Warnings from Swift 5.2 compiler

[timbms]

Description:

• Have a no warning when compiling

• Actual behaviour: Swift 5.2 included in Xcode Version 11.4 beta (11N111s) reports 2 warnings:

  1. In Queryable.swift var prefixChars = [CChar]()

     Initialization of variable 'prefixChars' was never used; consider replacing with assignment to '_' or removing it

2. In Document.swift

   public convenience init(cChars: [CChar]) throws {
   try self.init(buffer: UnsafeBufferPointer(start: UnsafePointer(cChars), count: cChars.count))
   }

   Initialization of 'UnsafePointer' (aka 'UnsafePointer') results in a dangling pointer

and also gives instructions on how to address:

1. Implicit argument conversion from '[CChar]' (aka 'Array') to 'UnsafePointer' (aka 'UnsafePointer') produces a pointer valid only for the duration of the call to 'init(_:)'
2. Use the 'withUnsafeBufferPointer' method on Array in order to explicitly convert argument to buffer pointer valid for a defined scope
