Cannot apply Mappable Protocol to NSManagedObject Subclass

[ReaddyEddy]

I'm seeing a very obscure build error with objects inheriting from NSManaged object, the code below is extracted form a sample project based on the MasterDetail template. ObjectMapper is installed via 0.36.0.beta.2 Cocoapods with the _Event and Event classes generated with mogenerator 1.28 --v2 --swift. It makes no difference whether the protocol is applied to the derived Human readable class or the Machine Readable class inherited form NSManagedObject.
This builds OK:
import Foundation
import ObjectMapper
class Lump: Mappable {
var timeStamp : NSDate?
required init() {}
func mapping(map : Map) {
timeStamp <= (map["timeStamp"],DateTransform())
}
}

This does not:

import ObjectMapper
@objc(Event)
class Event: _Event, Mappable {
func mapping(map : Map) {
timeStamp <= (map["timeStamp"],DateTransform())
}
}

The error message is
CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler
.. snip ..
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

Hi there,
Unfortunately I'm not sure what is going on here. I haven't tried using ObjectMapper with any classes that are visible to Objective-C code.

One thing I do notice in the above code is that the Event class doesn't include the initializer. Hope this helps..

Hi
The initialiser is provided by the base class. I suspect myself that the problem is one of using Cocoapods with the frameworks option but I'm yet to confirm that.
Thanks for the speedy response

Any news with that issue?

Thanks

Seems as though not using CocoaPods suse_frameworks directive allows a build I’ve yet to exercise the mapper though

I have been easily able to use ObjectMapper with Core Data. #195 for details.
