Grand Central Dispatch, or GCD for short, is a low-level C APIs for managing concurrent tasks. It helps us improve our app performance by executing a block of code in reasonable threads, like perform computationally expensive tasks in the background. GCD provides several options for running tasks such as synchronously, asynchronously, after a certain delay, etc.
In this post I will explain more details about GCD and how it works, also provide some interesting points when we work with GCD. Let’s start.

Swift Summit Conference 2017 was held at the Palace Of Fine Arts, San Francisco, which is one of ten palaces at the heart of the Panama-Pacific Exhibition. At the conference, Swift developers from around the world shared new knowledge, tools and ideas on iOS platform and Swift language.

The Core Bluetooth (CB) framework allows iOS and MacOS apps communicate with BLE devices. Your apps can discover, explore, and control the BLE devices, such as heart rate monitors, trackers or hybrid watches.

CocoaPods is a dependency manager for Swift and Objective-C projects. This tool not only allows us to easily integrate those dependencies but also allows us to create our own libraries. In this post I’m going to guide you how to create a private library and distribute it to your private team without publishing the library.
