UIWebView crashed in iOS 10 - swift
I am implementing the LinkedIn sign in using UIWebView
Here is my code
import UIKit
typealias LinkedInLoginCallBack = ([String:String]?,String,Error?) -> Void
class LinkedInWebViewController: UIViewController,UIWebViewDelegate {
#IBOutlet weak var linkedinWebView: UIWebView!

let accessTokenEndPoint = "https://www.linkedin.com/uas/oauth2/accessToken"
override func viewDidLoad() {
super.viewDidLoad()
linkedinWebView.delegate = self
self.startAuthorization()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func startAuthorization() {
let responseType = "code"
let redirectURL = "https://example.com/login/check-linkedin".addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed)!

authorizationURL += "client_id=\(linkedInKey)&"
authorizationURL += "redirect_uri=\(redirectURL)&"
authorizationURL += "state=\(state)&"
authorizationURL += "scope=\(scope)"
// logout already logined user or revoke tokens
logout()
// Create a URL request and load it in the web view.
let request = URLRequest(url: URL(string: authorizationURL)!)
linkedinWebView.loadRequest(request)
}
func logout(){
let revokeUrl = "https://api.linkedin.com/uas/oauth/invalidateToken"
let request = URLRequest(url: URL(string: revokeUrl)!)
linkedinWebView.loadRequest(request)
}

}
}
return true
}
func webViewDidStartLoad(_ webView: UIWebView) {

Webrtc Swift - Thread 1: EXC_BAD_ACCESS (code=1, address=0xd000000000000040)
I am using Janus videoroom with Webrtc. Everything working fine. But when i go for ending call. And dismiss the current view controller - App Crashed.
I am unable to get the point of crashing so i can resolve.
the current view disappeared fine also. Logs shows this:
callDropButton Clicked
Videoroom viewDidDisappear
Videoroom screen dismissed completely
I am getting the crash at this 1st line of Appdelegate:
class AppDelegate: UIResponder, UIApplicationDelegate {
I am also attaching backtrace logs for more info. But this is not making any sence to me:

