Terminating app due to uncaught exception 'NSInternalInconsistencyException'

[ghost]

I am getting this error, after I hit Back in the navigation controller. My ChatViewController (which uses ReverseExtension) is succesfully deiniting as you can see from the logs below, also another observer that I use (ContextWatcher) is deiniting as well.

I put a break point in deinit and the below error occures before the break point. Any ideas?

[00070]:ChatViewController.swift :deinit........................ :10:26:52 -------------------------
[00071]:ChatViewController.swift :deinit........................ :10:26:52 | ViewController deinit |
[00072]:ChatViewController.swift :deinit........................ :10:26:52 -------------------------
[00075]:CDContextWatcher.swift :deinit........................ :10:26:52 DEINIT ContextWatcher

removeObserver is called this line.
But tableView might sometimes already be released because it is weak reference.
Please call tableView.removeObserver(self, forKeyPath: #keyPath(UITableView.contentInset)) in your ViewController's deinit.

Doesn't seem to work. Could it be because self refers to different things? ChatViewController in my app, and something else in ReverseExtension? I get an error exactly at that specific code now, the one I just inserted in deinit. Maybe you could make a function deinitReverseExtenion(), so that I can call it in viewcontroller's deinit.

I've fixed removeObserver timing at 0.4.2!
Please try it.

[ghost]

Didn't work.

For further info I am testing it on an actual device, iPhone 6S. Also, outlet is defined as: @IBOutlet var tableView: UITableView! if that makes a difference. I also cleared derived data and cleaned the project.

[marty-suzuki]

Do you try this?

tableView.removeObserver(tableView.re, forKeyPath: #keyPath(UITableView.contentInset))

[ghost]

No didn't. But I just did NOW, and it works!. Thank you.

[marty-suzuki]

I've fixed v0.4.3 without using tableView.removeObserver(tableView.re, forKeyPath: #keyPath(UITableView.contentInset))!

The default version installed via Cocapods (0.4.1) is still affected by this issue.

[marty-suzuki]

Latest version is 0.4.5
Please use that version.
