How to detect that the app is running on a jailbroken device? [duplicate]

Answer 1

Based off of @karim's answer heres a slightly modified swift version:

func hasJailbreak() -> Bool {
    #if arch(i386) || arch(x86_64)
        println("Simulator")
        return false    
    #else
        var fileManager = NSFileManager.defaultManager()
        if(fileManager.fileExistsAtPath("/private/var/lib/apt")) {
            println("Jailbroken Device")
            return true
        } else {
            println("Clean Device")
            return false
        }
    #endif
}
