Instead of the correct one as below

            NSExceptionAllowsInsecureHTTPLoads
            
        
    

I was having this

    NSAllowsArbitraryLoadsInWebContent
    
    NSAllowsArbitraryLoads
    
    NSExceptionDomains
    
        some-service1.com
        
            NSExceptionAllowsInsecureHTTPLoads
            
        
        some-service2.com
        
            NSExceptionAllowsInsecureHTTPLoads
            
        
    

Although some of the online XML Validators did say the XMLs are correct, (which was not), I used

plutil filename.plist

going to the directory where plist file is present (from terminal) and got to know the exact line number that had issues Reference :(https://stackoverflow.com/a/32494850/5438240)
