swift getCheckedRoot(fileId: ) will assert on buffer < (8?) bytes rather than throw. [swift, swiftc 6.0, OSX, 24.3.25]

[peeeeter]

let dutData : [UInt8] = [1,2,3]
var buff  = ByteBuffer(bytes: dutData)
let foo: Foo = try getCheckedRoot(byteBuffer: &buff, fileId: "ABCD")
  FlatBuffers/ByteBuffer.swift:470: Assertion failed: Reading out of bounds is illegal

With try getCheckedRoot(byteBuffer: &buff), throws an out of bounds error (which seems correct), but with "fileid", you get an unrecoverable assert.

Hey,

Thanks for opening this issue! Yeah, just checked the code and I do see the issue. we directly try to read the ID for the file before verifying if the buffer has enough bytes within it to actually read that string! I've been super busy lately, so I won't be able to fix this anytime soon but I will try to push for a couple of fixes within the swift code soonish hopefully

  mutating func verify(id: String) throws {
    let size = MemoryLayout<Int32>.size
    let str = _buffer.readString(at: size, count: size)
    if id == str {
      return
    }
    throw FlatbuffersErrors.bufferIdDidntMatchPassedId
  }
