Swift Code that check if the debugger is attached to your iOS Device (App runs in XCode) while running your app

IsDebuggerAttached.swift

    #if DEV
   fileprivate func isDebuggerAttached() -> Bool {
        var info = kinfo_proc()
        var mib : [Int32] = [CTL_KERN, KERN_PROC, KERN_PROC_PID, getpid()]
        var size = MemoryLayout<kinfo_proc>.stride
        let junk = sysctl(&mib, UInt32(mib.count), &info, &size, nil, 0)
        assert(junk == 0, "sysctl failed")
        return (info.kp_proc.p_flag & P_TRACED) != 0
    }
    #endif
