SwiftOverlays is a Swift GUI library for displaying various popups and notifications.

SwiftOverlays provides several ways to notify user:

• Wait overlay: a simple overlay with activity indicator

• Wait overlay with text

• Overlay with text only
• Overlay with image and text (can be used with PPSwiftGifs to show custom animated GIF instead of UIActivityIndicatorView)
• All of the above with blocking any user interaction
• Notification on top of the status bar, similar to native iOS local/push notifications

Just clone and add SwiftOverlays.swift to your project.

• > Cartfile
• nano Cartfile
• put github "peterprokop/SwiftOverlays" ~> 5.0.1 into Cartfile
• Save it: ctrl-x, y, enter
• Run carthage update
• Copy SwiftOverlays.framework from Carthage/Build/iOS to your project
• Make sure that SwiftOverlays is added in Embedded Binaries section of your target (or else you will get dyld library not loaded referenced from ... reason image not found error)
• Add import SwiftOverlays on top of your view controller's code

• Make sure that you use latest stable Cocoapods version: pod --version
• If not, update it: sudo gem install cocoapods
• pod init in you project root dir
• nano Podfile, add:

pod 'SwiftOverlays', '~> 5.0.1'
use_frameworks! 

• Save it: ctrl-x, y, enter
• pod update
• Open generated .xcworkspace
• Don't forget to import SwiftOverlays: import SwiftOverlays!

• iOS 10.0+
• Xcode 10.0+
• Swift 4.2 (if you need older swift version, see swift-3.0 and others)

If you're using CocoaPods, import the library with import SwiftOverlays

You can use UIViewController convenience methods provided by library:

// In your view controller:

// Wait overlay
self.showWaitOverlay()

// Wait overlay with text
let text = "Please wait..."
self.showWaitOverlayWithText(text)

// Overlay with text only
let text = "This is a text-only overlay...\n...spanning several lines"
self.showTextOverlay(text)

// Remove everything
self.removeAllOverlays()

// Notification on top of the status bar
UIViewController.showOnTopOfStatusBar(annoyingNotificationView!, duration: 5)

// Block user interaction
SwiftOverlays.showBlockingWaitOverlayWithText("This is blocking overlay!")

// Don't forget to unblock!
SwiftOverlays.removeAllBlockingOverlays()

You can't use SwiftOverlays convenience methods directly with UITableViewController - because its view is, well, an UITableView, and overlay will be scrolled along with it.

Instead I suggest using UIViewController instead of UITableViewController and adding UITableView as a subview. (the same applies to UICollectionViewController)

If for some reason you can't use UIViewController, you can do something like:

if let superview = self.view.superview {
  SwiftOverlays.showCenteredWaitOverlayWithText(superview, text: "Please wait...")
  SwiftOverlays.removeAllOverlaysFromView(superview)
}

(but in that case overlay will be added to the superview, and you should obviously do that only if superview is available - for example in viewDidAppear method of your controller.).
