Probable bug in Swift and Parse-iOS-SDK 1.5.0
I have a Swift project where I pin some data to PFUser object. It is an array of PFObject subclasses:
PFUser.currentUser()["posts"] = [post1, post2]When I try to fetch all the data and cast it to Swift Array it crashes with fatal error: NSArray element failed to match the Swift Array Element type error.
func printCurrentPosts() {
let posts = PFUser.currentUser()["posts"] as [Post]
println("posts: \(posts)") //crashes
}When I cast it to general [PFObject] array it works and prints its content properly.
func printCurrentPostsAsPFObjectArray() {
let posts = PFUser.currentUser()["posts"] as [PFObject]
println("posts: \(posts)") //works
}When I fetch the data in saveAllInBackground: completion closure it can be casted to subclass array without error:
PFObject.saveAllInBackground([post1, post2, PFUser.currentUser()], block: { (success, error) -> Void in
let posts = PFUser.currentUser()["posts"] as [Post]
println("posts: \(posts)") //works
})See ViewController.swift file for implementation. You can run this project in simulator to check each variant.
Using Parse SDK 1.5.0
What am I doing wrong?
