Make sure you have Xcode installed. If not, simply search and download from AppStore. IINA will always update to the latest Swift version as soon as possible, so you must build it with the latest Xcode. Please note that this usually requires the latest macOS version, too.

To clone the project, you need:

• Have git installed:

  brew install git
  

• Or Github Desktop if you are not familiar with command line.

Make sure you have CocoaPods installed:

sudo gem install cocoapods
