Master-Detail app for iPhone
Master has a TableView with words and a SearchField.
DetailView has info about selected word.
Hitting the Back-Button in the DetailView shows the MasterView and then (after
what feels like a second) the Keyboard slides up.
This is not what I want.

NSInteger modValueS = rawValue;

An UITableViewController with an UISearchController in iOS 8.3
When I click in the SearchBar the following dance happens:
Keyboard comes;
Keyboard goes away;
Background becomes gray;
Keyboard comes again and now stays.
This is sort of difficult to see in the Simulator because it happens too

I have a UITableView with a UISearchController.
One types into the search field and the table is filled with appropriate
entries.
But only a small part of the table is visible, the rest is obscured by the
keyboard.
When one stops typing and starts scrolling the table it would be nice if the

While my iPhone can use the “DoSomethingAndGoBackToMasterView” button fine,
the same button does nothing for iPad.
Of course iPad does not need an unwinding segue - both master and detail view
are always visible (at least in landscape orientation). But the “DoSomething”
part is still needed.

Using the Xcode template: iOS - Master-Detail, the Detail view has (in the top
left corner) a Back-Button, which works fine.
Now I added another UIBarButtonItem called: “Do something and go back”
connected to some IBAction in DetailViewController.
But how to make it go back to the MasterView?
Controller property.
But then: how to get the UIStoryboardPopoverSegue ?

No dictionary will ever contain "yellow colour". Every dictionary will contain

I searched the Swift book for "thread" and found nothing.
A quicksort algorithm works like:
quicksort(array)
{
partition(array)
quicksort( left side)
quicksort( right side)
}
On Obj-C I just did:
quicksort(array)
{
partition(array)
dispatch_apply( 2, queu

Swift has an Unchecked option, which is still about 25 % slower than Obj-C.

Well, the OBj-C sort gets a Swift array and treats it as as a C-array of
UInt32. Same as the Swift version.

Not really. More like learning.

This works:
private func shiftArray( inout arr: [UInt32], lowerIndex: UInt, upperIndex:
UInt )
{
// move: arr[ lowerIndex ..< upperIndex ] to: arr[ lowerIndex + 1
... upperIndex ]
let av = arr[ Int(upperIndex) ]
for v

How to translate into Swift:
- (void)myFunctionWithClass: (Class)someClass
{
for(...)
{
p = ...
if ( p is not special ) continue;
id aClass = [[ someClass alloc] initWithParameter:
p ];
... do something with aClass
