I am reading safari's Bookmarks.plist and storing it in an NSDictionary then trying to convert the NSDictionary into JSON
Problem
Bookmarks data is getting into dictionary but when I am converting the data into JSON the application is crashing.
NSString* path = #"path of the plist file";
NSDictionary *plistDict = [NSDictionary dictionaryWithContentsOfFile:path];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:plistDict
options:NSJSONWritingPrettyPrinted error:&error];
NSString* result = [[NSString alloc] initWithData:jsonData
encoding:NSUTF8StringEncoding];
Reason
The NSDictonary made of the Plist file contains some fields that are the type of NSData. Is there a way to convert all NSData fields to Base64 string in order clean the NSDictionary? Note that it is not possible to be aware of what fields and how many fields are type of NSData beforehand.

Before converting any object into json, first check that given object is json convertible or not, you can use following code to check that
if ([NSJSONSerialization isValidJSONObject: plistDict])
{
....
}
Because a JSON Object must be of type NSArray or a NSDictionary while you are passing a NSString.
From the docs :
An object that may be converted to JSON must have the following
properties:
The top level object is an NSArray or NSDictionary.
All objects are instances of NSString, NSNumber, NSArray, NSDictionary, or NSNull.
All dictionary keys are instances of NSString.
Numbers are not NaN or infinity.
Your data structure can be successfully read into a NSDictionary instance. But when you serialize it to JSON it fails because it contains parts that cannot be represented as JSON.
My guess is that it's the data at $.Sync.ServerData. This seems to be binary data. JSON doesn't have an data type for binary data.
Remove this element before you serialize it. Or replace it with something else, e.g. a string with a Base-64 representation of the binary data.
The crucial information is
Invalid type in JSON write (__NSCFData)
JSON does not support NSData type (the value of ServerData), you might send the data as string Base64 encoded.
This is the key:
Invalid type in JSON write (__NSCFData)
You cannot serialise NSData to JSON. Try encoding it to string using base-64 (see this answer to do that).
Do this way may be it helps you
{ NSURLResponse *response;
NSError *err;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *str=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];

self.handmadeEmbDict = [dict6 objectForKey:#"hemb_list"];
[handmadeEmbTable reloadData];
}

if (data == (id)[NSNull null]){

My view controller code is:
let appDelegado:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let contexto:NSManagedObjectContext = appDelegado.managedObjectContext
let entidadMarca = "Marca"
let entidadModelo = "Modelo"
let modeloNike = "AIRFORCE 1"
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//Conusltando Base de datos
let newMarca = NSEntityDescription.insertNewObjectForEntityForName(entidadMarca, inManagedObjectContext:contexto)
newMarca.setValue("NIKE", forKey: "nombre")
print("nueva marca ----->\(newMarca) \n")
//objeto modelo
let newModelo = NSEntityDescription.insertNewObjectForEntityForName(entidadModelo, inManagedObjectContext:contexto)
newModelo.setValue("AIRFORCE 1", forKey: "nombre")
let entytiModelo = NSEntityDescription.entityForName(entidadMarca, inManagedObjectContext:contexto)
let objArray = newMarca.mutableSetValueForKey("modelos")
objArray.addObject(newModelo)
print("Nuevo modelo:::::::: \(newModelo)")
print("arreglo \(objArray)")
saveInBD()
print("Nuevo Marca \(newMarca)")
let entityMarca = NSEntityDescription.entityForName(entidadMarca, inManagedObjectContext:contexto)
let oderBy = NSSortDescriptor(key: "nombre", ascending: true)
let consulta = NSFetchRequest(entityName:entidadMarca )
consulta.sortDescriptors = [oderBy]
let predicate = NSPredicate(format: "modelos = %#",modeloNike )
consulta.entity = entityMarca
consulta.predicate = predicate
if let resultado = try?contexto.executeRequest(consulta){
print("Resultado:::::::--->\(resultado)")
}else{
print("No hay Valores")
}

func saveInBD() {

try contexto.save() // Il metodo .save() dell'NSManagedObjectContext svolge questo compito.
} catch let error {

}
It looks like:
You are fetching the entity Marca
Your predicate for this fetch is NSPredicate(format: "modelos = %#",modeloNike)
modelos is a to-many relationship, which will be represented as a set
modeloNike is a String
So you're asking Core Data to compare two things which are not of the same type, comparing a set to a string. There's your problem.
I'm working on a iOs program in Swift, I'm using Core Data, I tried to found how to have a auto increment id, I found this:
But no issues here, so I tried to see how to write a self auto increment attribute:
I added a new attribute in my .xcdatamodeld file named "id", I found a solution in Objective-C:

