Layout constraint problem, Xcode 11 and iOS 13

[kevint727]

Using the latest Xcode 11 beta and its' accompanying simulators (and a physical device) running iOS 13, when trying to type in a UITextField, I get the following layout constraint error. This happens for any TextField on any of my views. I am using the latest version of IQKeyboardManager (6.4.1). I have never seen this before and I have been using the wonderful IQKeyboardManager for quite some time. I realize this is on beta software but just want to make sure this will not be an issue going forward as I've had iPhones (especially older ones) freeze up before in the wild because of layout constraint problems.

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

This is still happening in the Xcode 11 GM seed and with using 6.4.2.

[dhomes]

same with xcode11 gm & 6.4.2

No i have put Mapbox with IQmanager and when ever Mapbox opens the y axis offset of IQkeyboard manger changes and toolbar will not able to show. if any one have any soultion then it will be more appriciate

[tosbaha]

You can fix this issue by adding a non empty frame for UIToolbar in library code. I am not familiar with how this library initializes the UIToolbar. Check the source code make the changes according to below example.

So instead of doing

let toolbard = UIToolbar()

Do it like below

let toolbard =  UIToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 35))

[mobileappdeveloper2019]

Dear @tosbaha

Thanks for reply, actually when ever Mapbox opens then keyboradFrameOffset changes from 0 to -260 and it will create problem to IQKeyboardManager toolbar offset. no need to change toolbar frame, I need to know what can I change in Mapbox so that it will fix in IQKeyboard.

@mobileappdeveloper2019 I am sorry I don't use this library at all. I just commented because I had similar issue on iOS 13. I am not sure but you may try to change

let newToolbar = IQToolbar()

line with

let newToolbar = IQToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 35))

Good luck.

I had the same issue and I was able to fix it by following this.
