Best way to make a little piece of data persistent?

I need to make a few small pieces of data (an integer, a string, ...) persistent across different invocations of my screen saver. That is, when the screen saver is about to quit, I need to save it, when it gets invoked the next time, I need to load it again. What is the recommended (and easiest?)

Have tool tips displayed longer?

Is there a way to adjust the duration how long the tool tips of my GUI are displayed during runtime? (I'd like macOS to display them longer than the default.) Best regards, Gabriel. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please

Multipeer between macOS Sierra and iOS 10

I emailed the list yesterday about getting communication going between an iOS application and a macOS one. I coded it up this morning and it works quite well. However the consoles are filled with Errors eventhough things are connected and send data back and forth. Things like: [ViceroyTrace] [ICE]

NSSecureTextField and Umlaute and the likes

I'm developing a password manager that uses an NSSecureTextField for the user to type a password. The Problem is, that on some keyboard layout keys like ñ have to be typed using multiple keys or can be inserted via a hold on the key and then selecting the special one via the popup. This works on

Implementing own text prediction on UITextField

Currently when we type on a text field it shows text prediction over keyboard on a bar, is there any way to populate the same with say a dictionary, or a plist, etc. Basically populating it using own data source rather than system data source. Any ideas guys? Thanks in advance. __

URL.setResourceValues() in Swift 3

I don't know if Xcode 8 just has more bugs showing headers, or what. But I'm trying to make this call, as documented in the docs: let _ = fm.createIntermediateDirectories(destURL) try destURL.setResourceValues([. isExcludedFromBackup : true]) But I get "Value of type 'Bool' does not conform to

Re: Mystery Threads

My thoughts are general, not specific to Mac OS... The idea that the best performance comes from threads = #CPUs is attractive, but will work only if the threads do not sleep and do not interfere with each other. A classic example is dividing up a complex calculation that runs without touching the

Mystery Threads

I have a big array (like a few GB) which is operated upon by some functions. As these functions act purely local, an obvious idea is: - (void)someFunction { nbrOfThreads = ... sizeOfBigArray = ... a few GB stride = sizeOfBigArray / nbrOfThreads dispatch_ap
