Swift separate String into array of data split at certain characters

Question

I need to dissect a String into multiple parts to put into an array. The string needs to be split at a specific set of characters.

For example: If I need to split this string at each "{=" occurrence, the string:

"{=hello{=secondindex{=stuffhere"

would turn into an array like this:

["hello", "secondindex", "stuffhere"]

Help is very much appreciated, I thank you in advance.
