    I'm new to Fiverr and needed help with my existing iOS Application as I had a tight schedule. Sergey made a custom offer and we agreed on 2 tasks: - Adopt dark mode in CTAssetsPickerController - And make it Carthage compatible. He did the first task flawlessly but couldn't complete the second one....
