Answer 1

• Failure Reason: You don't have permission.

First of all please be sure that delete the derived data

If it didn't work then change permission for Terminal . Detail link is here

Probably you would not need this but just in case:

Maybe disabling system integrity protection with csrutil disable works for you.

Highly recommend you to read the Apple document first.

Answer 2

I also had this problem when I used react-native to create a new project.I had solved this problem.

System Information macOS Version 10.14.4 Xcode 11.3.1 (16142)

run "react-native --version" in project directory. The version is "react-native: 0.64.0". I used "npx react-native init interview --version 0.63.4" to create a new project.It worked!

So I guess use the older version to create a new project can solve your problem.
