Memory Issue #90

Open Jhtang opened 7 years ago

Jhtang commented 7 years ago

Hi Adam, I have been using your wonderful SignalR Client for Mac to develop the Alert application running on Mac. For somehow, my program starts to have a memory leak issue after running it for a while. So far I still could not find out where did it come from even though I use the Xcode Leak tool.

Your advice is greatly appreciated.

Sincerely, Joseph

Are you using UIWebView or WKWebView?

I meant did you configure SwiftR to use WKWebView behind the scenes. It always uses a hidden web view. You would have code like this if you're using WKWebView:

// Client
let connection = SignalR("https://swiftr.azurewebsites.net")
connection.useWKWebView = true // <-- See here

The reason I ask is: UIWebView is known to leak memory. WKWebView is the better choice for SwiftR, but does have some limitations. See the README for more info there.

Thank you very much for your advice. I turned on useWKWebView for now, and I will test it to see if it still has the memory leak issue.

Sincerely, Joseph

I tried it on my iMac, it seems working fine. However, my colleague tried the app on his iMac and he got a lot of instances of app web content in the Activity Monitor. The app occupied a few GB memory.
