ios - '_ ??' is not convertible to '()' with NSMutableAttributedString -


i've i'm pretty new swift , i'm stuck in setting nsmutableattributedstring in uilabel.

var attributedstring = nsmutableattributedstring("random string example") attributedstring.addattribute(nsforegroundcolorattributename, value: uicolor.redcolor(), range: nsmakerange(1, 3)) tweettextlabel?.text = attributedstring

the last line gives me: '_ ??' not convertible '()' can't compile.

i tried with: 

tweettextlabel?.text = attributedstring.string

but in way lose color attribute

you should set attributedtext property of uilabel, like:

tweettextlabel?.attributedtext = attributedstring
