Function to print the memory usage of whatever you pass in - struct/class/function/variable/constant, etc

ViewController.swift

class ViewController: UIViewController {

    override func viewDidLoad() {
        self.checkMemoryUsage(self.tableView) }

func checkMemoryUsage<R>(_ thingToCheck: R, name: String = #function) {
        // You can pass in almost anything - a variable/constant/struct/class/function etc.
        let size = MemoryLayout.size(ofValue: thingToCheck)
        let stride = MemoryLayout.stride(ofValue: thingToCheck)
        let alignment = MemoryLayout.alignment(ofValue: thingToCheck)
        print("\(name).size: \(size)")
        print("\(#function)).stride: \(stride)")
        print("\(type(of: thingToCheck)).alignment: \(alignment)") } }
