And you are sure that the textField is resigned and this is not the one from Xcode Simulator Known Issue explained in README. Correct?

This happens in the demo app as well as in my own. I'm not sure if the demo app does resign it. I though the known issue is talking about black toolbar, not this black space. I'll try to add resignation to see.

Are you sure this issue is reproducible with Real iOS devices?

Yes, I found it on my iPhone 6 with iOS 9.3.

Ok, then could you please provide me a video?

I'll try.

Thank You! I'll try to take a look at it tomorrow.

@hackiftekhar Thanks!

Do you think it is related to the known bug?

If this is reproducible with real device then it's not from the known but and it's new bug. I can comment something after looking the video.

I checked and I found that it's a bug. We need to fix it.

I checked the code and I found that IQKeyboardManager is doing correct frame changes, but iOS reset the ViewController's frame in the middle somewhere. I tried to capture frame changes using observers. But observer also doesn't capture the frame change made by iOS (with pop swipe gesture). I'm sure it's related to iOS, but still we need to do some workaround to avoid this issue. I feels that it's hard to fix because all the keyboard and textfield notifications are coming in exact order like a normal textField does with begin/resign responder. I don't have any clues by which I could identify something to fix this situation.

i am still facing this issue any clues to avoid this?

which version you are using @Homeshchopra94, can you please upload a demo because I'm unable to reproduce this issue anymore.
