var dict: [String: Any?] = ["a": nil, "b": 0, "c": 1]

// 1. Map and comapctMap
// This works. Although the dictionary value is still optional even though it could never be nil here 👍
let mappedDict = dict.map { return $0.value != nil ? $0 : nil }.compactMap { $0 }
print(mappedDict)

// 2. Filter
// Filtering achieves the same
let filteredDict = dict.filter { $0.value != nil }
