>+        * NetworkProcess/cocoa/NetworkDataTaskCocoa.h: Use __strong for an in/out argument.
>+        * NetworkProcess/cocoa/NetworkDataTaskCocoa.mm:
>+        (WebKit::NetworkDataTaskCocoa::applySniffingPoliciesAndBindRequestToInferfaceIfNeeded):
>+        Use __strong for a in/out argument.
>+        (WebKit::NetworkDataTaskCocoa::applyCookieBlockingPolicy): Call a NSURLSessionTask
>+        method using an explicit category declaration rather than by using performSelector:
>+        since ARC is unable to correctly compile a call when it doesn't know argument and
>+        result types.
>+
>+        * PluginProcess/mac/PluginProcessMac.mm:
>+        (WebKit::initializeCocoaOverrides): Add some __bridge casts.
>+
>+        * Shared/API/Cocoa/WKRemoteObjectCoder.mm: Use HashSet<CFTypeRef> instead of
>+        HashSet<Class> since Class ia an ARC-managed type and WTF hash tables can't
>+        currently handle those as key types.
>+        (-[WKRemoteObjectDecoder decodeValueOfObjCType:at:]): Changed types and added casts
>+        to adapt to the above.

>+        * Shared/API/c/cf/WKStringCF.mm:
>+        (WKStringCreateWithCFString): Use CFRetain instead of -[NSObject retain]. Also use
>+        a __bridge cast.
>+        * Shared/API/c/cf/WKURLCF.mm:
>+        (WKURLCreateWithCFURL): Ditto.

>+        (API::Object::wrap): Use a __bridge cast.
>+        (API::Object::unwrap): Ditto.
>+
>+        * Shared/RemoteLayerTree/RemoteLayerTreePropertyApplier.h: Use CFTypeRef for layers
>+        or views in the RelatedLayerMap since we don't want the items retained, and can't
>+        use __unsafe_uretained because the header is used in non-Objective-C contexts.
>+        * Shared/RemoteLayerTree/RemoteLayerTreePropertyApplier.mm:
>+        (WebKit::RemoteLayerTreePropertyApplier::applyProperties): Added __bridge casts,
>+        needed because of the above change.
>+
>+        * UIProcess/API/Cocoa/WKBrowsingContextController.mm:
>+        (WebKit::browsingContextControllerMap): Use __unsafe_unretained.
>+
>+        * UIProcess/API/Cocoa/WKConnection.mm:
>+        (didReceiveMessage): Use a __bridge cast.
>+
>+        * UIProcess/API/Cocoa/WKContentRuleListStore.mm:
>+        (-[WKContentRuleListStore compileContentRuleListForIdentifier:encodedContentRuleList:completionHandler:]):
>+        Use a retain here so we don't have to have a "releasesArgument:" boolean. The cost of a single
>+        retain/release pair should be infinitesmal compared to the entire process of compiling.
>+        (-[WKContentRuleListStore _compileContentRuleListForIdentifier:encodedContentRuleList:completionHandler:]):
>+        Moved the code for the "releases argument" version here since the private method is now the
>+        actual method that does the work. The public method now simply calls this private one after
>+        doing a retain. The optimization of releasing the argument at the correct moment should be intact.
>+
>+        * UIProcess/API/Cocoa/WKHTTPCookieStore.mm: Use CFTypeRef for the key to the _observers
>+        HashMap since the WTF collections can't yet handle ARC types for keys.
>+        (-[WKHTTPCookieStore addObserver:]): Added __bridge cast for compatibility with the above.
>+        (-[WKHTTPCookieStore removeObserver:]): Ditto.
>+
>+        * UIProcess/API/Cocoa/WKProcessGroup.mm:
>+        (setUpConnectionClient): Added a __bridge cast.
>+        (setUpHistoryClient): Ditto.
>+
>+        * UIProcess/API/Cocoa/WKViewPrivate.h: Added a declaration of the
>+        -[WKView _shouldLoadIconWithParameters:completionHandler:] method. This peculiar idiom
>+        should be removed, but I didn't bother doing that since the entire WKView class is already
>+        deprecated and so will eventually be removed.
>+
>+        * UIProcess/API/Cocoa/WKWebView.mm: Use __unsafe_unretained for the keys in the page to
>+        view map.
>+        (accessibilityEventsEnabledChangedCallback): Use a __bridge cast.
>+        (-[WKWebView _certificateChain]): Ditto.
>+        (-[WKWebView certificateChain]): Ditto.
>+
>+        * UIProcess/API/Cocoa/_WKAttachment.mm:
>+        (isDeclaredOrDynamicTypeIdentifier): Use __bridge casts.
>+        (-[_WKAttachmentInfo mimeType]): Ditto. Also use bridgingAutorelease.
>+        (-[_WKAttachmentInfo utiType]): Ditto.
>+
>+        * UIProcess/API/mac/WKView.mm:
>+        (-[WKView maybeInstallIconLoadingClient]): Call the method
>+        _shouldLoadIconWithParameters:completionHandler: in a normal way rather than using
>+        performSelector:withObject:withObject: since ARC is unable to correctly compile a call
>+        when it doesn't know argument and result types.
>+
>+        * UIProcess/Cocoa/NavigationState.mm:
>+        (WebKit::NavigationState::NavigationClient::webCryptoMasterKey): Use the overload
>+        of API::Data::createWithoutCopying that knows how to work with an NSData rather than
>+        re-implementing it here.
