Swift – Cast Int64 to AnyObject for NSMutableArray

2 Solutions Collect From Internet About “Swift – Cast Int64 to AnyObject for NSMutableArray”

You are using a Foundation array (NSMutableArray), so you should use a Foundation number object:

ma.addObject(NSNumber(longLong:number))

You could also use a native swift array:

var ma = [Int64]()
ma.append(number)

Like so much of Swift, this is implemented in Swift.

So you can do this (or the equivalent for the types you want) which will magically make it possible to use an Int64 where the language expects an AnyObject:

extension Int64 : _ObjectiveCBridgeable
{
    public init(_ number: NSNumber)
    {
        self.init(number.longLongValue)
    }

    public func _bridgeToObjectiveC() -> NSNumber
    {
        return NSNumber(longLong: self)
    }

    public static func _getObjectiveCType() -> Any.Type
    {
        return NSNumber.self
    }

    public static func _isBridgedToObjectiveC() -> Bool
    {
        return true
    }

    public static func _forceBridgeFromObjectiveC(source: NSNumber, inout result: Int64?)
    {
        result = source.longLongValue
    }

    public static func _conditionallyBridgeFromObjectiveC(source: NSNumber, inout result: Int64?) -> Bool
    {
        result = source.longLongValue
        return true
    }
}
