A QuickLook plugin on macOS 10.14 has several constraints to satisfy. If one of the limits is exceeded, the plugin will immediately be killed and no preview will be visible. Having such restrictions makes sense but they appear to be undocumented. This article addresses the lack of information about these constraints.
In a previous article, I reverse-engineered the .car file format used to store the compiled assets of an Asset Catalog. I also demonstrated how to create a tool to manually parse such files. While this tool can extract a lot of information, it is cumbersome to use if you want to quickly see all the assets contained in a car file.
An Asset Catalog is an important piece of any iOS, tvOS, watchOS and macOS application. It lets you organize and manage the different assets used by an app, such as images, sprites, textures, ARKit resources, colors and data.
Two years ago I measured Apple’s use of Swift in iOS 10.1 and last year I counted how many applications were using Swift in iOS 11.1.
This year I’m analyzing iOS 12, released by Apple this month.
macOS 10.13 contains a built-in VPN client that natively supports L2TP over IPSec as well as IKEv2.
In this post I describe some parts of the internal architecture of the macOS VPN client. This information will be used in a following article to build an application that replicates some functionalities of the VPN status in the menu bar. This application will also allow to auto connect to an IKEv2 VPN service, something that is currently not possible on macOS.
A year ago I analyzed how many built-in apps in iOS 10.1 and macOS 10.12 were using Swift: Apple’s use of Swift in iOS 10.1 and macOS 10.12.
How many built-in apps are using Swift in iOS 11.1 and macOS 10.13.1? Let’s find it out!
