I have a SKEffectNode that contains a node that will change it's children dynamically through times (Remove children and add children dynamically very often). And I keep getting this crash log (only happens on iOS10) on Fabric however i cannot reproduce it on my own devices. The log seems likes it is trying to calculate the bounds of this node and get some errors.
Does anyone has the same situation? plz give me sound suggestions and advices. Thanks!

All init of CIFilter causes a crash for some devices iPhone 11 & iPhone XR. iOS version 13.3.1, 13.4.1.
I tried to import :
import CoreImage
import CoreImage.CIFilter
import CoreImage.CIFilterBuiltins
But Its not working !
I use xCode 11.4.1 & xCode 11.5
I have tried several things:
if let filter = CIFilter(name: "CIQRCodeGenerator") {
filter.setValue(data, forKey: "inputMessage")
let transform = CGAffineTransform(scaleX: 5, y: 5)
if let output = filter.outputImage?.transformed(by: transform) {
return UIImage(ciImage: output)
}
}
or this :
let filter = CIFilter.qrCodeGenerator()
I also tried to link to CoreImage.framework explicitly in the target settings.

With the simulator it works well.
Someone would have any idea ?
Thanks
I figured out how to fix it.
The problem was the third-party CocoaDebug !
I remove the pod and I have no more crashes!
Thanks!
I'm trying to generate QR code with following code :
DispatchQueue.main.async {
let image = generateQRCode(from: qrCodeString)
}
func generateQRCode(from string: String?) -> UIImage? {
if let data = string?.data(using: .utf8, allowLossyConversion: false) {
if let filter = CIFilter(name: "CIQRCodeGenerator") {
filter.setValue(data, forKey: "inputMessage")
let transform = CGAffineTransform(scaleX: 5, y: 5)
if let output = filter.outputImage?.transformed(by: transform) {
return UIImage(ciImage: output)
}
}
}
return nil
}
This code works well for most devices/iOS version.
But firebase brings me a lot of device crashes: iPhone 11, XR. iOS 13.4.0

I tried several different encoding, I tried to do it on the main thread or in backgroud, but always without result.
it looks like the whole class CIFilter causes a crash !!

I am having a lot of Sprite Kit crashes in iOS 9. The below are logs I am getting. I don't think this has anything to do with my code and seems more like a SpriteKit bug in iOS 9. Anyone else faced the same issue and resolved yet?

The callstack is below. I have been kinda stumped about this. The app crashes randomly with this callstack. The only clue I have is its always when the user is dealing with UIWebViews.
Could it be possibly because that I am not nilling out the webview delegates, or some video elements in the page that is being rendered? Has anyone seen something similar?
Thanks!
The UIWebView is a child of a view in a UIViewController.
The viewDidLoad is where the webView is initialized
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.webView.delegate = self;
self.webView.scalesPageToFit = YES;
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:self.startingUrl]]];
}

UIWebView load html contains audio or vedio label, will random crash. This is WebKit's bug when allocateVolumeView. Now i has fixed this bug.
see my answer
After release ios 8.3 i began getting a crash reports from users, i can't figure out on which version of ios it is occurred, only i have is this crash report...
I think this is Sprite Kit bug and i also think that this occurs when app is going to background.
