Error in adding an element to [String:Array] in Swift

ios,arrays,swift,nsdictionary

The problem is probably that you are unwrapping self.model.data[i] when you assign [dict] to it. I assume you are doing that in the case where data[i] has no value yet. So the forced unwrap will result in a nil pointer, which causes a crash. Try this: for var k=0;k<body.count;k++ {...

Need to reload/recalculate NSArray

ios,arrays,database,nsdictionary

You should not store the Opening State. This should be a computed property. Create method that returns this value when requested: - (OpeningState)openingState { OpeningState _openingState; NSDate *openingTimeDate = [timeFormat dateFromString:[currentDay stringByAppendingString:_openingTime]]; NSDate *closingTimeDate = [timeFormat dateFromString:[currentDay stringByAppendingString:_closingTime]]; // Find out opening state of the restaurant if(([openingTimeDate compare:now] == NSOrderedAscending)...

Content of a NSMutableDictionnary erratically returned

cocoa,nsdictionary,nsmutabledictionary

This is a guess: The information supplied does not show that your type myKey implements isEqual: and hash. Keys must implement these methods to work correctly in an NSDictionary; if they are not implemented the default NSObject implementations will be used and they probably do not produce the correct results...

EXC_BAD_ACCESS with NSDictionary/CFDictionaryRef

objective-c,nsdictionary,exc-bad-access

It looks like bad memory management. You call CFRelease on batProps after bridging the pointer to an NSDictionary. This leaves batteryRawDict pointing to garbage.

In your edit it looks like you're using SwiftyJSON. If that is indeed the case, you can help the compiler to know what's in the dictionary by using SwiftyJSON's dictionaryValue property: let jParams = jdata["responseData"]["extraData"]["params"].dictionaryValue Then you should be able to access your values without downcasting: let title = jParams["title"]...

Searching an Array of Strings in Array of Dictionaries

It might be helpful to use (NSPredicate*)predicateWithBlock: method to speed up searching. Suppose you have a keys array and a source array, you want to filter the source array with the keys array.

NSPredicate filtering an array based on a localised string entry

I think your problem is in the %K.%@, if you look at the final predicate I believe that it will put quotes around the %@, which is not what you want (guessing by the dot notation).

Why my NSDictionary that was from json sorted like this?

ios,json,swift,sorting,nsdictionary

Obj-C setValuesForKeysWithDictionary 64-bit vs 32-bit

ios,objective-c,json,nsdictionary,32bit-64bit

NSDictionary objects are unordered collections, so code should never make assumptions about the order in which a dictionary will enumerate its own keys. It turns out that there are implementation differences between the 32- and 64-bit runtimes that affect where hashed values end up being stored. Since the API contract...
