I wanted to know whether we can call fork() and system() function within an iOS application? Whether apple review rejects the application.
In order to identify whether the device is jailbroken. I wanted to include the following code in application

Code Block let pid = fork()
if(!pid)
{
   return true
}
else if(pid >= 0)
{
   return false
}
OR
let system= system()
if(system == 1)
{
   return true
}
else if(system == 0)
{
   return false
}

I strongly recommend against this. Even if you ignore the App Store complications, checks like this always have binary compatibility impact, resulting in either false negatives or, worse yet, false positives.

A better option here is the DeviceCheck framework. See Establishing Your App’s Integrity.
