Hi, what would be the function to achieve the same result as the one obtained with flatMap
? i.e.: flattening an array of arrays to an array ?

iOS Development Techdegree Student 5,461 PointsIn Swift there were a few use-cases for using flatMap. Removing nil-values from an array. And flattening an array of arrays for example.
Removing nil-values with flatMap is being deprecated. Instead you can use .compactMap
for that. You can still use flatMap
to flatten an array of arrays.
