the end of that.

    So does that mean that Marzipan will be some sort of bland blending of operating systems, or just a hipster attempt to provide an air of sophistication by using a word that the average person neither knows or cares about? “only us cool people know what it means”

    I dont’ care what the silly label reads, just don’t mess up or water down OSX.

    1. sorry about that accidental space, my finger must have hovered over or accidentally brushed the side of, or “gestured” at some key of a Macbook Pro, which I love except for the keyboard, and dongle hell.

  3. I’m really happy to read elsewhere that AppleScript will work in Marzipan apps. AppleScript is one of the most underrated, most productivity-boosting features of macOS.
