Groot cannot parse - Githubissues

for a very easy code:

    let data: JSONDictionary = [
        "enrollment_capacity": 10,
        "enrollment_total": 5,
        "section": "sec1"
        ]

    do {
        let eg: UWFetchedData = try object(withEntityName: "UWFetchedData", fromJSONDictionary: data, inContext: self.context) as! UWFetchedData

        print( "\(eg.section) \(eg.enrollment_capacity) / \(eg.enrollment_total)" )

    } catch {}

it prints "nil 0 / 0"

UWFetchedData are shown as this: the first two fields are integer, the last one is string

During the time it parse JSONDictionary, it prints error:
