From time to time the Vaadin application becomes unresponsive and in the web console I see the following error:
Uncaught (in promise) Error: Client is resynchronizing
https://example.com/VAADIN/build/FlowClient.638236c0.js:1
What might be causing this?

Service worker registered successfully but I'm still getting the above error in chrome.
What verb/action caused the error? You know you can't access the DOM in an SW right?
I'm new to authentication development and am stumped.
When I touch (click on simulator) Sign Up button in the app to submit my user name and password Xcode log shows the following error,
20 Selfie 0x0000000100479707 main + 55
21 libdyld.dylib 0x000000010393d65d start + 1

Further more, this appears when I scroll up, and seems the first signs of an issue
2017-07-13 18:27:42.367 Selfie[75333:3951236] *** Terminating app due
to uncaught exception 'NSInvalidArgumentException', reason: '-
[Selfie.ViewController signupBtnTapped:]: unrecognized selector sent
to instance 0x7fc042c11250'
The desired result is for the app to send the built request to my remote server held by AWS. Here's the pre-dated tutorial I'm using:
https://www.raywenderlich.com/85528/user-accounts-ios-ruby-rails-swift
Here is the repo for the app, in the specific view controller it seems the problem is in, and where I'm left off in the tutorials instruction (at the sign up btn):
https://github.com/tristanbnewman/rwenderlich-auth-selfie/blob/master/Selfie/ViewController.swift
I apologize ahead of time for any etiquettes I've missed in this post, if there's anything you all need to help me solving (likely something I've missed providing you) just let me know.
First of all i would suggest you to make breakpoints on each line of the signupBtnTapped function and see what's happening.
The "unrecognized selector sent to instance" is probably related to how you connect your #IBAction with a button event. Have you connected touchUpInside event with your function in the storyboard?
The first exception is a generic exception which doesn't give much information. Making breakpoints should help you with this.
When loading the main view controller of my app it loads multiple images. Using the sd_setImage(with: reference) method. It has worked forever and now I am suddenly getting crashes with the exception
-[SDImageCache storeImage:forKey:]: unrecognized selector sent to instance 0x600000c60380
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[SDImageCache storeImage:forKey:]: unrecognized selector sent to instance 0x600000c60380'
The stacktrace isn't showing a line in my code that's causing the problem. Is this an internal Firebase bug? How do I fix it?
Firebase calls continuous asynchronous calls to the observer. You should always check for nil or NSNull before attempting to present data from the database. You may have a higher resolution image that takes longer to load than it does your view to appear.
Terminating app due to uncaught exception 'FirebaseShutdown', reason: 'Firebase error. Please ensure that you spelled the name of your Firebase correctly' in ios.
Can any one help me solve this issue?
Using this demo for real time message:

Is there any demo for real time chat in iOS?
The error you're getting is actually from calling [Firebase initWithUrl:] with a URL that isn't backed by a valid Firebase.
This exception is thrown so that you as a developer know that the Firebase you're connecting to is invalid.
If you put in the right Firebase URL, you shouldn't be getting this error.
Could you explain the situation in which you might need to connect to a Firebase that may not be valid?
Note:- You will need to check your base URL for the Firebase, Because you have try to access data from the wrong URL
I'm currently building an App that uses the krpano viewer, which is a Panorama Viewer built with JavaScript. I'm loading this Panorama viewer in a UIWebView with local images that are saved on the iPad.
But after using the Panorama viewer for a while, I get this error and the app crashes:
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[WebCoreSharedBufferData getBytes:range:]: range {0, 4000} exceeds data length 0'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException
Does anyone have an idea why this happens? When I load the online page in the UIWebView there is no problem.
Thanks for your help!
This is probably a memory related issue. When a web application allocates too much memory using Javascript, weird things will happen.
Your best bet is to observe memory warning notifications and try to influence the web app from the outside. Of course this depends on the specifics of the web app but you might want to try disabling userInteractionEnabled for a while to let the web view catch up with queued user input actions or, if the memory warning persists, try to reload the web view.
Unfortunately there are no easy solutions here.
