What’s Coming Up Next? – Tom Bluewater Introducing justIcons 3 for Mac OS X

Mac application justIcons 3

TOKYO (MacHouse) – This month is almost over. Hmm… I still have time for one more desktop application. In fact, I submitted a new software title to Mac App Store several minutes ago. This new software submission is called justIcons 3.

The justIcons series is now more than four years old. It’s been developed from a scratch in Swift. justIcons 3 supports both Xcode 8 and Xcode 9.

justIcons 3 makes software development easier by letting you create an icon set (AppIcon.appiconset) out of a single image file for Xcode. Imagine that you have to create more than a dozen images if you develop a Universal iOS app. With justIcons 3, it’ll take a single image to create the entire icon set folder containing the JSON folder (Contents.json).  

What’s new?

  1. The application supports both Xcode 8 and Xcode 9
  2. justIcons 3 now creates the AppIcon.appiconset folder not just for macOS but also for iOS and watchOS.


  1. Drag and drop source files directly onto the list box.
  2. The user can create an icon set (AppIcon.appiconset) for all three development platforms (macOS, iOS, watchOS) at a time.
  3. Create an icon set folder compatible with Xcode 8 and Xcode 9.
  4. Choose iPhone only, iPad only or Universal for an iOS app.
  5. Create an icon file (.icns) for macOS. (See Preferences.)
  6. In compliance with Xcode 9, the user has options of removing or not removing the alpha channel for iOS icon images. (v. 3.0.2)
  7. The fullScreen mode is supported.
  8. The application supports the retina screen. (tested with 2014 2.6 GHz 13″ MacBook Pro)
  9. Languages: English only.
  10. Application file size: 22.7 MB.
  11. The application comes with a built-in 10-page user guide. Click on the Quick tour toolbar button or choose Show Quick Tour under justIcons 3 whenever you need to see it.

System requirements

  1. 10.11 (tested with 10.11.6), 10.12 (tested with 10.12.2 and 10.12.5), 10.13 (tested with 10.13 beta Build 17A362a)
  2. 64-bit system


  1. The application is free for use in creating an icon set for watchOS. Creating an icon set for macOS and iOS requires a separate in-app purchase.
  2. A source image must have a 1-to-1 aspect ratio (width = height).

Version history

Version 3.0.2 (Released on January 4th, 2018)

  1. In creating iOS icons for Xcode 9, the user now has options of removing or not removing the alpha channel from icon images. Please see the general settings tab of Preferences.
  2. Some changes are made to the database files that this application uses due to transition to Swift 4.

    Program is not working on MacOs 13.13.3 make icon is blank

  2. If you want to report a problem, please read Question? at the top and provide more information. By your saying “make icon,” I don’t know what type of icon you have tried to create.

  3. Tomi Ahopelto says:

    Make icon button in program is not working(blank greyed)
    cant create any icons

  4. Please send one or more screenshots to junk913@gmail.com.

  5. Tomi Ahopelto says:

    sorry my fault program works good just user who was not pictures have to be 1024 if you want make 512

  6. If the make icons toolbar button is disabled, chances are that you don’t have images in right sizes listed. If you read Quick Tour Page #2 and #3, it tells you that images must have the square ratio and that the app will tell you of the required size if you just place your mouse pointer over any of the three checkbox buttons.
