swift - How to convert a string that looks like an array's values to an array? -

i've string looks array shown below. how can transform string array shown below? i've tried this solution got error xcode(command failed due signal segmentation fault 11) , i've thought way hard compiler.

string:

var list = "<strong>up</strong>, <strong>up</strong>, <strong>down</strong>, <strong>up</strong>" 

target array:

var array = [<strong>up</strong>, <strong>up</strong>, <strong>down</strong>, <strong>up</strong>] 

and when tried let arr = list.characters.split {$0 == ","} prints:

[swift.string.characterview(_core: swift._stringcore(_baseaddress: 0x0000000103152e40, _countandflags: 9223372036854775811, _owner: nil)), swift.string.characterview(_core: swift._stringcore(_baseaddress: 0x0000000103152e48, _countandflags: 9223372036854775812, _owner: nil)), swift.string.characterview(_core: swift._stringcore(_baseaddress: 0x0000000103152e52, _countandflags: 9223372036854775817, _owner: nil)), swift.string.characterview(_core: swift._stringcore(_baseaddress: 0x0000000103152e66, _countandflags: 9223372036854775816, _owner: nil)), swift.string.characterview(_core: swift._stringcore(_baseaddress: 0x0000000103152e78, _countandflags: 9223372036854775815, _owner: nil))] 

with whitespace(let arr = list.characters.split {$0 == ", "}) gives compiler error:

• command failed due signal segmentation fault 11

would work:

var list = "<strong>up</strong>, <strong>up</strong>, <strong>down</strong>, <strong>up</strong>"  {     //create reggae , replace "," following spaces comma     let regex = try nsregularexpression(pattern: ", +", options: nsregularexpressionoptions.caseinsensitive)     list = regex.stringbyreplacingmatchesinstring(list, options: nsmatchingoptions.withoutanchoringbounds, range: nsmakerange(0, list.characters.count), withtemplate: ",")     var array = list.characters.split { $0 == ","}.map(string.init) } catch {     //bad regex created } 

edit: updated example remove componentsseparatedbystring native swift way. problem example resulting array did not contain strings seems internal class called characterview. mapping these strings produces desired output.

output:

[     "<strong>up</strong>",      "<strong>up</strong>",      "<strong>down</strong>",      "<strong>up</strong>" ]
