if any one develop with ios 7 and know how to solve this problem then help .
.....
if alert.alertViewStyle = UIAlertViewStyleSecureTextInput;
my xcode Version 5.0 (5A11386k)
is not working with ios 7 then we use old strategy like we do for ios 5 ?
thanks .
The problem is on your HomeViewController. You have a
[__NSArrayM objectAtIndex:]: index 2 beyond bounds [0 .. 1]
This means you are trying to access an index that doesn't exists, I think on line 246

I am calling this code on a background thread.
backgroundContext.performAndWait {
let fetchRequest:NSFetchRequest<BlogPost> = BlogPost.fetchRequest()
fetchRequest.predicate = NSPredicate.init(format: "postid=%#", argumentArray: [someInt64Value]) // this line creates an exception
_ = try? fetchRequest.execute()
....
}
If I remove the predicate, it works fine. The same predicate works just fine if used inside a fetchResultController. postid is Int64 but if I changed the predicate to any other key it would give the same NSInvalidArgumentException

I found the issue. Passing an Int64 confuses the argumentArray, casting it to Int fixes the issue.
This seems to be a bug in NSPredicate() filed as radar 28749194
let id:Int64 = 5785905063264256 // Making this Int works
#objc class Test:NSObject {
let postid = id
}
let predicate = NSPredicate(format: "postid == %#"
, argumentArray: [id])
let mytest = Test()
predicate.evaluate(with: mytest) //false but should be true
In CoreData I want to fetch an element by a key. However executing the fetch request results in unrecognized selector sent to instance. The excerpt from my code is shown below, which fails on the last line. managedObjectContext is a valid instance, as I'm also that one to insert new instances. Could this be some incompatibility be with Swift's Int64 and CoreData's Integer 64?
var error : NSError?
var request = NSFetchRequest(entityName: "Node")
var nodeId = NSNumber(longLong: Int64(46763376))
request.predicate = NSPredicate(format: "id = %#", [nodeId])
var nodes = managedObjectContext.executeFetchRequest(request, error: &error)
Entity definition in the datamodel:
Node entity is defined in Swift as:
class Node : NSManagedObject {
#NSManaged var id: NSNumber
#NSManaged var lat: NSNumber
#NSManaged var lon: NSNumber
#NSManaged var tags: NSMutableSet
#NSManaged var ways: NSMutableSet
func description() -> String {
return "Node(id=\(id), lat=\(lat), lon=\(lon))"
}
}

The error is here:
request.predicate = NSPredicate(format: "id = %#", [nodeId])
because you pass an array to the "variable argument list" form of predicateWithFormat.
Both of these versions should work:
request.predicate = NSPredicate(format: "id = %#", nodeId)
request.predicate = NSPredicate(format: "id = %#", argumentArray: [nodeId])
Remark: The NSManagedObject documentation states that you are "strongly discouraged"
from overriding the description method in your subclasses.
My real code is full of NSLog's,
the following line is the reason for he crash but I don't understand why
NSString *newDir = [documentsDirectory
stringByAppendingPathComponent:file];
Here is the whole method:
- (void)viewDidLoad {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray* newArray= [[NSArray alloc]init];
newArray= [fileManager contentsOfDirectoryAtURL:[NSURL fileURLWithPath:#"/Users/admin/Library/FotoAppFotos/"]
includingPropertiesForKeys:[NSArray arrayWithObject:NSURLNameKey] options:NSDirectoryEnumerationSkipsHiddenFiles error:nil];
categories= [NSMutableArray arrayWithArray: newArray];
for(NSString *file in categories) {
NSString *newDir = [documentsDirectory stringByAppendingPathComponent:file]; // in this line the app crashes
[categories addObject:newDir]; //categories
}
[super viewDidLoad];
}
As mentioned the NSLog print of documentsDirectory and file are:
documentsDirectory: /Users/admin/Library/Application Support/iPhone
Simulator/4.3/Applications/D5AB6F90-0420-4A66-B141-D27AB2C11C3C/Documents
file://localhost/Users/admin/Library/FotoAppFotos/Audio/
The whole crash log is:

terminate called after throwing an instance of 'NSException'
Thank you for any help and presumption in advance
The hint comes from:
[NSURL length]: unrecognized selector sent to instance
If you are working on iOS, sorry to tell that :
This method is unimplemented in iOS, so it performs no operation.
Somebody has similar problem .
