Any help would be greatly appreciated, I found a post where someone had a similar issue and a solution was found, however, I'm still running into a wall:
Invalid Binary File after uploading on ITunesConnect
The exact error I get is the same, i.e. "Your package contains a file 'App Name.app/Icon ' with a name that contains invalid characters. Avoid using control characters in the file names." at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage)
I'm almost 100% certain all I need to do is find the offending file named "Icon .png" (the space before the .png is what messes everything up, I'm assuming) but I can't seem to find it. In the above post, looking into hidden files and folders was suggested but I'm not sure how to go about this as I've never done it before.
Any help would be much appreciated, thanks!
