It’s very easy if you just want to display or hidden the indicator. This code will solve that.

	UIApplication.shared.isNetworkActivityIndicatorVisible = true/false

But allways has multiple requests at your apps. Then how can we know when need display or hidden it. So, here it is. We can create a managing class to hold it. The idea is you just need call when a request start/stop, then the managing class will count and display/hidden the indicator.

Here is the code:

class NetworkActivityIndicatorManager: NSObject {
    
    public static let shared = NetworkActivityIndicatorManager()
    
    // MARK: - Property
    
    private var count: Int = 0
    private let application = UIApplication.shared
    
    // MARK: - Lifecycle
    
    private override init() { }
    
    // MARK: - Public Methods
    
    public func startActivity() {
        DispatchQueue(label: "com.ilukes.naim").sync {
            if self.application.isStatusBarHidden {
                return
            }
            if !self.application.isNetworkActivityIndicatorVisible {
                self.application.isNetworkActivityIndicatorVisible = true
                self.count = 0
            }
            
            self.count += 1
        }
    }
    
    public func stopActivity() {
        DispatchQueue(label: "com.ilukes.naim").sync {
            if self.application.isStatusBarHidden {
                return
            }
            
            self.count -= 1
            
            if self.count <= 0 {
                self.application.isNetworkActivityIndicatorVisible = false
                self.count = 0
            }
        }
    }
}
