Question

在RealmSwift 3.21.0中，我在name: "services"和child = { value: 0x0, label: "services" }的Realm的Object.swift文件中遇到此崩溃：

private static func getOptionalPropertyMetadata(
        for child: Mirror.Child,
        at index: Int
    ) -> RLMSwiftPropertyMetadata? {
        guard let name = child.label else {
            return nil
        }
>>>     let mirror = Mirror(reflecting: child.value) //Thread 13: EXC_BAD_ACCESS (code=1, address=0x0)
        let type = mirror.subjectType
        let code: PropertyType

对于此模型：

class RealmAppointment: Object, Codable {
    override static func primaryKey() -> String {
        return CodingKeys.id.stringValue
    }

    @objc dynamic var id: String
    @objc dynamic var startAt: Date
    @objc dynamic var createdAt: Date! = Date()
    @objc dynamic var updatedAt: Date! = Date()
    let services = List<String>() // var also doesn't work
}

奇怪的是，我在另一个Realm对象上以相同的方式定义了服务，并且它的工作原理是：

public class RealmOffer: Object, Codable {
    override public static func primaryKey() -> String {
        return CodingKeys.id.stringValue
    }

    static let updatedAtKey = CodingKeys.updatedAt.stringValue

    @objc dynamic public var id: String?
    @objc dynamic public var startAt: Date! = Date()
    @objc dynamic public var createdAt: Date! = Date()
    @objc dynamic public var updatedAt: Date! = Date()
    public var services = List<String>()
}

有什么想法吗？

很奇怪，更改了RealmAppointment.services的定义，

let services = List<String>()

到

let services: List<String>! = List<String>()

修复了此崩溃。
