[UITableViewController init] must be used from main thread only
Hi,
I'm getting error on below line in SwiftyInspector.swift inside the lib and it's a crash @objc public static let shared = SwiftyInspector() error : [UITableViewController init] must be used from main thread only Please help
Thank You
@mukeshkvns Can you please share the stack trace? Are you getting this crash during general usage, or while specifically invoking the SwiftInspector.
If you are getting the crash when opening the inspector window, please do it on main thread.
@biocross I have the same issue. Here is a stack trace:
