GenIcon makes it easy to produce icon assets for iOS, macOS, and watchOS.
Simply drag and drop your 1024x1024 icon into the drop zone, select the platform you're building for, and click generate icons.
This app does not create a .json file - you must drag and drop each image into it's dedicated slot within Xcode Assets. The Contents.json will generate, and the image files will populate in your project folder automatically.
Features:
• Resizes your 1024x1024 icon into every size necessary for iOS, macOS, and watchOS.
• Removes Alpha Channel/transparency for iOS/watchOS icons.
• Preserves Alpha Channel/transparency for macOS icons.
