ios - Swift3 version for emojilessStringWithSubstitution -


my current implementation has :

var emojilessstringwithsubstitution: string {     let emojipatterns = [unicodescalar(0x10000)...unicodescalar(0x10ffff), unicodescalar(0x2600)...unicodescalar(0x27ff)]     return self.unicodescalars         .filter { ucscalar in !(emojipatterns.contains{ $0 ~= ucscalar }) }         .reduce("") { $0 + string($1) } }

errors occur : 1. integer literals overflow when stored uint8 2. when store unicode scalar in variables , try assign error binary operator '...' cannot applied 2 'unicodescalar?' operands

kindly help.

modify code below,

    var emojilessstringwithsubstitution: string {     let emojipatterns = [0x10000...0x10ffff, 0x2600...0x27ff]     return self.unicodescalars         .filter { ucscalar in !(emojipatterns.contains{ $0 ~= int(ucscalar.value) }) }         .reduce("") { $0 + string($1) } }
