var globalCountArray = [AnyObject]()
var assetDictionary = [String:AnyObject]()
globalCountArray.append(assetDictionary as AnyObject)
How to filter dictionary using Anyobject array? I have tried this.
globalCountArray = globalCountArray.filter {$0 as AnyObject != dict }
But I got error
Binary operator '!=' cannot be applied to operands of type 'AnyObject' and '[String : AnyObject]'"
Try using this
var globalCountArray = [AnyObject]()
var assetDictionary = [String:AnyObject]()
globalCountArray.append(assetDictionary as AnyObject)
let dict = [String:AnyObject]()
globalCountArray = globalCountArray.filter({ (obj) -> Bool in
if obj is[String:AnyObject] {
return (obj as! [String:AnyObject]) != dict
}
return false
})
--------- OR You can achieve the same via ----------
globalCountArray = globalCountArray.filter({ (obj) -> Bool in
if obj is[String:AnyObject] {
return (obj as! [String:AnyObject]) == dict
}
return true
})
You need to add this method to outside your class definition.
public func !=(lhs: [String: AnyObject], rhs: [String: AnyObject] ) -> Bool {
return !NSDictionary(dictionary: lhs).isEqual(to: rhs)
}
public func ==(lhs: [String: AnyObject], rhs: [String: AnyObject] ) -> Bool {
return NSDictionary(dictionary: lhs).isEqual(to: rhs)
}
You can write an extension for Dictionary:
extension Dictionary where Key: ExpressibleByStringLiteral, Value: AnyObject {
func isEqual(_ dictionary: [String: AnyObject]) -> Bool {
return NSDictionary(dictionary: dictionary).isEqual(to: self)
}
func isNotEqual(_ dictionary: [String: AnyObject]) -> Bool {
return !NSDictionary(dictionary: dictionary).isEqual(to: self)
}
}
Then you can compare [String: AnyObject] dictionaries with:
FirstDictionary.isEqual(SecondDictionary)
FirstDictionary.isNotEqual(SecondDictionary)
In your case:
var globalCountArray = [AnyObject]()
var assetDictionary = [String:AnyObject]()
globalCountArray.append(assetDictionary as AnyObject)
globalCountArray = globalCountArray.filter { (($0 as! [String: AnyObject]).isNotEqual(assetDictionary)) }
globalCountArray.filter {$0 as? [String: AnyObject] != dict }?
