THE PROBLEM

After updating to macOS Big Sur beta you might encounter issues when using Ruby Bundler to manage Ruby gems in your project - in our case to install CocoaPods and Fastlane for iOS development.

Ignoring json-2.2.0 because its extensions are not built. Try: gem pristine json --version 2.2.0

...

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse
