I have been trying to get my progress view to update, but most of the questions have been about using progress view as a timer. Instead, I am running a for loop a couple thousand times and it takes a little why. I want the use to know how far along the method is, so I've implemented a progress view like this (there is a bunch of other stuff in the for loop but I don't think it is necessary to answer my question):

for i in 0..<2429 {
        var progress = Double(i) / Double(2430)
        print(progress)
        seasonProgress.setProgress(Float(progress), animated: false)
        seasonProgress.reloadInputViews()   
}

When I print progress is it updating with every loop, but the progress view (name seasonProgress) only updates after the for loop is complete. How do I get it to upload while the for loop is going? Thanks in advance!!!

No need for `reloadInputViews()`. make sure you run it on MainThread – Tal Cohen Oct 28 '18 at 17:26
Your loop is blocking the main queue until it completes. Do not block the main queue as you perform some long running process. – rmaddy Oct 28 '18 at 17:41
I'm sorta new to this, what does it mean to block the main queue? and how do I avoid that? – Stefan Walzer-Goldfeld Oct 29 '18 at 00:46
