I wanted to do testing in ios 13 for that I needed xcode v11 so after upgrading to xcode 11.5 and then after running my project in simulator(ios 13). I was facing the following error.
enter image description hereThis exception was coming after a successful build.
Investigating about it online, there was a suggestion to upgrade the react and react-native versions. So I upgraded to the latest versions i.e "16.0.0-alpha.12" and "0.62.2" respectively and restarted Xcode. Afterwhich whole lot of errors started coming based on version dependencies, due to which I reverted the changes back to the initial stage.And then I clicked on Product->Clean build folder in Xcode and restarted xcodeNow after this when I am trying to build the project in simulator, the build is failing giving this error in build timeenter image description here
Aim : I want my project to run successfully in simulator. As it was running before upgrading to xcode 11.
P.S - Here is my project's package.json in react-native.
