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

This an another way of converting Results into Array with an extension with Swift 3 in a single line.

extension Results {
    func toArray() -> [T] {
        return self.map { $0 }
    }
}

For Swift 4 and Xcode 9.2

extension Results {
    func toArray(type: T.Type) -> [T] {
        return flatMap { $0 as? T }
    }
}

With Xcode 10 flatMap is deprecated you can use compactMap for mapping.

extension Results {
    func toArray(type: T.Type) -> [T] {
        return compactMap { $0 as? T }
    }
}
