Glance
Glance is lightweight library that allows you debug view hierarchy right from you mobile device or simulator
Installation
Swift Package Manager
dependencies: [
.package(url: "https://github.com/nikitabelopotapov/Glance.git", .upToNextMajor(from: "0.0.1"))
]
Usage
Suggested use-case is to attach Glance to shake gesture in UIWindow extension
import Glance
extension UIWindow {
open override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
super.motionEnded(motion, with: event)
if motion == .motionShake {
Glance.main.debug(view: self)
}
}
}
Custom views
In order you have any custom or not supported view (such as view that drows in content in CGContext), you can provide custom.
final class CustomLayoutProvider: LayoutProvidable {
var layoutMapper: LayoutMappable?
func provide(for view: UIView, depth: inout Float, masterView: UIView?) -> [LayoutSnapshot] {
return [LayoutSnapshot(image: UIImage(), depth: 1, frame: .zero, view: view)]
}
}
And then add it to Glance layout providers
@main
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
Glance.main.addLayoutProvider(provider: CustomLayoutProvider(), viewClass: MyCustomClass.Type)
return true
}
}
View properties (Beta)
By tapping any view in Glance main screen you can inspect view properties.
Now this feature is not fully implemented.
