How do I handle runtime error in swift? -

i not know how handle runtime error in swift. need check parsing error , it. can me please?

i have code this:

var:someobject = parse("some string") 

i need handle generic error occurs in runtime. thanks!

if function yours, in case of failure, can make function return nil value.

that way line of code

var anobj:someobject = parse("some string") 

would become this

var:someobject? = parse("some string") 

notice ? sign. means value in optional. in simple words, actual value, or nil. after function, should perform check like

if anobj != nil { //do } else { //the parse didn't go right, handle erorr here. }
