Create a new project.
Install Realm via CocoPods

Version of Realm and Tooling

Realm framework version: ? 2.8.3

Realm Object Server version: ?

Xcode version: ? 9 beta 3

Can confirm this is a problem when building with Swift 4 and Xcode 9 beta 3 and using CocoaPods.

Thanks for your patience as we update Realm Objective-C and Realm Swift to support Xcode 9 beta 3, released this morning.

No worries. It’s a beta. Just wanted you to be aware.

Addressed in #5107 and #5109.

Well that error went away, however, now getting a few others ones.

// LinkingObjects.swift:109:16: Use of unresolved identifier 'RLMDescriptionWithMaxDepth'
return RLMDescriptionWithMaxDepth("LinkingObjects<\(rlmResults.objectClassName)>", rlmResults, RLMDescriptionMaxDepth)

// RealmSwift/List.swift:35:16: Use of unresolved identifier 'RLMDescriptionWithMaxDepth'
return RLMDescriptionWithMaxDepth("List<\(_rlmArray.objectClassName)>", _rlmArray, depth)

// RealmSwift/Object.swift:101:43: Type 'RLMSchema' has no member 'partialPrivateShared'
super.init(value: value, schema: .partialPrivateShared())

// RealmSwift/Results.swift:84:16: Use of unresolved identifier 'RLMDescriptionWithMaxDepth'
return RLMDescriptionWithMaxDepth("Results<\(rlmResults.objectClassName)>", rlmResults, RLMDescriptionMaxDepth)

// RealmSwift/Sync.swift:128:16: Value of type 'NSError' has no member '__rlmSync_deleteRealmBlock'
return _nsError.__rlmSync_deleteRealmBlock()

Wasn't sure if I should open a new issue or just update this one, just wanted you guys to be aware of this.

Are you using CocoaPods, and are you pointing both the Realm and RealmSwift pods to master? Looks like your Realm pod is out of date but you're using the latest RealmSwift pod...

[luispadron]

You were correct, my mistake!

I hadn't added the Realm pod to my podfile after pointing RealmSwift to master

Adding Realm as a pod fixed it

  pod 'Realm',      :git => "https://github.com/realm/realm-cocoa.git", 
                    :branch => "master", 
                    :submodules => true
