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

With Swift 4.2 it's as simple as an extension:

extension Results {
    func toArray() -> [Element] {
      return compactMap {
        $0
      }
    }
 }

All the needed generics information is already a part of Results which we extend.

To use this:

let someModelResults: Results = realm.objects(SomeModel.self)
let someModelArray: [SomeModel] = someModelResults.toArray()
