I am receiving this warning in my debugger in xcode 8, iOS-10, when I using UIWebView Delegate methods to load something. I didn't find any documentation in Apple website about this web filter Active/De-active mode. Though it's not causing any problem in my existing webView functionality even I am running some javascript function in my webView did finished method. But still curious to know more about this new feature.

Any suggestion about this feature will be appreciate.

Answer 1

According to Apple, the "Content Security Policy(CSP)" which support in Safari 10 has been enhanced by including version 2.0 of the standard. It seems that this feature includes in iOS 10 as well.

For more information please look here about the CSP levels: https://content-security-policy.com

OR

Check the site with Chrome Developer Tools and you will find most likely a warning like Mixed Content: The page at '...' as loaded over HTTPS, but requested an insecure resource '...'. This content should also be served over HTTPS.

And If you want to remove the message on the XCode's console then, please find the below steps.

1. Select Product => Scheme => Edit Scheme or use shortcut : CMD + <
2. Select the Run option from left side.
3. On Environment Variables section, add the variable OS_ACTIVITY_MODE = disable

For more information please find the below GIF representation.

Note : While debug the code in device, please unchecked this option as the NSLog statement do not show in the console.

Answer 2

May be it is printing system log. Check that once and try this

1- From Xcode menu open: Product > Scheme > Edit Scheme

2- On your Environment Variables set OS_ACTIVITY_MODE = disable
