it helps some times If I understand correctly, you're looking for a way to convert a hex string into a Base64 string in Java.
It can be easily done with the Apache Commons Codec library:
String output = new String(Base64.encodeBase64(Hex.decodeHex(input.toCharArray())));

With these it helps As Martin R mention in his comment I tried options from other topic and I was doing conversion byte array bad way. This is correct method in swift:
class func base64ToByteArray(base64String: String) -> [UInt8]? {
      if let nsdata = NSData(base64EncodedString: base64String, options: nil) {
          var bytes = [UInt8](count: nsdata.length, repeatedValue: 0)
          nsdata.getBytes(&bytes)
          return bytes
      }
      return nil // Invalid input
}
if let nsdata = NSData(base64EncodedString: base64String, options: NSDataBase64DecodingOptions.IgnoreUnknownCharacters) {
...

Convert u8 array to base64 string in Rust

I hope this helps . What you're looking for is the base64 crate, particularly its encode() function. Usage is pretty straightforward:
extern crate base64;

fn main() {
    let data: Vec<u8> = vec![1,2,3,4,5];
    println!("{}", base64::encode(&data))
}

Can a byte[] array ever not convert to a Base64 string?

I hope this helps you .
Is there any combination of a byte[] that will cause this to fail
byte[] byteArray = null;
var myString = Convert.ToBase64String(byteArray);
// NullArgumentException.
var byteArray = new byte[] {255, 255, 0};
var myString = Convert.ToBase64String(byteArray);
Console.WriteLine(myString); // +voA
var byteArray = new byte[] {0, 250, 250};
var myString = Convert.ToBase64String(byteArray);
Console.WriteLine(myString); // APr6
var byteArray = new byte[] {250, 250};
var myString = Convert.ToBase64String(byteArray);
Console.WriteLine(myString); // +vo=
var byteArray = new byte[] {};
var myString = Convert.ToBase64String(byteArray);
Console.WriteLine(myString.Length); // 0
var byteArray = new byte[int.MaxValue]; // OutOfMemoryException
var byteArray = new byte[int.MaxValue / 8];
var myString = Convert.ToBase64String(byteArray);
Console.WriteLine(myString.Length); // 357913940
