RealmSwift: Convert Results to Swift Array

Question

What I want to implement:

class func getSomeObject() -> [SomeObject]? {
    let objects = Realm().objects(SomeObject)

    return objects.count > 0 ? o         


        

Answer 1

Swift 3

extension Results {
    func toArray(ofType: T.Type) -> [T] {
        var array = [T]()
        for i in 0 ..< count {
            if let result = self[i] as? T {
                array.append(result)
            }
        }

        return array
    }
}

Usage

class func getSomeObject() -> [SomeObject]? {
   let defaultRealm = try! Realm()
    let objects = defaultRealm.objects(SomeObject.self).toArray(ofType : SomeObject.self) as [SomeObject]

    return objects.count > 0 ? objects : nil
}

Alternative : Using generics

class func getSomeObject() -> [T]? {
        let objects = Realm().objects(T.self as! Object.Type).toArray(ofType : T.self) as [T]

        return objects.count > 0 ? objects : nil
}
