I just integrated AdMob into my project and I get a whole bunch of these error messages in the Xcode output.
The app does not communicate w/ the internet and does not open up WKView (all I found n SO was references to WKWebView like this https://stackoverflow.com/a/44623268/14414215 but doesn't seem to be related to me since I don't use WKWebView). All I did was integrate Google-Mobile-Ads using cocoa pods and followed the Admob support pages.
Some SO Pages talk about ATS, but google support pages don't have the same error message (https://developers.google.com/admob/ios/app-transport-security)
App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.
Its happening both on simulator and real device. Is this a real issue or something I can ignore?
Also, there's a ton of messages coming out from the Admob SDK, it's frankly a bit annoying to filter through.
