Map Sorting

[lovee (Elvis Shi)]

Great idea! I missed this topic but I think min(by:) max(by:) methods can also be applied, and I wrote about this idea here:

Sort(by:) min(by:) max(by:) with keyPaths

4 years ago there was a similar discussion: Now 4 years passed and now we've got the new KeyPath feature, but we still don't have a convenient method to sort a sequence, or get the max / min element by its elements' properties For example currently if we want to get the greatest element from a sequence according to a property of its elements, with the standard library the only way is to write a customized closure to compare 2 elements like this: let max = sequence.max(by: { $0.property < $1.…

From my perspective max and min needs this method even more than sort, because it's really unclear what { $0.age < $1.age } means to min or max.
