How do you use posix_spawn to replace the deprecated 'system' to launch opendiff in Objective-C?

Question

This line of code:

system(\"/Applications/Xcode.app/Contents/Developer/usr/bin/opendiff /Users/LukeSkywalker/Documents/doc1.rtf /Users/LukeSkywalker/Documents/do         


        

Answer 1

Swift 3, Xcode 8.3.1

func system(_ command: String) {
    var args = command.components(separatedBy: " ")
    let path = args.first
    args.remove(at: 0)

    let task = Process()
    task.launchPath = path
    task.arguments = args
    task.launch()
    task.waitUntilExit()
}
