SwiftyJSON & Swift 3: Cannot convert return expression of type 'Int32?' to return type > 'Int?'

Question

We are upgrading to SwiftyJSON Swift 3 with CocoaPods config pod 'SwiftyJSON', '3.1.0'.

We are getting this error:

/Users/xxx/Documents/iOS/xxx/Pods/SwiftyJSON/Source/SwiftyJSON.swift:866:33: Cannot convert return expression of type 'Int32?' to return type 'Int?'

Error is on the return statement in SwiftyJSON.swift:

public var int: Int? {
    get {
        return self.number?.int32Value
    }
    set {
        if let newValue = newValue {
            self.object = NSNumber(value: newValue)
        } else {
            self.object = NSNull()
        }
    }
}

Anyone know what the issue is? Is this an issue with our CocoaPods config or with SwiftyJSON?

Answer 1

I Just replace one line of code with below code. Simple

public var int: Int? {
        get {
            return self.number?.intValue
        }
        set {
            if let newValue = newValue {
                self.object = NSNumber(value: newValue)
            } else {
                self.object = NSNull()
            }
        }
    }

Realized the supported version of SwiftyJSON is 3.0.0 and not 3.1.0. Used 3.0.0 and the issue went away.

pod 'SwiftyJSON', '3.0.0'
