So how can I translate or is there just a different code for Swift?

from openai import OpenAI

client = OpenAI(
    base_url="", 
    api_key="" 
)

# Instruction for the API request: 
instruction = "..."

text = "..."

chat_completion = client.chat.completions.create(
    model="tgi",
    messages=[
        {"role": "system", "content": instruction},
        {"role": "user", "content": text},
    ],
    stream=True,
    max_tokens=2000
)

# iterate and print stream
for message in chat_completion:
    print(message.choices[0].delta.content, end="")

I have tried PythonKit(fails to run the app even with some default things) and OpenAIKit(there is no base_url field as far as I know)
