I am trying to sort an Array used to populate a TableView.
My data is structured as following :
var data = [[Double:String]]()
ex : [[1450051409873: "foo"], [1450051409874: "bar"], [1450051409875: "baz"]]
I want my data to be sorted by the value of the doubles (i.e. 1450051409873...)
I am doing the following to sort my data:
data.sortInPlace({$0[0] > $1[0]})
This does not appear to work.
That's a dictionary, not an array. If you'd like to access the values sorted by the keys, you can create a sorted array of the keys, then access the values one at a time:
var data: [Double:String] = [1450051409873: "foo", 1450051409874: "bar", 1450051409875: "baz"]
var sortedKeys = data.keys.sort()
for key in sortedKeys {
print(data[key]!)
}
// foo
// bar
// baz
Or you can directly compute the sorted values by providing a closure to sort:
var sortedValues = data.sort({ lhs, rhs in
lhs.0 < rhs.0
}).map({ $0.1 })
// sortedValues == ["foo", "bar", "baz"]
