When I run a react-native project, I get a error no bundle URL present , but I don\'t know what mistakes I do, I was very confused.

Answer 1

Be sure that your ATS settings are correct in .plist file.

You can find the file at /ios/{{project_name}}/Info.plist

localhost must be defined as exception request target like this:

NSAppTransportSecurity
    
    NSExceptionDomains
    
        localhost
        
            NSExceptionAllowsInsecureHTTPLoads
            
        
    

*(dont forget to remove this on release version..)
