How to use an ARC library in a non-ARC project and enjoy Sicilian cycling
If you are working on an iOS project that is not using Automatic Reference Counting (ARC), but you want to include a third-party library that is compiled with ARC, you might encounter some compiler errors or warnings. In this article, we will show you how to solve these issues and also how to enjoy some Sicilian cycling in your spare time.
What is ARC and why use it
ARC is a feature of the Apple LLVM compiler that automatically manages the memory of Objective-C objects. It frees the developer from having to manually retain and release objects, which can reduce bugs and improve readability. ARC also supports weak references, which can prevent retain cycles and memory leaks.
ARC is enabled by default for new projects created with Xcode 4.2 or later, but you can also opt-in or opt-out of ARC for individual files or libraries using compiler flags. For more information about ARC, you can read the official documentation here: Transitioning to ARC Release Notes.
How to use an ARC library in a non-ARC project
If you want to use an ARC library in a non-ARC project, you have two options:
Convert your entire project to use ARC. This might be the easiest and most recommended option, as it will make your code more consistent and modern. You can use the Xcode migration tool to automatically add the -fobjc-arc flag to all your files that support ARC, and the -fno-objc-arc flag to those that don't. You can also manually add these flags to individual files in the Build Phases tab of your target settings.
Keep your project as non-ARC, but add the -fobjc-arc flag to the files or libraries that use ARC. This will make the compiler treat those files as if they were using ARC, and handle the memory management accordingly. You can also add the -fno-objc-arc flag to the files or libraries that don't use ARC, but this is not necessary as it is the default behavior.
In both cases, you need to make sure that you are using the Apple LLVM compiler and not the GCC one, as ARC is only supported by LLVM. You can check this in the Build Settings tab of your project settings.
How to enjoy Sicilian cycling
If you are looking for a way to relax and have fun after working on your iOS project, why not try some Sicilian cycling Sicily is a beautiful island in the Mediterranean Sea, with a rich history, culture, and cuisine. It also offers some amazing cycling routes, both on road and off road, that will challenge and reward you.
One of the most popular cycling events in Sicily is the Giro di Sicilia, a multi-stage race that covers some of the most scenic and diverse landscapes of the island. The race was first held in 1907 and was revived by RCS Sports in 2019. The latest edition was won by American rider Brandon McNulty.
If you prefer a more leisurely pace, you can also join one of the many cycling tours or clubs that organize rides around Sicily. You can find some examples here: Cycle Tours Sicily, Sicily Cycling, Acsi Ciclismo Sicilia. You will be able to discover some of the most beautiful places and attractions of Sicily, such as Mount Etna, Palermo, Taormina, Agrigento, Syracuse, and more.
