Trying to set auto constraint on label, failing on long text

Question

I'm trying to display rows containing a thumbnail and a title.

It works great for short title strings, but for long strings, it breaks. Rather than expanding horizontally, I would prefer it to expand vertically. Checkout the screenshot below to see what happens when a long string is used. I'm using PureLayout to manage Auto Layout:

thumbnailView.autoSetDimensions(to:CGSize(width: 75, height: 75))
thumbnailView.autoPinEdge(toSuperviewEdge: .leading, withInset: kLabelHorizontalInsets)
thumbnailView.autoPinEdge(toSuperviewEdge: .top, withInset: kLabelVerticalInsets)
thumbnailView.autoPinEdge(toSuperviewEdge: .bottom, withInset: kLabelVerticalInsets, relation: .greaterThanOrEqual)

titleLabel.autoPinEdge(.leading, to: .trailing, of: thumbnailView, withOffset: kLabelHorizontalInsets, relation: .lessThanOrEqual)
titleLabel.autoPinEdge(toSuperviewEdge: .top, withInset: kLabelVerticalInsets)
titleLabel.autoPinEdge(toSuperviewEdge: .trailing, withInset: kLabelHorizontalInsets)
titleLabel.autoPinEdge(toSuperviewEdge: .bottom, withInset: kLabelVerticalInsets)

The appropriate settings on the UITextLabel are also set:

 titleLabel.lineBreakMode = .byWordWrapping
 titleLabel.numberOfLines = 0
 titleLabel.textAlignment = .left

Any suggestions are appreciated. Thanks

Found one possible solution: solution

Turns out UILabel's numberOfLines property and Auto Layout don't play along nicely.

You don't need to restrict top and bottom constraint. The UILabel will auto adjust the contentHeight. You can refer to contentHuggingPriorityForAxis: and contentCompressionResistancePriorityForAxis:. You can fix the center of label rather than the bottom and top.
