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.

When I download a file using NSURLSession downloadTaskWithRequest the file ends
up in exactly the wrong volume.
Which means: I have to copy it to the right one, which, for really big files,
can take some non-trivial time.
Is it possible to advise NSURLSession which volume to use?

I have a program which talks via NSXPCConnection to a privileged helper tool.
It also can install the helper tool, using SMJobBless().
The problem: When I change the helper tool, the only way to get the new version
running is to remove:

But:
After doing SMJobBless twice, the third time I get kSMErrorInternalFailure.
Any cure for this (other than reboot)?
But anyway, this reduces the number of necessary reboots to one third.
Kind regards,

Thanks a lot! Exactly what I was trying to find.
How to translate this into Swift (current version, i.e. the one before 3.0):
UITextView *uitv = …
NSRange selectedRange = uitv.selectedRange;
NSString *textString = uitv.string;
NSString *selectedString = [ textString substringWithRange: selectedRange ];
Looks simple, but I have now tried for mor

Did in a playground:
let s = String(format: "%2s → %2s", "a", "b")
print(“formatted = \"\(s)\"")
But this prints random garbage (e.g.: formatted = “‡“S → ‡“S”) (no error
message or compiler warning).
Why?
How to create a formatted string?

I have a SuperClass with several Subclasses.
The SuperClass will never be instantiated. It just contains code common to all
subclasses.
Here an example:
I really want “onlyKnownBySubclass” to be a constant (i.e. let instead of var).
But cannot figure out how to do this.
class SuperClass

Trying to eliminate code duplication I tried to use protocol extensions.
But I ran into a rather grave problem.
This probably is “working as documented”.
But it surely it is not working like I hoped it would.
Here is a Playground example:
protocol Number
{
func aFunction() -> Int
}
exte
I have several Swift classes CclassA, ClassB), all implementing the BitField
protocol:
protocol BitField
{
init?(limit: UInt64, verbose: Int)
}
My AppDelegate Swift class has:
var a: BitField?
switch mm
{
case .A:a = ClassA(limit: maxp, verbose: verbose )
c
