![]() Boring! We want automation! Fix the automation So – of course one solution is to resolve this manually, by dragging files one by one into their correct wells. But maybe a more pertinent question is… What to do about this? Fix it manually My guess is this is a bug in Xcode, if anyone has more info on this feel free to add a comment here. Only some wells fill, others stay blank, and some files are treated as unassigned: However, as we saw, when you drag these icons into your app icon: Once you’ve set up your icon, you can specify File > Generate > Image Assets:Īnd this will output all the files you’ll need to create an app icon: Generating App Icon filesįirst, how to set up all of these versions of the app icon?Įasy! Apple provides a Photoshop (or Sketch or Adobe XD) template in the resources section of HIG for setting up an icon, that looks something like: There is some automation there, but weirdly it’s a bit hit and miss. So you’d think it would be just as easy to set up an app icon in the asset catalog. You just need to give each the three scale factor image files the correct syntax, something like:ĭrag them in and Xcode automatically detects the correct well for each image, and tada! Now you can go Product > Archive and, assuming you’re code signing is properly set up, you should be able to Validate app successfully.When you create an image set in Xcode, it’s so easy to automatically fill the wells for each scale factor. This generates the necessary files both for running and for archive. While you’re there confirm that the left pane now says Run (Release) and Archive (Release).(I uncheck Debug executable too but I don’t know if this matters.) Change Build Configuration to Release.Select MyApp target (top left item of main white panel, even though it doesn’t look selectable).Step 5: Create a release build before you archive (if using CMake Scheme > Edit Scheme… You should now find that if you build and run the app on a device, the app icon is present. This is what tells Xcode the name of your app icon within the asset catalog you’ve already identified in the ist. Under App Icons and Launch Screen, set App Icon to AppIcon.It’ll have a generic app icon to its left. In the main panel, select your MyApp target.Now you have to do a manual step in Xcode that unfortunately CMake can’t do AFAIK: You should see Icon files (iOS 5) > Primary icon > Icon files > Item 0: MyAppIcons Click this and you’ll see the contents of your generated ist. In your folder structure you’ll see Root folder > MyApp > Resources > Info.Click this and you’ll see the AppIcon icon set. In your folder structure you’ll see Root folder > MyApp > Resources > MyAppIcons.Run CMake to generate the Xcode project and open that in Xcode. MACOSX_PACKAGE_LOCATION Resources/MyAppIcons.xcassets/AppIcon.appiconset MACOSX_BUNDLE_BUNDLE_VERSION $ PROPERTIES |- both examples use the following CMake code set_target_properties(MyApp PROPERTIES In both cases, I have the following file structure for the app icons: project-root However I am struggling to get app icons into Xcode 14.2 in a form that it will accept. I am now ready to release a new version using Qt 6 + CMake. I have previously published my Qt app using Qt 5 + qmake.
