Help! I'm updating an old Xcode project from 2016 and I'm encountering crashes when working with my Realm objects.
I have a game I built in Xcode with swift 3 and put in the AppStore in 2016. It used Realm for my Game objects. It was one of my first projects so recently I decided to revisit the project and update the code, clean it up (I was very new to Swift), make it work with newer devices and screens, fix a couple bugs, add a few features, etc. When going through the updates to the current languages, I can no longer save my Game object because in 2016, the Realm properties were written as:
dynamic var numCorrect: Int = 0
dynamic var numWrong: Int = 0
dynamic var score: Int = 0
dynamic var stars: Int = 0
dynamic var date = NSDate()
...
Now Realm requires "#objc" before "dynamic var". So it's now:
#objc dynamic var numCorrect: Int = 0
#objc dynamic var numWrong: Int = 0
#objc dynamic var score: Int = 0
#objc dynamic var stars: Int = 0
#objc dynamic var date = NSDate()
With this change/addition everything works great. UNTIL I try to update on top of the old/current version in the App Store. It crashes when trying to create a new Game object.
I assume there's some way to migrate but I can't figure it out. The migration guide doesn't address upgrading from an old version of Realm to a new version.
Here's the log:

Please, does anyone know how to solve this? It's not like this app is popular but I don't want to require any previous user to delete the app in order to use the new version.
I would try to implement a migration block and use enumerate as follows:
migration.enumerateObjects(ofType: Object.className()) { (oldObject, newObject) in
guard let numCorrect = oldObject?["numCorrect"] as? Int else {
fatalError("numCorrect is not a Int")
}
// List all the rest of your properties the same way (i.e., with a guard statement)
// Then assign old object value to new property
newObject?["numCorrect"] = numCorrect
}
Make sure you implement your migration block properly with the right version etc..
For anyone having this problem, it appears to be a bug with Realm's current version. In my podfile I wrote:
pod 'RealmSwift', '<5.0'
pod 'Realm', '<5.0'
And now my project runs perfectly. Thanks #RobertCrabtree!

Since I added translations between two ContentViews (to go from one to the other one nicely), I have the following logs:
This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.

This is my code:
Device.BeginInvokeOnMainThread(async () =>
{
DetailContentView.Children.Insert(0, masterDetailContentView);
await DetailContentView.Children[1].TranslateTo(App.ScreenWidth - 100, 0, 250);
await DetailContentView.Children[1].TranslateTo(App.ScreenWidth, 0, 50);
DetailContentView.Children.RemoveAt(1);
});
where DetailContentView is a Grid, masterDetailContentView is the ContentView that will appear and DetailContentView.Children[1] is the ContentView that will disappear.
This piece of code works but I want to remove the logs.
Thanks!
One of my projects (containing over 200 files in pure Swift) has just recently started interfering with the indexing process. The indexing process freezes midway and then stops abruptly, causing SourceKitService to crash.
I simply cannot find the faulty code; because there appears to be none!
My code compiles just fine (without a single warning!) - and yet it fails to be indexed. Initially, I thought it to be an Xcode 7.2 issue and so upgraded to the latest beta (7.3); however the issue still persists. I cannot revert back to my old code because too much work will be undone, and I can't spot a particular file to blame. The crash report is here.
To clarify, Xcode itself does not crash, only the indexing process (and SourceKitService as a consequence).
Any ideas on how to go about fixing this?
Remove "xcuserdata" from .xcodeproj (right click on .xcodeproj > select Show Package Contents. This should solve the problem.
If I'm reading properly,
the problem comes from this part of the process:

So I guess it's a known issue.
However I don't know what is causing it. I'm pretty sure it's a swift code style that is not well supported yet.
I also found your crash in this Crash test project:

If you look into it, you might find the precise case that triggers one of those crashes:

I'm working for NSCollectionView by using Swift. When I use a NSArrayController object as content of NSCollectionView. I got follow error:
An uncaught exception was raised
[ valueForUndefinedKey:]: this class is not key value coding-compliant for the key plugName .
I have no idea why. I create a model named NHPlug and a NSArrayController as follow, here's my code. :
/* Class NHAppController */
import Cocoa
class NHAppController: NSObject {
#IBOutlet weak var arrayController: NSArrayController?
var plugs: NSMutableArray?
override func awakeFromNib() {
var t = NHPlug(plugID: 1, plugName: "test")
plugs = NSMutableArray()
arrayController?.addObject(t)
}
}
/* Class NSPlug */
import Cocoa
class NHPlug: NSObject {
var plugID : Int
var plugName : String
init(plugID: Int, plugName: String) {
self.plugID = plugID
self.plugName = plugName;
}
}
If anybody could help, very appreciate for that!

