…37878) Summary: See: http://blog.nparashuram.com/2019/10/debugging-react-native-ios-apps-with.html When using direct debugging with JavaScriptCore, Safari Web Inspector doesn't pick up the source map over the network. Instead, as far as I can tell, it expects you to pass the source URL at the time you load your bundle: https://developer.apple.com/documentation/javascriptcore/jscontext/1451384-evaluatescript?language=objc . This leads to a very sub-par developer experience debugging the JSbundle directly. It will however, pick up an inline source map. Therefore, let's add a way to have React Native tell metro to request an inline source map. I did this by modifying `RCTBundleURLProvider` to have a new query parameter for `inlineSourceMap`, and set to true by default for JSC. [IOS] [ADDED] - Added support to inline the source map via RCTBundleURLProvider Pull Request resolved: facebook#37878 Test Plan: I can put a breakpoint in RNTester, via Safari Web Inspector, in human readable code :D <img width="1728" alt="Screenshot 2023-06-14 at 4 09 03 AM" src="https://github.com/facebook/react-native/assets/6722175/055277fa-d887-4566-9dc6-3ea07a1a60b0"> Reviewed By: motiz88 Differential Revision: D46855418 Pulled By: huntie fbshipit-source-id: 2134cdbcd0a3e81052d26ed75f83601ae4ddecfe
