Some Developers Facing 'Several Problems' Porting iPad Apps to the Mac With Catalyst [Updated]

One of macOS Catalina's biggest new features for developers is Mac Catalyst--initially known as Project Catalyst--which Apple says makes porting iPad apps to the Mac as easy as checking a box in Xcode.

However, more work is required for the iPad apps to truly resemble native Mac apps, and Bloomberg's Mark Gurman reports that some developers have encountered "several problems" with Catalyst so far.


For example, the report claims that James Thomson had to work harder than he expected to get his popular PCalc calculator app for iPad to run well on the Mac. Thomson said the Mac version initially "looked like an iPad app floating on a larger Mac screen," so he had to redesign much of the user interface.

Thomson added that some older Macs struggle to handle Catalyst-based apps that use Apple's high-level 3D graphics framework SceneKit.

Lukas Burgstaller, developer of the RSS reader Fiery Feeds for iPad, also "ran into all sorts of walls" trying to adapt the iPad app to the Mac interface using Catalyst, but the report does not mention any specific issues he faced.

On the consumer side of things, the report notes that Catalyst results in users paying twice for the same app across iOS and macOS.

"As a user, I don't want to pay again just to have the same app," well-known developer Steven Troughton-Smith told Bloomberg. "As a developer, I don't want my users to have to make that decision."

Troughton-Smith touched on some of the issues developers are facing with Catalyst, noting that Mac versions of some apps can't hide the mouse cursor while video is playing, or may have issues with video recording, two-finger scrolling, or using the keyboard and full-screen mode in video games.

The report adds that two upcoming Catalyst apps that had been featured on Apple's website since June were removed this week, including comic book app DC Universe and the racing game Asphalt 9. It is unclear if the Mac apps are no longer planned or delayed, or if any of the Catalyst issues reported were a factor.

Netflix also confirmed that it has no plans to develop a Mac app using Catalyst at this time, according to the report.

Despite all of this, Troughton-Smith believes Catalyst is the "future of Mac app development," and he is impressed with many of the first apps. There might just be a few growing pains along the way.

macOS Catalina was widely released on Monday.

Update: Gameloft says Asphalt 9 for Mac via Catalyst has been "slightly delayed" in order to "polish the experience" and that it will launch later this year, according to a follow-up tweet from Gurman.

Home is everywhere and nowhere.
Already expected cause the project catalyst is a new stuff that Apple need to prepare for several years.
Expected after preparing for several years does not compute.

Once again, I am baffled at Netflix' contempt for Mac users. Screw you, too!
I don't know anything about netflix except they have millions of users, if that is indeed the case I have to agree with you.

One word for you: Java.
Lol, (consumer) Java.🤣

Having an iPad app look like "an iPad app floating on a larger Mac screen" doesn't surprise me. Apple may have overpromised, but I think of it this way: You check a checkbox and your iPad app magically runs on macOS, for free, meaning without extra effort on your part. The basic conversions are done for you. Now, in most cases, you can (and probably need to) make other changes to optimize the look and feel.

I'm not surprised that only a limited set of apps turn out perfectly suited for macOS after the automatic conversion, and Apple will make adjustments to Mac Catalyst so that it'll meet the hype for more and more types of apps. I guess that makes me an optimistic realist.

Wait... let me get this straight... a framework in its infancy is having issues? Developers are thinking something would be easier than it really is?

This framework is about going forward. This means when designing a new iPad app, you can be ready for making it work on Macs too. Obviously, back porting is always harder because those weren't considerations.

Very ambitious release this with all the changes.

Removing 32-bit App support.​
Replacing iTunes with dedicated Music and Video apps.​
Enabling Catalyst for third party developers.​
I think I'll give it a few months before updating, let things smooth out. I know they do public betas now but there's always things they don't get around to fixing before release.

Java was is and will continue to be garbage.
Agreed, it amazes me Steve Jobs didn't comment on it like he did with flash.

What exactly is wrong with the website? Why does everyone need everything to be an app? You're on a computer! Use the website!
Nothing wrong with the website, just contempt towards Mac Users, big companies can easily afford to develop a Mac App, why Windows only?

Apple says makes porting iPad apps to the Mac as easy as checking a box in Xcode.

Enough said
Except that is not what Apple ever said. They are very clear that to get a good Mac app still requires some work, specifically for the issues raised by the developers quoted. The real question is will this be a small amount of work making it worth doing for some developers, or a large amount of work, making it not worth it.

As for the quote that the future of macOS development is Catalyst, that’s just wrong. The future is SwiftUI. It makes creating UIs for each device easy, with core code running on all the different platforms.
