# HidingViews

This is a custom ViewModifier, `.isHidden(_:)`. It allows a View to be hidden, controlled by a boolean property/value.

This project is an example of how to use it. Use it like so:

```swift

Text("Hello World!")

    .isHidden(true)

```

        

Or:

```swift

Text("Label")

    .isHidden(true, remove: true)

```

        

`@State` can come in very useful for this situation to actively change whether a view is hidden, for example controlled by a `Toggle`.

---

        

If you are just interested in the code for it to create the modifier, here it is:

```swift

import SwiftUI

extension View {

    

    /// Hide or show the view based on a boolean value.

    ///

    /// Example for visibility:

    ///

    ///     Text("Label")

    ///         .isHidden(true)

    ///

    /// Example for complete removal:

    ///

    ///     Text("Label")

    ///         .isHidden(true, remove: true)

    ///

    /// - Parameters:

    ///   - hidden: Set to `false` to show the view. Set to `true` to hide the view.

    ///   - remove: Boolean value indicating whether or not to remove the view.

    @ViewBuilder func isHidden(_ hidden: Bool, remove: Bool = false) -> some View {

        if hidden {

            if !remove {

                self.hidden()

            }

        } else {

            self

        }

    }

}

```
