Usage of ToLayoutConstraints

This version of AddConstraints permits the use of both simple and advanced constraints in the same call. If you remove ToLayoutConstraints it will not work anymore.

Advanced constraints methods use more than one Constraint object to achieve the result.

        public static void AddConstraints(this UIView view, params object[] fluentLayouts)
        {
            view.AddConstraints((fluentLayouts
                .Where(fluent => fluent != null)
                .OfType<FluentLayout>()
                .SelectMany(fluent => fluent.ToLayoutConstraints())
                ).Concat(fluentLayouts
                    .OfType<IEnumerable<FluentLayout>>()
                    .SelectMany(fluent => fluent.SelectMany(fluent2 => fluent2.ToLayoutConstraints()))
                ).ToArray());
        }


        public static IEnumerable<FluentLayout> WithSameRectOf(this UIView view, UIView parent, nfloat? margin = null)
        {
            return
                view.FullWidthOf(parent, margin)
                    .Concat(view.FullHeightOf(parent, margin))
                    .Concat(view.AtTopLeftOf(parent, margin));
        }

Sample usage:

ContentView.AddConstraints(
                title.AtLeftOf(ContentView, 2.5f),
                title.AtTopOf(ContentView, ItemSize.Width + 2.5f),
                image.WithSameRectOf(imageSvg)
                );

Without this extension methods, WithSameRectOf can not be used.

I’d suggest, instead of adding non-constructive comments, that you made a PR so your own changes could be merged in upstream. If you don’t want to do that keep using your own stuff.

It is dormant until you really remove the code. If you remove it i will wake it up fast!!!
