Unable to simultaneously satisfy constraints.

[NinjaIshere]

I have attached image of my storyboard and it is empty i have commented out most of my code to only show the MK Card

When i add this code to the MK Card I get constraint issues //material Kit Card card.detailLabel = UILabel() card.detailLabel?.textAlignment = .Center card.detailLabel?.font = UIFont(name:"Arial", size: 45) view.backgroundColor = MaterialTheme.grey.darken1

(when i remove the line of code above this issue is gone, could it be the size of the font?)

@NinjaIshere Yes it could be :) :+1: good catch will check this out in the am and update you

[daniel-jonathan]

@NinjaIshere What is the size of the container that the MK card is going within?

[NinjaIshere]

@danieldahan -

    // card layout
    view.addSubview(card)
    view.addConstraints(Layout.constraint("V:|-(pad)-[child]", options: nil, metrics: ["pad": 60], views: ["child": card]))
    Layout.size(view, child: card, width: 380, height: 310)
    card.backgroundColor = MaterialTheme.grey.darken1

[daniel-jonathan]

If you could copy and paste the entire error output that would be great. But from your code, you have two vertical constraints, and really only need one.

Your height doesn't need to be specified in the second Layout.size statement.

You should try:

view.addConstraints(Layout.constraint("V:|-(pad)-[child(310)]", options: [], metrics: ["pad": 60], views: ["child": card])) Layout.width(view, child: card, width: 380)

Also, where are you getting the width 380 from? Are you trying to set it to the bounds of the view, as in, entirely across the screen. You would be better off doing:

Layout.expandToParentHorizontally(view, child: card)

[NinjaIshere]

@danieldahan - I will try what you mentioned above, until then here is the whole error code below, but i have added back the other buttons so there will be lots more constraint issues in the logs. I will post back if the changes above fixed the issue.

So from the constraint issues, I can tell that you are doing quite a bit to the view. Would you be able to add the entire block of code that generates the view and all manipulations you are doing to it. Also, please use dev and pull the latest, which will help determine if you are experiencing a legacy issue.

Thanks!

[NinjaIshere]

Those extra constraints issues are from the UISlider and the UILabel (sliderValue) which are being added using the storyboard, but they have no constraints added to them, i have tried completely removing everything and just leaving the "card" and i still get the same type of errors.

@NinjaIshere Did you try the latest dev with the code you have?

[NinjaIshere]

@danieldahan - ya i did it was up to date when i did git pull

[daniel-jonathan]

You should update again.

BasicCard doesn’t exist in the latest development branch. It is BasicCardView.

@danieldahan - hmm weird, i was pulling from wrong directory, I switched over and now i cant build MK, it has like 149 errors, probably something im doing, i might need to recreate the my workspace.

[daniel-jonathan]

Okay, I just made a huge update to MK 1.14.0

Try that out :)
