[Swift] Split String in Swift by their capital letters

Give a string and return an array with it capital letters.
For example:

Input: "ShowMeTheMoney"
Output: ["Show","Me","The","Money"]

---------------------------------------
解法1:
去巡覽每個字母，如果那個字母是大寫(capital letter)，就在後面加一個空格(也可以用其他符號代替，但是用空格最好，晚一點說明)。之後整合成字串後再用Split分開成Array

	func splitCapitalString(_ textString:String) -> [String] {
	var newStringArray = [String]()
	for char in textString {
	if String(char) == String(char).uppercased() {
	newStringArray.append(" ")
	}
	newStringArray.append(String(char))
	}
	//joined 把加工後的array 變成字串 "HeMoYo" -> " He Mo Yo"
	//trimmingCharacters 移除左右空白
	//compoents 把空白拆開為Array, 也可以用 Split(separator:), 但是會回傳 SubSequence type
	return newStringArray.joined().trimmingCharacters(in: .whitespacesAndNewLines).compoents(separatedBy: " ")
	}
