swift - For...in is giving "SourceKitService Terminated" -

every time typed "for x in variable" (trying iterate on textfield) error "sourcekitservice terminated"

does know if known issue? there fix? thanks!

edit:

code:

for token in expressiontextfield.text {     pf.expression += token  }

make sure expressiontextfield.text non-nil before iterating through it.

if let str = expressiontextfield.text{     token in str{         pf.expression += token     } }

that being said, bug xcode's parser should fixed fall.
