Annoyed by Xcode asking a name for each playground you create? Me too! Most often I use playgrounds I just want to try out something real quick.

readme.md

1. Create a playground from xcode which you are going to use as a template. Call it Template.playground or modify the script.
2. Put the script into the same directory.
3. chmod +x justplay. You can run the script from terminal. I decided to add it as a behavior to Xcode and to use default shortcut to run it.
4. In Xcode go to Xcode->Behaviors->Edit behaviors
5. Add a new behavior
6. Choose the justplay script to run for that behavior.
7. Assign a shortcut to it. I use a default shortcut for creating a playground: ⌥⇧⌘N

justplay

#!/bin/bash
set -e

TEMPLATE_NAME="Template.playground"

DESTINATION_PATH=`mktemp -d`/$TEMPLATE_NAME

cp -R "`dirname $0`/$TEMPLATE_NAME" $DESTINATION_PATH
open $DESTINATION_PATH
