var score = 0
var randomAmountOfTime = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime2 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime3 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime4 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime5 = Double(arc4random_uniform(5) + 2)

您正在无条件地递归调用 self.loadingProcess()。这个无限循环肯定会导致崩溃。
