IOS 10 Wide Color: Do I need to be concerned?
<p>The <a href="https://developer.apple.com/library/prerelease/content/releasenotes/General/WhatsNewIniOS/Articles/iOS10.html#//apple_ref/doc/uid/TP40017084-DontLinkElementID_2" rel="nofollow noreferrer">release notes</a> for iOS 10 features a section titled <strong>Wide Color</strong>.</p>

<p>The line that has me confused is this one:
<em>If your app relies on UIKit to clamp component values (whether you’re creating a color or asking a color for its component values), you need to change your app’s behavior when you link against iOS 10.</em></p>

<p>What does it mean to clamp component values??  What does that look like in objective-c or swift and how would I update it to comply with the changes coming in iOS 10?</p>
