Problem in creating relationship one-to-one

[mrfer]

Good day!

I have two classes:

import SwiftyJSON
import Realm
import RealmSwift

class OfficeModel: Object {
    
    var id = RealmOptional<Int>()
    @objc dynamic var city: String?
    @objc dynamic var address: String?
    @objc dynamic var phone: String?

    @objc dynamic var coordinate: OfficeСoordinates?
    
    convenience init(json: JSON) {
        self.init()
        self.id.value = json["Id"].int
        self.city = json["City"].string
        self.address = json["Address"].string
        self.coordinate = OfficeСoordinates(json: json["Coordinates"])
    }
    
}

class OfficeСoordinates: Object {
    
    var latitude = RealmOptional<Double>()
    var longitude = RealmOptional<Double>()
    
    convenience init(json: JSON) {
        self.init()
        
        self.latitude.value = json["Latitude"].double
        self.longitude.value = json["Longitude"].double
    }
}

The first time you access realm, the following error occurs:

Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=io.realm Code=1 "Schema validation failed due to the following errors:

• Property 'OfficeModel.coordinate' of type 'object' has unknown object type 'OfficeСoordinates'" UserInfo={NSLocalizedDescription=Schema validation failed due to the following errors:

Declared the property @objc dynamic var coordinate: OfficeСoordinates? as indicated on this page: https://realm.io/docs/swift/latest/#using-the-realm-framework

Tell me, please, what is the error here?

Realm framework version: 3.0.2

Realm Object Server version: n/a

Xcode version: 9.1

iOS/OSX version: iOS11

Dependency manager + version: Cocoapods 1.3.1

The underlying cause here is your use of Unicode codepoint 0421, CYRILLIC CAPITAL LETTER ES, in place of the uppercase C in the type name of OfficeСoordinates. Replacing that with a normal Latin C fixes the problem.

@bdash Thank you very much, it helped!
