The camera button isn't showing up?

I followed everything as far as I can tell, but there isn't a button showing up in the bottom. I'm using Xcode 8 and swift 3 though, so I'm worried i've done something wrong..

Try downloading the project files and making sure that you have copied the snippets right!

I am using Xcode 8 and Swift 3 and there is no problem.

However, the video has omitted an additional step to be done in Info.plist that may result in fatal error when clicking the camera button.

From Apple Docs: To protect user privacy, an iOS app linked on or after iOS 10.0, and which accesses the user’s photo library, must statically declare the intent to do so. Include the NSPhotoLibraryUsageDescription key in your app’s Info.plist file and provide a purpose string for this key. If your app attempts to access the user’s photo library without a corresponding purpose string, your app exits.

Have fun coding!

p.s. same concept for accessing camera

Just to clarify how to resolve the NSPhotoLibraryUsageDescription error for iOS 10.

Go to info.plist Click + sign on the last item in list Under 'Information Property List' choose Privacy - Photo Library Usage Description in the 'Value' column put 'FaceSnap requires access to the photo library'. save

run simulator and push button. Permission pop up should appear with the text in the Value column.
