I have a wireless AP+switch which I configured years ago, before moving, and haven't used for a while. Now I want to reconfigure it for my new network, but have no idea what I set as its IP address(It was probably something 192.168.xx.yy). What is the best way for discovering its IP? A script to spam the whole address space?

If you can't remember the IP/subnet, you're likely not going to remember the security/authentication settings and passphrase either, so I'd just reset it to factory default. There's likely a reset button on the back and some combination of power cycle/holding it down that you can find by googling the AP model for a manual.

The nmap command can quickly ping any address range. For example,

nmap -sP 192.168.0.0-254

By "spam", do you mean "scan"? If so, then yes that's one way to do it. You can use something like Angry IP Scanner to scan your subnet for devices with ip addresses and then try them one by one.

Can't you simply connect your PC to the AP/Switch with a direct cable and obtain the IP from your IP settings of this PC (Gateway)?
