Segmentation fault: 11 - Xcode 10

  1. While type-checking statement at RangeText="{ playlistNames = [] let requestLibrary = NSFetchRequest(entityName: "Library")

    let request = NSFetchRequest<NSFetchRequestResult>(entityName: "Playlist")
request.sortDescriptors = [playlistSortDescriptor]

playlists = try? context.fetch(request) as NSArray!
print("Playlist Count - ",playlists.count)


let librarys:NSArray! = try? context.fetch(requestLibrary) as NSArray!
for library in librarys{
    let libraryName = (library as AnyObject).value(forKey: "library") as! String
    playlistNames += [libraryName]
}

for playlist in playlists{
    let playlistName = (playlist as AnyObject).value(forKey: "playlistName") as! String
    if playlistName == "Library" {
        playlistNames.insert(playlistName, at: 0)
    }else {
        playlistNames += [playlistName]
    }
}

    }"

  2. While type-checking expression at RangeText="playlists = try? context.fetch(request) as NSArray!" error: Segmentation fault: 11

Here is the code:

 func refreshPlaylists(){
    playlistNames = []
    let requestLibrary = NSFetchRequest<NSFetchRequestResult>(entityName: "Library")

    let request = NSFetchRequest<NSFetchRequestResult>(entityName: "Playlist")
    request.sortDescriptors = [playlistSortDescriptor]

    playlists = try? context.fetch(request) as NSArray!
    print("Playlist Count - ",playlists.count)


    let librarys:NSArray! = try? context.fetch(requestLibrary) as NSArray!
    for library in librarys{
        let libraryName = (library as AnyObject).value(forKey: "library") as! String
        playlistNames += [libraryName]
    }

    for playlist in playlists{
        let playlistName = (playlist as AnyObject).value(forKey: "playlistName") as! String
        if playlistName == "Library" {
            playlistNames.insert(playlistName, at: 0)
        }else {
            playlistNames += [playlistName]
        }
    }
}

It works before i updated to Xcode 10. Any idea ?

There is no such type as NSArray! and in any case there was never any reason for you to cast to it. Delete as NSArray! throughout. Use Swift types.
