When I open the project file in the latest xcode version, I get the error "The folder "Images.xcassets" doesn't exist" in two popups. I have to click OK multiple times to make the popups disappear. I haven't done anything to remove such folders. Does anyone have an idea why I might be getting them?
I see it in finder and in my project explorer too. The problem still persists.
You have probably set your launch images to be extracted from an asset catalog (which is 'images.xcassets' by default). If you don't want to use asset catalogs, go to your application settings and select 'don't use asset catalogs', but, if you do (I recommend you do use asset catalogs for App Icons and Launch Images), click 'create asset catalog'. If that option isn't available, right click on your project, select 'New File', go to 'Resource', and select Asset Catalog.