Make sure you have something like this in your deinit ("screen dismissed completely"?):
rtcAudioSession.remove(self)
peerConnection.close()
[localAudioTrack,
localVideoTrack,
remoteAudioTrack,
remoteVideoTrack,
].forEach { track in
track.isEnabled = false
}
Check on every WebRTC object you've created, if the class have something like close(), isEnabled = false, etc, you should call it in deinit.
According to your crashlog, the problem is in one of RTCVideoTrack objects. Try commenting out all the code that creates any of the RTCVideoTrack and see if that helps. If it helps, uncomment them out one by one to determine which one is causing the problem.
Why does my app keep crashing since iOS 13?
My problem is that my app has been crashing since iOS 13. The app doesn't work on any iPhone anymore. A bit strange, however, is that the iPhone simulators on iOS 13 all work fine. Here is the output of the lldb console after I type bt: * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x48) frame #0: 0x00000001b952d268 AVFAudio`-[AVAudioPlayer(AVAudioPlayerPriv) privRemoveSessionListener] + 16 frame #1: 0x00000001b952b9ac AVFAudio`-[AVAudioPlayer dealloc] + 32 frame #2: 0x0000000100dae9e4 Ducko`#objc StartView.__ivar_destroyer(self=0x0000000101e2de70) at startView.swift:0 frame #3: 0x00000001ac8c01e8 libobjc.A.dylib`object_cxxDestructFromClass(objc_object*, objc_class*) + 112 frame #4: 0x00000001ac8d2d14 libobjc.A.dylib`objc_destructInstance + 88 frame #5: 0x00000001ac8d9db8 libobjc.A.dylib`_objc_rootDealloc + 48 frame #6: 0x00000001b0bd19b8 UIKitCore`-[UIResponder dealloc] + 152 frame #7: 0x00000001e1a40900 UIKit`-[UIResponderAccessibility dealloc] + 60 frame #8: 0x00000001c528e93c SpriteKit`-[SKNode dealloc] + 100 frame #9: 0x00000001c52461dc SpriteKit`-[SKScene dealloc] + 332 frame #10: 0x00000001c526bf54 SpriteKit`-[SKView _update:] + 568 frame #11: 0x00000001c526761c SpriteKit`__51-[SKView _vsyncRenderForTime:preRender:postRender:]_block_invoke.340 + 388 frame #12: 0x00000001c5266a1c SpriteKit`-[SKView _vsyncRenderForTime:preRender:postRender:] + 520 frame #13: 0x00000001c5269bd0 SpriteKit`__29-[SKView setUpRenderCallback]_block_invoke + 200 frame #14: 0x00000001c52ac180 SpriteKit`-[SKDisplayLink _callbackForNextFrame:] + 132 frame #15: 0x0000000101c715f8 GPUToolsCore`-[DYDisplayLinkInterposer forwardDisplayLinkCallback:] + 168 frame #16: 0x00000001b33dd514 QuartzCore`CA::Display::DisplayLink::dispatch_items(unsigned long long, unsigned long long, unsigned long long) + 632 frame #17: 0x00000001b34a7774 QuartzCore`display_timer_callback(__CFMachPort*, void*, long, void*) + 264 frame #18: 0x00000001acaed6d4 CoreFoundation`__CFMachPortPerform + 172 frame #19: 0x00000001acb16e5c CoreFoundation`__CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 56 frame #20: 0x00000001acb16588 CoreFoundation`__CFRunLoopDoSource1 + 444 frame #21: 0x00000001acb1145c CoreFoundation`__CFRunLoopRun + 2168 frame #22: 0x00000001acb108bc CoreFoundation`CFRunLoopRunSpecific + 464 frame #23: 0x00000001b697b328 GraphicsServices`GSEventRunModal + 104 frame #24: 0x00000001b0ba56d4 UIKitCore`UIApplicationMain + 1936 * frame #25: 0x0000000100d777c8 Ducko`main at AppDelegate.swift:14:7 frame #26: 0x00000001ac99b460 libdyld.dylib`start + 4 (lldb) * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=1, address=0x48) frame #0: 0x00000001b952d268 AVFAudio`-[AVAudioPlayer(AVAudioPlayerPriv) privRemoveSessionListener] + 16 frame #1: 0x00000001b952b9ac AVFAudio`-[AVAudioPlayer dealloc] + 32 frame #2: 0x0000000100dae9e4 Ducko`#objc StartView.__ivar_destroyer(self=0x0000000101e2de70) at startView.swift:0 frame #3: 0x00000001ac8c01e8 libobjc.A.dylib`object_cxxDestructFromClass(objc_object*, objc_class*) + 112 frame #4: 0x00000001ac8d2d14 libobjc.A.dylib`objc_destructInstance + 88 frame #5: 0x00000001ac8d9db8 libobjc.A.dylib`_objc_rootDealloc + 48 frame #6: 0x00000001b0bd19b8 UIKitCore`-[UIResponder dealloc] + 152 frame #7: 0x00000001e1a40900 UIKit`-[UIResponderAccessibility dealloc] + 60 frame #8: 0x00000001c528e93c SpriteKit`-[SKNode dealloc] + 100 frame #9: 0x00000001c52461dc SpriteKit`-[SKScene dealloc] + 332 frame #10: 0x00000001c526bf54 SpriteKit`-[SKView _update:] + 568 frame #11: 0x00000001c526761c SpriteKit`__51-[SKView _vsyncRenderForTime:preRender:postRender:]_block_invoke.340 + 388 frame #12: 0x00000001c5266a1c SpriteKit`-[SKView _vsyncRenderForTime:preRender:postRender:] + 520 frame #13: 0x00000001c5269bd0 SpriteKit`__29-[SKView setUpRenderCallback]_block_invoke + 200 frame #14: 0x00000001c52ac180 SpriteKit`-[SKDisplayLink _callbackForNextFrame:] + 132 frame #15: 0x0000000101c715f8 GPUToolsCore`-[DYDisplayLinkInterposer forwardDisplayLinkCallback:] + 168 frame #16: 0x00000001b33dd514 QuartzCore`CA::Display::DisplayLink::dispatch_items(unsigned long long, unsigned long long, unsigned long long) + 632 frame #17: 0x00000001b34a7774 QuartzCore`display_timer_callback(__CFMachPort*, void*, long, void*) + 264 frame #18: 0x00000001acaed6d4 CoreFoundation`__CFMachPortPerform + 172 frame #19: 0x00000001acb16e5c CoreFoundation`__CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 56 frame #20: 0x00000001acb16588 CoreFoundation`__CFRunLoopDoSource1 + 444 frame #21: 0x00000001acb1145c CoreFoundation`__CFRunLoopRun + 2168 frame #22: 0x00000001acb108bc CoreFoundation`CFRunLoopRunSpecific + 464 frame #23: 0x00000001b697b328 GraphicsServices`GSEventRunModal + 104 frame #24: 0x00000001b0ba56d4 UIKitCore`UIApplicationMain + 1936 * frame #25: 0x0000000100d777c8 Ducko`main at AppDelegate.swift:14:7 frame #26: 0x00000001ac99b460 libdyld.dylib`start + 4 Does anyone have any idea how to fix the problem?

How can I prevent the app from crashing after pausing the audio?
my problem is that my app crashes after pausing the audio.
Thread 1: EXC_BAD_ACCESS (code=1, address=0x48)
The sound is played as follows:
var audioPlayer = AVAudioPlayer()
var jumpAudio: URL?
var coinAudio: URL?
...
duck.run(SKAction.playSoundFileNamed("coin", waitForCompletion: true))
I pause the sound in another class by calling this function in the GameScene:
func setAudioOn(pOn: Bool) {
if pOn == true {
audioPlayer.play()
}
else if pOn == false {
audioPlayer.pause()
}
}
Thank you in advance

SIGABRT in Macos application
I'm getting a SIGBART signal after the application is running a while.
I suspect that it is related to timer which is running in the background.
This is the code I'm using to invoke the recurrent timer:
Timer.scheduledTimer(timeInterval: 20 , target: self, selector: #selector(self.scheduledEventHandler), userInfo: nil, repeats: true)
And this is the handler:
#objc func scheduledEventHandler()
{
print("got event")
}
And lastly, this is the stacktrace:

Have got the same problem. Throwing UIAlert on main thread resolved the thing for me. But on ur log stack it seems that you are already one the main thread.
