Swift Json Parsing Error

Yesterday, when developing the company's iOS program, I encountered a JSON parsing problem, and it was a very strange question.

Because the original code is more complex, so the code is a little simplified, the code is as follows:

Server return Format (PHP):

Array (' title ' = ' Sina ', ' address ' = ' http://www.sina.com.cn '), Array (' title ' = ' + ' NetEase ', ' address ' = ' h ') Ttp://www.163.com '));

The code for the parsing section is as follows:

var jsondata:anyobject! =  nsjsonserialization.jsonobjectwithdata (data,                                options:nsjsonreadingoptions.mutableleaves,error:nil); var links = [Link] (); If let Linksdata = Jsondata as? Nsarray {for    linkdata:anyobject! in Linksdata {       if let linkdict = LinkData as? nsdictionary {let             link = link ();             Link.title = linkdict["title"] as String;             Link.address = linkdict["Address"] as String             links.append (link);}}       

Originally this is a very simple parsing, and there is no problem when executing here, but the key is that the application will report a bad_access error access after execution is complete.

There are a number of methods behind it, several methods are tried later, there is no error in writing another method, and check the difference in this code:

For linkdata:anyobject! In Linksdata

No error code:

For LinkData in Linksdata

Specific reasons, because I am not very familiar with Swift, so it is not clear.

But the following will all: anyobject! removal, found that the program did not appear bad_access error.

Make a note of it and hope that everyone who meets this question will help.
