RealmSwift + Rx

RxRealmDelete.swift

func delete<T>(type: T.Type, code: String) -> Observable<()> where T: Object {
        return Observable.create { observer in
            do {
                let realm = try Realm()
                guard let object = realm.objects(type).filter(code).first else { return Disposables.create() }
                realm.delete(object)
                observer.onNext(())
                observer.onCompleted()
            } catch let error {
                observer.onError(error)
            }
            return Disposables.create()
        }
    }

thanks for your questions.
I think the first thing to do is to specify a T: Object and prepare a deletable method.
Next I thought it would be good to create a method if you want to filter by items other than keys

example)

    static func delete<T>(element: T) -> Observable<()> where T: Object {
        return Observable.create { observer in
            do {
                let realm = try Realm()
                try realm.write {
                    realm.delete(element)
                    observer.onNext(())
                    observer.onCompleted()
                }
            } catch let error {
                observer.onError(error)
            }
            return Disposables.create()
        }
    }

    static func deleteBy<T>(element: T, code: String) -> Observable<()> where T : Object {
        return Realm.query(type: T.self, formattedString: NSPredicate(format: "code == %@", argumentArray: [code]))
            .flatMap { Realm.delete(element: $0) }
    }

(* I have not actually operated it)
Thank you!

I fixed it so that it compiles!
