I have an app which connects to a server to call APIs using IP address, I don't have a domain associated with it. I have tried following solution in plist.info file, but still i receive same error.
NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection
It looks like you can't use hard coded IP Addresses. Please refer to this answer for more info.
Hard-coded IP address wont work in iOS9. I also faced the same issue. Tried all permutations & combinations of available solutions. Finally, had to use a proper domain name.
