ATS Error: "ATS policy requires the use of a secure connection", despite plist - swift

Question

I'm trying to make a request for an http domain, and despite having
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
<key>NSAllowsArbitraryLoadsInWebContent</key>
<true/>
<key>NSExceptionDomains</key>
<dict>
<key>my-private-domain.kubernetes.intranet%2f:9090</key>
<dict>
<key>NSExceptionAllowsInsecureHTTPLoads</key>
<true/>
<key>NSIncludesSubdomains</key>
<true/>
<key>NSThirdPartyExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSExceptionMinimumTLSVersion</key>
<string>TLSv1.1</string>
</dict>
</dict>
</dict>
at my info.plist for the app target, XCode 12.5.1 keeps me showing the error
Task <C5F9EA01-9790-43ED-89B0-EE07341B4D84>.<4> finished with error [-1022] Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection." UserInfo={NSLocalizedDescription=The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.
I needed to perform this request after updating to 12.5.1 and also tried Clean Build Folder and removing-reinstalling the app. Does someone knows if it's a policy change? (maybe only HTTPS are now allowed even in non-production targets?). The answers I found here only cites NSAllowsArbitraryLoads, NSExceptionDomains, NSExceptionMinimumTLSVersion/NSTemporaryExceptionMinimumTLSVersion and NSThirdPartyExceptionRequiresForwardSecrecy. There's something more?

Answer 1

Because your info.plist includes the NSAllowsArbitraryLoadsInWebContent key, the NSAllowsArbitraryLoads is ignored and treated as false. So removing the NSAllowsArbitraryLoadsInWebContent should allow all arbitrary loads.
Relevant section from Apple docs:
In iOS 10 and later and macOS 10.12 and later, the value of the
NSAllowsArbitraryLoads key is ignored—and the default value of NO used
instead—if any of the following keys are present in your app’s
Information Property List file:
NSAllowsArbitraryLoadsForMedia
NSAllowsArbitraryLoadsInWebContent
NSAllowsLocalNetworking
