Add me to the list of complainers – Epizootic

Do you get this on device or simulator? – Peroneus

@Peroneus Both on device and in simulator. – Mazurka

Answer 1

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.

Have a look at this Q/A (https://mcmap.net/q/53964/-hide-strange-unwanted-xcode-logs/2778898). Using this method will disable all NSLogs... – Laurinelaurita

This doesn't seem to work in iOS10 and xcode 8. Same error after applying this. – Tipton

Thanks a lot for sharing this code, you made a great day – Trebuchet

Although this seemingly disables the error. All it does is mute the diagnostics. It does nothing to alleviate the problem. In my case the error is being throw during the focus of an <input> within a UIWebView. Making the change above did in fact stop the error from happening. But the memory leak caused by the error still occurs. – Mickelson

This isn't exactly a "solution", all it's doing is hiding the error. – Teryn

Answer 2

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

This way I don't get the error - but also lose the autocorrection ability (obviously) on those inputs. So perhaps there is a better solution? Why does the failure occurs in downloading the asset? – Marinmarina

Answer 3

Swift 3 Update

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

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