Realm program crashes while opening realm database #32

Closed lingolab2 closed 4 years ago

lingolab2 commented 4 years ago

program crashes when trying to open realm database.

        let config = Realm.Configuration(fileURL: destinationURL,
                                         readOnly: false,
                                         schemaVersion: 1,
                                         migrationBlock: { (migration, oldSchemaVersion) in
                                            if (oldSchemaVersion < 1) {

                                            }
        })
        let realm: Realm = {
            return try! Realm(configuration: config)
        }()

The debugger gives me a hint that it is in the object table Kanji and near column `kunYomis`

struct Kanji: Realmable {
  var id: Int = 0
  var kanjiCharacter: String = ""
  var hexUnicode: String = ""
  var frequency: Int = 0
  var jlptLevel: Int = 0
  var gradeJA: Int = 0
  var strokeCount:Int = 0
  var classification: String = ""
  var kunYomis = [String]()
  var onYomis = [String]()
  var longMeanings = [String]()
  var shortMeanings = [String]()
  var radicalComponentCount: Int = 0
  var radicalComponentStrings = [String]()
  static func primaryKey() -> String?
  {
    return "id"
  }

}

This is the definition of the database as shown by RealmStudio when generating Swift model definition

class RLMKanji: Object {
    @objc dynamic var id: Int = 0
    @objc dynamic var kanjiCharacter: String = ""
    @objc dynamic var hexUnicode: String = ""
    @objc dynamic var frequency: Int = 0
    @objc dynamic var jlptLevel: Int = 0
    @objc dynamic var gradeJA: Int = 0
    @objc dynamic var strokeCount: Int = 0
    @objc dynamic var classification: String = ""
    let kunYomis = List<String>()
    let onYomis = List<String>()
    let longMeanings = List<String>()
    let shortMeanings = List<String>()
    @objc dynamic var radicalComponentCount: Int = 0
    let radicalComponentStrings = List<String>()

    override static func primaryKey() -> String? {
        return "id"
    }
}

Have been at it since yesterday, couldn't figure out what could be wrong. Able to open the database with RealmStudio and all the data appears correct. I'm assuming that this is not a problem with Realm itself but in my definitions but can't figure out. There are three other objects in the database as well.

Can you try to give it an explicit type? 

var kunYomis: [String] = []
var onYomis: [String] = []
var longMeanings: [String] = []
var shortMeanings: [String] = []
var radicalComponentStrings: [String] = []
lingolab2 commented 4 years ago

unfortunately, no positive impact.

Get similar crash even working with another object RLM_Kotowaza with an array. The problem is therefore not specific to RLMKanji.

lingolab2 commented 4 years ago

Don't know if this is really a Realm issue, Unrealm issue or a combination. Have instead decided to use a different approach using a Persistable protocol (https://gist.github.com/gonzalezreal/9d297c68435b9ee12bb1b009afd41d9a) instead of Unrealm.

Could you please send me an example project where can reproduce the crash?

Can I send it via direct email?
