OK, 已经复现了, 但是目前我不知道该如何解决, 是Xcode Optimization Level 导致的类型转换失败.

唯一能想到的是可以通过将Optimization Level 设置为none 来避免crash.

目前先使用强转规避了崩溃问题😂

get {
            if let temp = objc_getAssociatedObject(self, &UILabelActionsKey) {
                return temp as! [NSRange: Action]
            } else {
                return [:]
            }
        }

???? as! 可以规避吗? 类型应该是 [NSRange: [Action]] 不是 [NSRange: Action]

[EnjoyWT]

强转成需要的返回类型就可以了

as? 在 Xcode14 iOS12 Release Mode 下运行会导致类型转换出现null 导致crash. 已改为as! 绕过这个问题 后续等待苹果解决这个编译优化问题吧
