Generic fallback for Equatable in Swift 2.2

Question

I have a bug in Equatable at compile time. I wanted to add the find or contains method to the list to check the value. My code is below

class Generic: NSObject, Equatable, NSCoding //Am Having an error -  Redundant conformance of 'Generic' to protocol 'Equatable'

{

  var genericCode: String?
  var genericName : String?
  var genericType : String?
  var genericImageUrl : String?
  var genericPhone: String?
  var orgName : String?

override init()
{

    self.genericCode = String("")
    self.genericName = String("")
    self.genericType = String("")
    self.genericImageUrl = String("")
    self.genericPhone = String("")
    self.orgName = String("")

}

//Parameterzed Constructor for the Generic
init(genericCode: String , genericName: String , genericPhone: String, genericType: String, genericImageUrl : String)
{
    self.genericCode = genericCode
    self.genericName = genericName
    self.genericType = genericType
    self.genericImageUrl = genericImageUrl
    self.genericPhone = genericPhone

}

required init(coder aDecoder: NSCoder) {
    genericCode = aDecoder.decodeObjectForKey("genericCode") as? String
    genericName = aDecoder.decodeObjectForKey("genericName") as? String
    genericType = aDecoder.decodeObjectForKey("genericType") as? String
    genericPhone = aDecoder.decodeObjectForKey("genericPhone") as? String
}

func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(genericCode, forKey: "genericCode")
    aCoder.encodeObject(genericName, forKey: "genericName")
    aCoder.encodeObject(genericType, forKey: "genericType")
    aCoder.encodeObject(genericPhone, forKey: "genericPhone")
}

}

func ==(lhs: Generic, rhs: Generic) -> Bool
{
  return lhs.genericCode == rhs.genericCode
}

An error has occurred, is it because I use NSCoding and NSobject?

Answer 1

According to docs it NSObject corresponds to Equatable:

Complies with
CVarArgType
CustomDebugStringConvertible
CustomStringConvertible
Equatable
Hashable
NSObjectProtocol

... therefore, as your mistake says, Equatable matching is redundant ...

Answer 2

, NSObject, Equatable. Object: Equatable .

, (NSObject , ). Equatable NSObject, (: Equatable), :

static func ==(lhs: Object, rhs: Object) -> Bool {
   return lhs.text == rhs.text
}
