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 13.4.0Crashed: com.apple.main-thread 0 CocoaDebug 0x1023a0adc perform_rebinding_with_section + 332 1 CocoaDebug 0x1023a087c rebind_symbols_for_image + 416 2 libdyld.dylib 0x1999c3f4c invocation function for block in dyld3::AllImages::runImageCallbacks(dyld3::Array const&) + 244 3 libdyld.dylib 0x1999c3768 dyld3::AllImages::runImageCallbacks(dyld3::Array const&) + 160 4 libdyld.dylib 0x1999c8dd8 dyld3::AllImages::loadImage(Diagnostics&, unsigned int, dyld3::closure::DlopenClosure const*, bool, bool, bool, bool) + 580 5 libdyld.dylib 0x1999c89ec dyld3::AllImages::dlopen(Diagnostics&, char const*, bool, bool, bool, bool, bool, void const*) + 868 6 libdyld.dylib 0x1999ca434 dyld3::dlopen_internal(char const*, int, void*) + 364 7 libdyld.dylib 0x1999bd6c0 dlopen + 116 8 CoreFoundation 0x199bcf5c8 _CFBundleDlfcnLoadBundle + 156 9 CoreFoundation 0x199af1eac _CFBundleLoadExecutableAndReturnError + 372 10 Foundation 0x199ec27a8 -[NSBundle loadAndReturnError:] + 316 11 CoreImage 0x19b479bcc invocation function for block in register_more_builtins(void (NSString*) block_pointer) + 804 12 libdispatch.dylib 0x19986833c _dispatch_client_callout + 20 13 libdispatch.dylib 0x199869a68 _dispatch_once_callout + 32 14 CoreImage 0x19b476318 register_more_builtins(void (NSString*) block_pointer) + 304 15 CoreImage 0x19b476b40 classNameIsSystemFilter(NSString*) + 112 16 CoreImage 0x19b476dbc +[CIFilter(CIFilterRegistryPrivate) filterWithName:setDefaults:] + 396 17 MYApp 0x100656598 QRCodeViewController.generateQRCode(from:) + 4370490776 (:4370490776) 18 MYApp 0x1006563a4 QRCodeViewController.viewDidLoad() + 28 (QRCodeViewController.swift:28) 19 MYApp 0x10065642c @objc QRCodeViewController.viewDidLoad() + 4370490412 (:4370490412) 20 UIKitCore 0x19d6a236c -[UIViewController _sendViewDidLoadWithAppearanceProxyObjectTaggingEnabled] + 104 21 UIKitCore 0x19d6a6f20 -[UIViewController loadViewIfRequired] + 952 22 UIKitCore 0x19d6a730c -[UIViewController view] + 32 23 UIKitCore 0x19d602fa4 -[UINavigationController _startCustomTransition:] + 1148 24 UIKitCore 0x19d617478 -[UINavigationController _startDeferredTransitionIfNeeded:] + 692 25 UIKitCore 0x19d618818 -[UINavigationController __viewWillLayoutSubviews] + 176 26 UIKitCore 0x19d5fb4fc -[UILayoutContainerView layoutSubviews] + 228 27 UIKitCore 0x19e1de6a0 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 2168 28 QuartzCore 0x1a08314a0 -[CALayer layoutSublayers] + 292 29 QuartzCore 0x1a08318e0 CA::Layer::layout_if_needed(CA::Transaction*) + 472 30 QuartzCore 0x1a0843dc4 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 144 31 QuartzCore 0x1a0788884 CA::Context::commit_transaction(CA::Transaction*, double) + 304 32 QuartzCore 0x1a07b33d0 CA::Transaction::commit() + 656 33 QuartzCore 0x1a07b3fc8 CA::Transaction::observer_callback(__CFRunLoopObserver*, unsigned long, void*) + 96 34 CoreFoundation 0x199b42c54 __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ + 36 35 CoreFoundation 0x199b3d8e4 __CFRunLoopDoObservers + 420 36 CoreFoundation 0x199b3dd84 __CFRunLoopRun + 1020 37 CoreFoundation 0x199b3d660 CFRunLoopRunSpecific + 480 38 GraphicsServices 0x1a3f4e604 GSEventRunModal + 164 39 UIKitCore 0x19dd1215c UIApplicationMain + 1944 40 MYApp 0x100518e54 main + 4369190484 (:4369190484) 41 libdyld.dylib 0x1999b91ec start + 4I tried several different encoding, I tried to do it on the main thread or in backgroud, but always without result.
