The status of 32-bit and 64-bit macOS apps

The status of 32-bit and 64-bit macOS apps

Published July 11, 2018 by Paul Lefebvre

In the Mac world, 32-bit apps have been disappearing more and more as time goes on. This year already we’ve seen significant steps toward 64-bit.

In January 2018 Apple stopped accepting 32-bit app submissions to the Mac App Store.

In February 2018, starting with macOS 10.13.4, Apple added a warning that displays the first time you launch a 32-bit app.

In June 2018 Apple stopped accepting updates to 32-bit apps in the Mac App Store. All new apps and app updates must now be 64-bit.

At WWDC 2018 Apple announced that macOS 10.14 will be the final version that support 32-bit apps. Although they did not announce a release date, based on the timing from the past few years macOS 10.14 will probably be released around the end of September 2018.

Center a Window Using a macOS Declare

Published April 30, 2018 by Paul Lefebvre

You can call into Cocoa APIs to use methods and properties that are not built into the Xojo framework by using the Declare command. To create a Declare statement you first need to track down the API you want to use using Apple’s documentation: Apple Developer Documentation.

Do you need an iMac Pro for Development?

Do you need an iMac Pro for Development?

Published January 10, 2018 by Paul Lefebvre

Of course you want an iMac Pro! But do you really need one for your development work? Most of the iMac Pro videos and reviews seem to focus on video and audio editing, which are certainly tasks that make use of the many cores that are available (8-18).

But software development is also a Pro task. What benefits does an iMac Pro bring to a software developer?

Typically most people will opt for a computer that probably has four cores such as found in the i5 and i7 series. These are used in the popular Macbook Pro and iMac models, for example. Four cores sure sounds like a lot so why would a developer need more?

What it means for your Xojo projects if Mac goes ARM

Published September 29, 2017 by Geoff Perlman

I’ve speculated for some time now that Apple might decide to start putting their own ARM-based processors in Mac desktop and laptop computers. Apparently, I’m not alone in thinking this. It makes a lot of sense. Apple’s big advantage is being in control of all of the important aspects of their product lines and the processor is both figuratively and physically at the center of their products.

Clear the iTunes Apple Music Cache on macOS and Windows

Published July 12, 2017 by Paul Lefebvre

I love listening to music and have been a happy Apple Music subscriber since it was first released in 2015. Having access to 30 million songs is great even if I mostly just listen to the ones in the “Hard Rock” category (current favorite song: You Don’t Know by Kobra and the Lotus). Unlike some other streaming services, when you listen to a song with iTunes that has not been downloaded to your computer, it does not technically stream it while it’s playing. Instead iTunes downloads the full song to a cache folder and plays it locally from there. This has the advantage of there being fewer stutters as the song is playing, but does mean it takes a moment before the song starts playing the first time. Subsequent plays of the same song are instant, though, since it doesn’t have to download it again which may also save you some Internet data usage. A notable downside to this design is that it also means that these songs are using up space on your drive and with today’s smaller SSDs often every bit of space counts. It doesn’t appear that this space is ever cleared by iTunes, either.

These songs files are saved in a cache folder buried in hidden folders on macOS and Windows, which you can get to manually if you are comfortable with the command line.

Alternatively, you can easily make a quick Xojo app to do it for you.

Thoughts On WWDC 2017

Published June 5, 2017 by Geoff Perlman

This morning Tim Cook offered Apple’s keynote for WWDC 2017, where he focused on the new technology that is coming from Apple for developers, though there was not much on the API specifics. Over the last few years we’ve expanded our support for macOS by adding new platform features and we will continue to add new features to Xojo iOS. We’ll be looking at Apple’s product direction for new ways to advance Xojo and expand your ability to build cross-platform apps quickly and simply with Xojo.

JSON Feed Desktop App

Published June 1, 2017 by Paul Lefebvre

Recently, a new syndication format was introduced by Brent Simmons and Manton Reece called JSON Feed. It is an alternative to RSS/Atom to get feeds for blog posts and podcasts. RSS/Atom are XML-based making them complex to work with. As its name implies JSON Feed uses JSON and is much simpler. I’ve shown in previous posts how easy it is to make a web and iOS apps with Xojo to display the feed.

In this post, I’ll show you how to create a Xojo desktop app to display the JSON feed for Daring Fireball in less than 20 lines of code. This app works without changes on macOS, Windows and Linux.

Making a Mac App: Comparing Xojo and Visual Studio for Mac

Published May 18, 2017 by Paul Lefebvre

At the recent Build conference, Microsoft released the final version of Visual Studio for Mac. As a former Visual Studio developer who left that world for the fun, fast development that is Xojo, I had to check it out to see how it compares to Xojo.

First, if you’ve ever used Visual Studio on Windows before, be aware that Visual Studio for Mac is not the same thing. Essentially Visual Studio for Mac is new branding for Xamarin Studio (Microsoft bought Xamarin in 2016), so Visual Studio for Mac looks and works nothing like Visual Studio for Windows.

Creating Wrapper Apps With Xojo

Published January 17, 2017 by Javier Menendez

You already know, you can use Xojo to create practically any kind of application; from apps used by corporations, Universities and even Government agencies around the world, to apps used by photographers, designers and, of course, developers; and even those small utilities that makes our lives a bit easier.

In fact, a lot of these little utilities are what are known as Wrappers. That is, a nice user interface that simplifies and makes more user friendly a feature that is already available in the native operating system; often, in the form of one or more combined commands that need to be typed from the Command Line prompt.

You can watch the video (in Spanish, with English subtitles) as you read and work through this example.

Is Microsoft bringing Visual Studio to the Mac?

Published November 14, 2016 by Geoff Perlman

It is likely that later this week, Microsoft will be announcing Visual Studio for Mac. Is this really true? Why would they do this? What does it mean for Xojo users?
