 * Takes in a parsed simulator list and a desired name, and returns an object with the matching simulator. The desired
 * name can optionally include the iOS version in between parenthesis after the device name. Ex: "iPhone 6 (9.2)" in
 * which case it'll attempt to find a simulator with the exact version specified.
 *
 * If the simulatorString argument is null, we'll go into default mode and return the currently booted simulator, or if
 * none is booted, it will be the first in the list.
 *
 * @param Object simulators a parsed list from `xcrun simctl list --json devices` command
 * @param String|null simulatorString the string with the name of desired simulator. If null, it will use the currently
 *        booted simulator, or if none are booted, the first in the list.
 * @returns {Object} {udid, name, version}
