问题 I am new to using Realm. Is there an easy way to save an array to a realm object? I am receiving my data from a JSON REST call: class SomeClass: RLMObject { dynamic var id = 0 dynamic var name = "" dynamic var array: NSArray func checkForUpdates() { // Download JSON data here... The results have an array inside of them. SomeClass.createOrUpdateInDefaultRealmWithObject(SomeNSDictionary) } override class func primaryKey() -> String! { return "id" } } Is it possible to save the array in the JSON

问题 just wondering, how do I convert List to Result? Cause I'm doing filtering of region and areas, and when user selected region then area should show only those area in the region.

问题 I'm wondering about Realm's query performance. Given this code: let result1 = realm.objects(Person.self).filter("age < 30 AND ... AND ...") let result2 = realm.objects(Person.self).filter({ $0.age < 30 }).filter({$0.name .... }).filter({$0.nickname ...}) result1 is created by filtering Person objects using an NSPredicate , while result2 is filtering using the filter method from Swift's collection types. Is there a performance difference between these two approaches to filtering? 回答1: Yes,

问题 Sometimes (rarely but occurs) I got error Object has been deleted or invalidated. , when trying to modify my model object with a property or inside AFnetworking Block.

问题 I have got a Realm object class, and storing lots of data in there, imagine that I have a String uid; field. I want to get uid names, but on same uid names just only one time, For example uid AA AA BB CC DD BB BB I want to get just AA, BB, CC, DD. Only one time.

问题 I can't seem to get the https proxy for my Realm Object Server running.

Maybe it's not the proper way to share a table between users? static public func setGlobalDatabase(database:String, completion: @escaping (_ realm: Realm?, _ error: Error?) -> Void) { let realmPath = RealmService.REALM_SERVER_DATA + "/" +