Got the answer myself. Post here to help any poor new guy for Swift.
In Swift KVO is not default support any more, when you declare a variable must set "dynamic" as follow:
dynamic var plugID : Int
dynamic var plugName : String
In my cocoa application (written in Swift), I am trying to make a pagination system, where each page is an instance of CASTextView (a subclass of NSTextView). Additionally, each CASTextView retains an instance of CASTextContainer (a subclass of NSTextContainer). In order to accomplish pagination, I have made all instances of CASTextView share the same NSLayoutManager instance via a singleton pattern.
I have implemented the method - (void)layoutManager:(NSLayoutManager *)aLayoutManager didCompleteLayoutForTextContainer:(NSTextContainer *)aTextContainer atEnd:(BOOL)flag as follows:
func layoutManager(layoutManager: NSLayoutManager!,
didCompleteLayoutForTextContainer textContainer: NSTextContainer!,
atEnd layoutFinishedFlag: Bool)
{
let containers = layoutManager.textContainers
if !layoutFinishedFlag || !textContainer {
let lastContainer = containers[containers.count - 1] as NSTextContainer
if !textContainer || textContainer == lastContainer {
if layoutManager.glyphRangeForTextContainer(lastContainer).length > 0 {
addPage(nil)
}
}
}
}
Here is the code to receive the singleton instance of NSLayoutManager (CASTextView.sharedLayoutManager):
class var sharedLayoutManager: NSLayoutManager {
struct Singleton {
static let instance = NSLayoutManager()
}
return Singleton.instance // All text containers share the same layout manager.
}
The method addPage initializes a text view, replaces the text container with one of type CASTextContainer, and then replaces the layout manager with the shared layout manager, as follows:
func addPage(sender: NSNotification?) {
let midpoint = NSWidth(mainView.frame) / 2
let firstEndpoint = midpoint - 500
var rect: NSRect = NSZeroRect
let yValue: CGFloat = 50 + 1425 * CGFloat(pages.count)
mainView.frame.size = NSMakeSize(NSWidth(mainView.frame), yValue + 1675) // extend the scrolling size to account for new subview.
let origin = NSMakePoint(firstEndpoint, yValue)
let size = NSMakeSize(1000, 1375)
rect.origin = origin
rect.size = size
var nextView = CASTextView(frame: rect)
var nextContainer = CASTextContainer(containerSize: containerSize)
nextContainer.mainView = nextView
nextView.replaceTextContainer(nextContainer)
nextContainer.replaceLayoutManager(CASTextView.sharedLayoutManager)
nextView.autoresizingMask = NSAutoresizingMaskOptions.ViewNotSizable
nextView.delegate = nextView
nextView.usesFindPanel = true
mainView.addSubview(nextView)
pages.append(nextView)
for var i = 0; i < pages.count - 1; ++i {
pages[i].nextPage = pages[i + 1] // reset nextPage variable
}
}
Each CASTextView retains a reference to the next page (also of type CASTextView), and the last CASTextView is to have this reference (called nextPage) set to nil. The variable 'pages' is an array of all of the pages retained by the NSLayoutManagerDelegate (a subclass of NSViewController).
The problem: The call to addPage is executing exactly when it is intended to (when one page's text container can no longer fit all of the text), but is causing an exception to occur in the following method:
-[NSBigMutableString _getBlockStart:end:contentsEnd:forRange:stopAtLineSeparators:]: Range {0, 98} out of bounds; string length 0
I cannot find documentation on this method anywhere; the leading underscore seems to imply that it is a private method of NSString, but the stack trace shows that it is being called by -[NSString paragraphRangeForRange:] . Interestingly, the stack trace does not show that the addPage method is on the stack. Here is the stack trace:

The error was occurring as a result of my call to replaceLayoutManager. I altered the way that I initialize the text view. Rather than using the init(frame: frameRect) constructor, I utilized the designated initializer by separately initializing a text container as such:
var nextContainer = CASTextContainer(containerSize: containerSize)
var nextView = CASTextView(frame: rect, textContainer: nextContainer)
I then proceeded to call mainView.addSubview(nextView), and after the subview was added, I called the following:
CASTextView.sharedLayoutManager.addTextContainer(nextContainer)
which then allowed for the pagination effect to take place.
I am trying to run on Monodevelop (latest Git) a solution that runs fine on Xamarin.Mac
It crashes at the base() line:
public class SetupWindow : NSWindow {
public List <NSButton> Buttons = new List <NSButton> ();
public string Header;
public string Description;
private NSImage side_splash;
private NSImageView side_splash_view;
private NSTextField header_text_field;
private NSTextField description_text_field;
public SetupWindow () : base ()
{
SetFrame (new RectangleF (0, 0, 640, 420), true);
With this output:

Any idea what is going wrong?
Because of another problem, I commented out the lines that set images for NSApplication.SharedApplication.ApplicationIconImage and NSWorkspace.SharedWorkspace.SetIconforFile, could that be the problem?
A colleague tried on his brand new Mac, and gets the exact same problem.
The problem was fixed by adding these two lines before instantiating SetupWindow:
NSApplication.SharedApplication.ApplicationIconImage = image;
SetFolderIcon ();
Now the application runs fine.
