Assets is a macOS app that manages assets for your developement projects (Xcode, web, etc)
1/ Choose a project root folder. Assets will browse it and collect all assets
2/ Place Designer assets by either choosing a root folder or drag and dropping images.
3/ Click on Publish to replace all projects assets with the designer's assets.
4/ Save the file and reuse when new assets available.
1/ Open your saved assets file.
2/ If your new assets are in the same path as before and have the same names, simply click publish.
3/ If your new assets are in a different folder but have the same names, choose the new root Designer folder and then click publish.
4/ If your new assets are in a different folder and have different names, go back to first run.
