NSWindow min and max size (Swift 4)
You can force the views to keep a inferred min and max width/height by using AutoLayout, but what if you’re working with several views simultaneously? Wouldn’t it be simpler to have a window min and max width/height? Just add the following in your NSWindowController: override func windowDidLoad() { super.windowDidLoad() …
NSImageView Aspect Fill
Setting an image to use AspectFill in iOS is trivial, you can set it by code or directly in storyboard. But how do you do it in macOS? In Cocoa/App Kit there is no property for that, you may scale it , but there is no option for AspectFill (or AspectFit for that matter). So, …

Denarius 1.6 & the slippery bug

Blogging about developing an app: Denarius
Roughly two years ago I started blogging about the challenges of developing a new Mac app. I decided to do so after reading Brent Simmons great series on Vesper development.

Simple Animations on macOS (Swift 3)

Synchronizing Main and Background Core Data Threads (Swift 3)
Let’s say we have two different managedObjectContext (with one persistentStoreCoordinator). The first one is used across the app for most quick fetches: var mainManagedObjectContext = NSManagedObjectContext(concurrencyType: NSManagedObjectContextConcurrencyType.mainQueueConcurrencyType) mainManagedObjectContext.persistentStoreCoordinator = coordinator And the second, running in the background, for the queries that take a long time: var backgroundManagedObjectContext = NSManagedObjectContext(concurrencyType: …
