Error on IOS 13

[LuisCabCac]

Hello, i find a error on IOS13.

I´m using the autosuggest calling some API and assigning into a viewModel the new Items. This funtionallity was running OK, but on IOS 13 i have this error, i´m update to 1.0.0 version but the error continue, can´t you help me?.

Unable to activate constraint with anchors because they have no common ancestor. Does the constraint or its anchors reference items in different view hierarchies? That's illegal

Thanks for all.

AFAIK I fixed that specific bug in 1.0.0, but I wouldn't rule out there's more. Could you provide a simple app that reproduces the problem? There's really nothing above to go on, but a repro makes it easy/quick for me to fix (I've tested on both 12 and 13 and works ok for me in the scenarios I've tested)

Hi, i´m try to reproduce in a simple application, and it´s complicted, on same code it´s running, I think that depends of the view., the full message is this.

Hello, i see why the component break, in the main project if change this line, the project run.

I think that in the component, try to modify the mainpage always ?

Sorry this still isn't enough to go on. From the error I know where it's throwing and that happens because it's hit too soon. What I don't know is why, and without a repro any fix would be pure guesswork

Thanks for all, i change the mode that open the View with the component and the error don´t continue. I think that try to put item in diferent view, it is when show the component in the four View, if i change the open mode in some of the 4 views the error don´t show it.

Close this Issue, if i have some time and reproduce the error in a test App, i´ll open other issue and sent you the error.
