Xcode crash on opening .xcodeproj file

Question

I am running my React-Native iOS project with Xcode but I don't know which change effects it and my I notices that my Xcode is crashed then I try to open it inside Xcode but it crashes every time then I deleted derived data and also xcuserdata from .xcodeproj file but no success I also tried to use this command "defaults delete com.apple.dt.Xcode" but again no luck I have also looked into .xcodeproj file for conflicts but there is no conflicts I try to run my project with command line but again got this message.

"error Failed to build iOS project. We ran `xcodebuild` command but it exited with error code null. To debug build logs further, consider building your app with Xcode.app, by opening `.xcodeproj`

Can anyone please suggest me a solution for this ?

Delete derived data of xcode and also of project. react-native run-ios

"error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code null. To debug build logs further, consider building your app with Xcode.app, by opening Raydan.xcodeproj"

Answer 1

I tried almost everything on the internet like.

1. Deleting Xcode derived data .
2. Try with .workspace file .
3. Deleting xcuserData .

but nothing works, At last, I found this problem with react-native-fast-image , upgrading to react-native-fast-image v7.0.0 was causing the problem so downgrading react-native-fast-image to v5.1.2 works for me.

here is the issue reported in their Github.

In my personal experience working with React-Native and XCode you should try deleting the build folder for android and/or iOS for whichever you are using it for. Every time you run your code it should re-create a new build once it is deleted.
