 Selection indicator can be customized by passing an instance of `SegmentioIndicatorOptions`:
 
 ```swift
 SegmentioIndicatorOptions(
-	type: .Bottom,
-	ratio: 1,
-	height: 5,
-	color: UIColor.orangeColor()
+            type: .bottom,
+            ratio: 1,
+            height: 5,
+            color: .orange
 )
 ```
 
 Horizontal borders can be customized by passing an instance of `SegmentioHorizontalSeparatorOptions`:
 
 ```swift
 SegmentioHorizontalSeparatorOptions(
-	type: SegmentioHorizontalSeparatorType.TopAndBottom, // Top, Bottom, TopAndBottom
-	height: 1,
-	color: UIColor.grayColor()
+            type: SegmentioHorizontalSeparatorType.topAndBottom, // Top, Bottom, TopAndBottom
+            height: 1,
+            color: .gray
 )
 ```
 
 Separators between segments can be customized by passing an instance of  `SegmentioVerticalSeparatorOptions`:
 
 ```swift
 SegmentioVerticalSeparatorOptions(
-	ratio: 0.6 // from 0.1 to 1
-	color: UIColor.grayColor()
+            ratio: 0.6, // from 0.1 to 1
+            color: .gray
 )
 ```
 
 In order to set `SegmentioStates` you need to create a tuple of `SegmentioState` instances:
 
 ```swift
 SegmentioStates(
-	defaultState: segmentioState(
-		backgroundColor: UIColor.clearColor(),
-		titleFont: UIFont.systemFontOfSize(UIFont.smallSystemFontSize()),
-		titleTextColor: UIColor.blackColor()
-	),
-	selectState: segmentioState(
-		backgroundColor: UIColor.orangeColor(),
-		titleFont: UIFont.systemFontOfSize(UIFont.smallSystemFontSize()),
-		titleTextColor: UIColor.whiteColor()
-	),
-	highlightedState: segmentioState(
-		backgroundColor: UIColor.lightGrayColor().colorWithAlphaComponent(0.6),
-		titleFont: UIFont.boldSystemFontOfSize(UIFont.smallSystemFontSize()),
-		titleTextColor: UIColor.blackColor()
-	)
+            defaultState: SegmentioState(
+                backgroundColor: .clear,
+                titleFont: UIFont.systemFont(ofSize: UIFont.smallSystemFontSize),
+                titleTextColor: .black
+            ),
+            selectedState: SegmentioState(
+                backgroundColor: .orange,
+                titleFont: UIFont.systemFont(ofSize: UIFont.smallSystemFontSize),
+                titleTextColor: .white
+            ),
