How do I auto size a UIScrollView to fit its content
...
for (UIView *view in self.scrollView.subviews) {
contentRect = CGRectUnion(contentRect, view.frame);
}
self.scrollView.contentSize = contentRect.size;
Swift
let contentRect: CGRect = scrollView.subviews.reduce(into: .zero) { rect, view in
rect = rect.union(view.frame)
}

Should I add .vcxproj.filter files to source control?
...st found that if you use Git you can mark .filter files to be treated as a union for merging to make it simpler. Just add the line:
*.vcxproj.filters merge=union
to your .gitattributes file.
See Using .gitattributes to avoid merge conflicts for more details.

Javascript fuzzy search that makes sense

Compare two List objects for equality, ignoring order [duplicate]
...here duplicates in either are ignored), you can use:
// check that [(A-B) Union (B-A)] is empty
var areEquivalent = !list1.Except(list2).Union( list2.Except(list1) ).Any();
Using the set operations (Intersect, Union, Except) is more efficient than using methods like Contains. In my opinion, it al...
How to find the kth smallest element in the union of two sorted arrays?
...as length respectively. We need to find the k-th smallest element from the union of those two arrays. Here we reasonably assume that (k > 0 && k <= size1 + size2), which implies that A1 and A2 can't be both empty.
First, let's approach this question with a slow O(k) algorithm. The met...
What are the most common naming conventions in C?
...function names, hardly ever do you see camel case in C;
structs, typedefs, unions, members (of unions and structs) and enum values typically are in lower case (in my experience) rather than the C++/Java/C#/etc convention of making the first letter a capital but I guess it's possible in C too.
C++ ...
What's wrong with nullable columns in composite primary keys?
...ing accepted.
[* NOTE: It is possible to create a custom type that is the union of integers and a "bottom" type that would semantically mean "empty" as opposed to "unknown". Unfortunately this introduces a bit of complexity in comparison operations and usually being truly type correct isn't worth t...
Iterate two Lists or Arrays with one ForEach statement in C#

You can use Union or Concat, the former removes duplicates, the later doesn't
foreach (var item in List1.Union(List1))

//TODO: Real code goes here
}
foreach (var item in List1.Concat(List1))
{
//TODO: Real code goes here
}

13. Over-reliance on UNION ALL and particularly UNION constructs
A UNION in SQL terms merely concatenates congruent data sets, meaning they have the same type and number of columns. The difference between them is that UNION ALL is a simple conc...
