How do you find a maximum value in a Swift dictionary?

Question

So, say I have a dictionary that looks like this:

var data : [Float:Float] = [0:0,1:1,2:1.414,3:2.732,4:2,5:5.236,6:3.469,7:2.693,8:5.828,9:3.201]
         


        

Answer 1

let maximum = data.reduce(0.0) { max($0, $1.1) }

Just a quick way using reduce.

or:

data.values.max()

Output:

print(maximum) // 5.828