Still confusing with the example you gave in the comment. My answer is based on my understand that you want an auto increase field - id, when next time you insert a new entry.
If you have two fields, i.e. xmlString & id. Then first you do everytime is a fetch request with SortDescriptor and setFetchLimit = 1. If the result is empty, you insert a new entry with id = 1. Otherwise, insert a new entry with id = oldId + 1.
I intentionally doesn't provide any code, because I'm not sure what you really want.
BTW, you'd better to use custom model, i.e. NSManagedObject generated by XCode, rather than the current newDemande.setValue(value, forKey: "key")
EDIT
Example code provided:
// Initialize Fetch Request
let fetchRequest = NSFetchRequest(entityName: "Demandes")
// Sort Descriptor
var idDescriptor: NSSortDescriptor = NSSortDescriptor(key: "id", ascending: false)
fetchRequest.sortDescriptors = [idDescriptor] // Note this is a array, you can put multiple sort conditions if you want
// Set limit
fetchRequest.fetchLimit = 1
var newId = 0; // Default to 0, so that you can check if do catch block went wrong later
do {
let results = try self.managedObjectContext.executeFetchRequest(fetchRequest)
//Compute the id
if(results.count == 1) newId = results[0].id + 1 // slightly odd notation here, .id can be used if you use custom model. or you can use .valueForKey("id")
else newId = 1
} catch {
let fetchError = error as NSError
print(fetchError)
}
// Do the new insert afterwards
I think you are sending a string value (781EFF10-A9F1-4710-98C1-6D342B2EB480) and core data is expecting an NSNumber (Int). Obviously, 781EFF10-A9F1-4710-98C1-6D342B2EB480 is not a number.
Core data always stores Int (Doubles, Float, etc...) values as NSNumber, for example:
let intValue
let intValueInNSNumber = NSNumber(int: intValue)
The difference is that intValue (Int) is a primitive type, while NSNumber is an object.
What's the type for the attribute "id"?
Because, if the attribute is of type "Int" you will have to change it to "String" and it should work.

I met a crash when i try to get the addresses for the give hostname;
the crash log shows like this:

BOOL isSuccess = CFHostStartInfoResolution(hostRef, kCFHostAddresses, nil);

[addresses addObject:[NSString stringWithCString:ipAddress encoding:NSASCIIStringEncoding]];
}
CFRelease(hostRef);

}
this function do called by several threads, and the doc of CFHostCreateWithName says that it is thread safe, now i have no idea about how to solve this problem.

Here the [lengthy] method code. I see a couple of places where I can add the check but how to I know it for sure that I fixed the issue? The problem is sporadical and I cannot reproduce it easily.

Short Answer:
You are sending a message to an object that cannot validly respond to it. The stack trace is telling you that when you make the call [PaymillPaymentService handleTransactionListRequest:] that PaymillPaymentService cannot accept handleTransactionListRequest.
Long answer:
Look at the stack trace here:
5 Control 0x10005acb4 -[PaymillPaymentService handleTransactionListRequest:] (PaymillPaymentService.m:211)
This is telling you that in the file PaymillPaymentService.m on line 211 you are sending PaymillPaymentService the message handleTransactionListRequest to which it cannot validly respond. In your discussion with rmaddy, Hot Licks, and Paulc11 you mentioned that line 211 is the function entry for handleTransactionListRequest (in whatever file it resides). If that's the case it is coincidental.
If you want further follow up you need to post PaymillPaymentService.m and ensure that you include all the line numbers.
When I try to build my project i get the following error on line 827
/PATH_TO_PROJECT/Libs/CocoaLibSpotify/Model/SPPlaylist.m:827:25: Implicit conversion of Objective-C pointer type 'AVAssetTrack *' to C pointer type 'sp_track *' (aka 'struct sp_track *') requires a bridged cast
Here is the code where the error occurs:

834
835 if (block)

837
838 sp_error errorCode = sp_playlist_add_tracks(self.playlist, trackPointer, (int)newItems.count, (int)index, self.session.session);
839 free(tracks);
840 tracks = NULL;
841
842 NSError *error = nil;
843 if (errorCode != SP_ERROR_OK)
844 error = [NSError spotifyErrorWithCode:errorCode];
845
846 if (error && block) {
847 [self.addCallbackStack removeObject:block];
848 dispatch_async(dispatch_get_main_queue(), ^{ block(error); });
849 }
850 });
851 }
Thanks for your help!
The error is pretty self-explanatory - you need to make a bridged cast.
track = (__bridge sp_track *)[item track];
or
track = [(SPPlaylistItem *)item track];
