I'm using xcode 8 version with ios 10. If, I use project in ios 9.3 its works fine but when same project I used in ios 10 error message appears Unable to copy asset information...

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.

Swift 3 Update

@guest answer fixes the problem. But incase if you are creating the UITextViewprogrammatically.

textView.spellCheckingType = .no
textView.autocorrectionType = .no
