Error in iOS 10 : Unable to copy asset information from https://mesu.apple.com/assets/ for asset type

Setting OS_ACTIVITY_MODE = disable doesn't resolve the issue but only turn off the logs

To fix the issue:

1- In storyboard select the TextView

2- From Xcode attributes inspector set:

Correction = No

Spell Checking = No

3- Fixed

The problem appears to happen because of failure to download assets for spell checking from: http://mesu.apple.com/assets/com_apple_MobileAsset_TextInput_SpellChecker/com_apple_MobileAsset_TextInput_SpellChecker.xml

Hope this helps

I have end up with below solution. Follow the steps.

• Set the the Environment Variable in Edit Scheme.
• Restart the xcode.
• Clean & build xcode.

& than work perfectly on my side.
