Add new no-Optional property cause crash.

[yeseni-today]

// before
class A: Object {
    @objc dynamic var id: String = UUID().uuidString
}
// after
class A: Object {
    @objc dynamic var id: String = UUID().uuidString
    @objc dynamic var updatedAt: Date = Date()
}

Two Device. iPhone and iPad
using iPhone nothing error. and upload some record to cloudKit.
using iPad error. I get a crash. A.updatedAt.setter error.

I think updatedAt value in CloudKit is nil

// CKRecordRecoverable.swift parseFromRecord
recordValue = record.value(forKey: prop.name) as? Date // updatedAt is nil
o.setValue(recordValue, forKey: prop.name) // prop is no-optional. setter will get a error

so I try blow code and no error.

     if recordValue != nil || (recordValue == nil && prop.isOptional) {
                o.setValue(recordValue, forKey: prop.name)
            }

Hi @aollio , you were doing good job. This is indeed a bug in IceCream. I'll recheck later and merge this. Thank you!
