Update Repostory for swift 5

With `Swift 5` Xcode suggest me to change things like:
`NSLayoutFormatOptions` to `NSLayoutConstraint.FormatOptions.`
`NSLayoutAttribute.centerX` to `NSLayoutConstraint.Attribute.centerX`
`NSLayoutRelation.equal` to `NSLayoutConstraint.Relation.equal`
`bytes: 4, alignedTo: 1` to `byteCount: 4, alignment: 1`
