Question 1

How do I use MMLanScan in a Swift project?

Accepted Answer

After installing via CocoaPods or manual drag-and-drop, create a bridging header to import MMLANScanner files, initialize it with a delegate, and implement delegate methods like lanScanDidFindNewDevice to handle scan results. The README provides explicit Swift code snippets for setup.

Question 2

Does MMLanScan work on iOS 16 or later?

Accepted Answer

MMLanScan can still scan for IP addresses and hostnames on newer iOS versions, but MAC address and brand retrieval are broken on iOS 11+, so it won't provide complete device details. You'll need alternative methods for MAC info on modern devices.

Question 3

How accurate is MMLanScan compared to command-line network tools?

Accepted Answer

It's designed to detect non-pinging hosts for better accuracy than ping-only scanners, but due to iOS restrictions on ARP table access, it's less reliable for MAC addresses on newer OS versions compared to desktop tools.

Question 4

Can I update the MAC address to brand mappings in MMLanScan?

Accepted Answer

Yes, you can update the OUI plist file for brand identification, but this requires manual editing and regex parsing as noted in the README's TODO, which can be cumbersome for maintaining up-to-date vendor data.

Question 5

MMLanScan vs using native iOS networking APIs for scanning?

Accepted Answer

MMLanScan simplifies scanning by wrapping Apple's SimplePing into a high-level API, but for full control or iOS 11+ compatibility, native APIs might be better, especially since MMLanScan's MAC features are deprecated on modern iOS.

Question 6

How to scan networks outside the local subnet with MMLanScan?

Accepted Answer

MMLanScan supports any subnet configuration, so you can specify different IP ranges in your scan setup. However, scanning remote networks may be limited by iOS sandboxing and network permissions, requiring proper app entitlements.
