ios - Filtering Arrays Containing Multiple Data Types in Swift3 -

i have array like:-

var arraydata : array<dictionary<string, [bottlemodel]>> = [] 

bottle model :-

class bottlemodel: nsobject {      var name : string     var price : int     var reviews : int     var category : string     var quantity : string     var id : string     var shopdata : shopmodel } 

i want filtered array price > 2000

i tried let searchbyints = arraydata.filter({m in m.price < 200}) getting below error:

contextual closure type '(dictionary) -> bool' expects 1 argument, 0 used in closure body

how filter such kind of array based on price

working code:

let searchbyints = arraydata.filter { $0.values.contains { $0.contains { $0.price > 2000 } } } 

by way please write following using literals:

var arraydata : [[string : [bottlemodel]]] = [] 

still no idea if want because goal very unclear. have array of dictionaries of arrays contain values want filter out. if bottlemodel costs more 2000 want keep entire array contained in , dictionary array in? might want map entire data 1 flat array before or after filtering.

alternative using flatmap:

let flat = arraydata.flatmap { $0.values.flatmap { $0 } } let searchbyints2 = flat.filter { $0.price < 200 } // or other criteria
