Concurrent NSOperation in Swift

/// Subclasses must implement `execute()` to perform any work and call
/// `finish()` when they are done. All `NSOperation` work will be handled

Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)
# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions
# (A similar approach works for older versions too, just change the version number after DeviceSupport)

How to run Vapor with Docker in Heroku

How to run Vapor with Docker in Heroku

In this tutorial you'll learn how to run a Vapor server in a Docker container on Heroku.

Recently, Heroku added the ability to run Docker images on their Runtime. You can use this system instead of the traditional buildpack-based system for various reasons, mainly for having more control over the environment your server will run on.

Prerequisites

To complete this tutorial, you'll need:
