## Usage

### UIKit

Since `LTMorphingLabel` is a drop-in replacement, you can use it like any `UILabel` by setting its text property, yielding the default effect (`.scale`):

```swift

var exampleLabel = LTMorphingLabel()

exampleLabel.text = "This is a test"

```

![UIKitExample1](https://github.com/jonathanwuki/LTMorphingLabel/assets/11484046/bba7138e-1ef8-4714-8792-f34349434761)

Alternatively, it can be used interactively:

```swift

var exampleLabel = LTMorphingLabel()

exampleLabel.text = "This is a test"

exampleLabel.pause()

// Call .updateProgress(progress: Float) for interactive animation

// Note: In this case, animation will stop at 45% and will not complete

//       unless called later with 100 as the `progress` float value.

exampleLabel.updateProgress(progress: 45.0)

```

The effect can be changed by setting the `morphingEffect` property:

```swift

var exampleLabel = LTMorphingLabel()

exampleLabel.text = "This is a test"

exampleLabel.morphingEffect = .burn

```

![UIKitExample2](https://github.com/jonathanwuki/LTMorphingLabel/assets/11484046/13ab83a6-7f1f-4aac-b0eb-d6172773a671)

### SwiftUI

To use `LTMorphingLabel` in SwiftUI, simply declare it and set its text, `effect`, `font`, and `textColor` properties:

```swift

public var body: some View {

    VStack {

        MorphingText(

            "This is a test",

            font: UIFont.systemFont(ofSize: 20),

            textColor: .black,

            textAlignment: .center

        )

        .frame(maxWidth: 200, maxHeight: 100)

    }

}

```

Similar to its use in UIKit, you can also specify the morphing effect manually (if you do not want to use the default `.scale` effect):

```swift

public var body: some View {

    VStack {

        MorphingText(

            "This is a test",

            effect: .burn, // Specify an alternative morphing effect with this line

            font: UIFont.systemFont(ofSize: 20),

            textColor: .black,

            textAlignment: .center

        )

        .frame(maxWidth: 200, maxHeight: 100)

    }

}

```