>+        * UIProcess/Cocoa/WebProcessPoolCocoa.mm:
>+        (WebKit::WebProcessPool::platformInitializeWebProcess): Ditto. Also removed unneeded
>+        use of RetainPtr.
>+
>+        * UIProcess/Cocoa/WebViewImpl.h: Use NSObject * as the result type of
>+        immediateActionAnimationControllerForHitTestResult. Our techniques for defining such
>+        functions in headers while remaining compatible with non-Objective-C will still work
>+        fine given how we use this, and converting to and from void* rather than NSObject *
>+        would be difficult to do correctly under ARC.
>+
>+        * UIProcess/Cocoa/WebViewImpl.mm:
>+        (WebKit::WebViewImpl::acceptsFirstMouse): Use CFRetain/CFAutorelease instead of
>+        retain/autorelease.
>+        (WebKit::WebViewImpl::shouldDelayWindowOrderingForEvent): Ditto.
>+        (WebKit::WebViewImpl::immediateActionAnimationControllerForHitTestResult):
>+        Updated return type to NSObject *.
>+        (WebKit::WebViewImpl::performKeyEquivalent): Use CFRetain/CFAutorelease.
>+
>+        * UIProcess/PageClient.h: Use NSObject * as the result type, as above.
>+
>+        * UIProcess/RemoteLayerTree/RemoteLayerTreeHost.mm:
>+        (WebKit::RemoteLayerTreeHost::updateLayerTree): Use __bridge casts to be compatible
>+        with the changes to the RelatedLayerMap types.
>+        (WebKit::recursivelyMapIOSurfaceBackingStore): Use __bridge cast.
>+
>+        * Source/WebKit/UIProcess/WebPageProxy.cpp:
>+        (WebKit::WebPageProxy::immediateActionAnimationControllerForHitTestResult):
>+        Use NSObject * as the result type, as above.
>+        * Source/WebKit/UIProcess/WebPageProxy.h: Ditto.
>+
>+        * UIProcess/mac/PageClientImplMac.h: Use NSObject * as the result type, as above.
>+        * UIProcess/mac/PageClientImplMac.mm:
>+        (WebKit::PageClientImpl::immediateActionAnimationControllerForHitTestResult):
>+        Ditto.
>+        (WebKit::PageClientImpl::refView): Use __bridge cast.
>+        (WebKit::PageClientImpl::derefView): Ditto.
>+
>+        * UIProcess/mac/ServicesController.mm:
>+        (WebKit::ServicesController::refreshExistingServices): Removed unnecessary use
>+        of NeverDestroyed for Objective-C object pointers. Simpler and more efficient
>+        both with and without ARC.
>+
>+        * UIProcess/mac/WKImmediateActionController.mm:
>+        (-[WKImmediateActionController _updateImmediateActionItem]): Removed unneeded
>+        cast now that immediateActionAnimationControllerForHitTestResult has a more
>+        accurate return type.
>+
>+        * UIProcess/mac/WKPrintingView.mm:
>+        (-[WKPrintingView dealloc]): Use a more direct approach to making sure we do the
>+        non-thread-safe actions on the main thread with a call to callOnMainThread.
>+        The old solution, WebCoreObjCScheduleDeallocateOnMainThread, may not be possible
>+        in an ARC-compatible way, but this one should work fine.
>+        (linkDestinationName): Changed to return an NSString * to make sure we get the
>+        object lifetimes correct under ARC.
>+        (-[WKPrintingView _drawPDFDocument:page:atPoint:]): Added __bridge casts.
>+
>+        * WebProcess/InjectedBundle/API/mac/WKDOMInternals.h: Use __unsafe_unretained
>+        for the value types in DOM caches.
>+        * WebProcess/InjectedBundle/API/mac/WKDOMInternals.mm:
>+        (WebKit::toWKDOMNode): Updated for the above.
>+        (WebKit::toWKDOMRange): Ditto.
>+
>+        * WebProcess/Plugins/Netscape/mac/NetscapePluginMac.mm:
>+        (WebKit::NetscapePlugin::platformPreInitialize): Rewrote the class_replaceMethod
>+        call to sidestep the rules about not using @selector(release) under ARC.
>+        (WebKit::NetscapePlugin::updatePluginLayer): Use __bridge casts.
>+
>+        * WebProcess/Plugins/PDF/PDFPlugin.mm: Added an include of
>+        WebAccessibilityObjectWrapperMac.h, without which this code doesn't compile
>+        under ARC.
>+
>+        * WebProcess/WebCoreSupport/mac/WebEditorClientMac.mm:
>+        (WebKit::changeWordCase): Use a function rather than a selector, since ARC is unable
>+        to correctly compile a method call when it doesn't know argument and result types.
>+        (WebKit::WebEditorClient::uppercaseWord): Updated to use a function rather than a selector.
>+        (WebKit::WebEditorClient::lowercaseWord): Ditto.
>+        (WebKit::WebEditorClient::capitalizeWord): Ditto.
>+
>+        * WebProcess/cocoa/WebProcessCocoa.mm: Added an include of
>+        WebAccessibilityObjectWrapperIOS/Mac.h, without which this code doesn't compile
>+        under ARC.
