Using enum as property of Realm model

You should override your kindEnum's setter and getter for this case:

enum Kind: String {  case CheckedIn  case EnRoute  case DroppedOff}class Checkin: Object {  @objc dynamic var id = 0  var kind = Kind.CheckedIn.rawValue  var kindEnum: Kind {    get {      return Kind(rawValue: kind)!    }    set {      kind = newValue.rawValue    }  }}

I've refined this model a little further.

enum Thing: String {    case Thing1    case Thing2    case Thing3}

then in my Realm class object:

class myClass : Object {    private dynamic var privateThing = Thing.Thing1.rawValue    var thing: Thing {        get { return Thing(rawValue: privateThing)! }        set { privateThing = newValue.rawValue }    }}

This allows us to write

myClassInstance.thing = .Thing1

(storing "Thing1" into privateThing), but prevents typing of

myClassInstance.privateThing = "Thing4"

which is not a valid value so preserving data integrity.

Since Realm support Objective-C enums and they are representable by Int you can use this:

class Checkin: Object {  dynamic var id: Int = 0  dynamic var kind: Kind = .checkedIn  @objc enum Kind: Int {    case checkedIn    case enRoute    case droppedOff  }  ....}

If you need to parse to/from String you can use a custom initializer for Kind and an toString function.

There is a discussion about this in GitHub

This works with Swift 3.0 and Realm 2.0.2
