即使对象存在，我也得到EXC_BAD_ACCESS(code = 1，address = 0x30)错误的访问权限-swift 4 [英] I am getting EXC_BAD_ACCESS (code=1, address=0x30) Bad Access even when object exists - swift 4

问题描述

类似于此SO帖子和此SO帖子

我初始化变量----> idHERE:

I initialize a variable ----> idHERE:

static func createPractitionerRole(fromRoleDict roleDict:[String: AnyObject])->PractitionerRole?{

    guard let (nameL, idL) = getRoleNameId(fromRoleDict:roleDict) else {
            return nil
    }

    let roleTypeL = ProTouchRoleType.determineRoleTypeFromProTouchId(idL)

    var idHERE =  Identifier(withValue: idL, systemParam:Constants.CodeSystem.ProTouch.coding_system_proTouchURL)

    print("idHERE \(String(describing:  idHERE))")

    print("idHERE.value \(String(describing:  idHERE.value))")

    return PractitionerRoleUtils.createPractitionerRole(withId:idHERE, name: nameL, roleType: roleTypeL)
}

在第一次打印时，它会打印出对象:

On the first print it prints out the object:

idHERE Identifier Object- system:Optional(http://www.anyApp.com/any) value:Optional("319/43") use:usual period:nil

但是当我尝试使用第二张照片时 idHERE.value-我无法访问EXC_BAD_ACCESS(代码= 1，地址= 0x30)

But on the second print when I try to use idHERE.value - I get a bad access EXC_BAD_ACCESS (code=1, address=0x30)

这怎么可能?

调试器也会很好地显示所有值.

The debugger shows all the values fine as well.

我尝试在没有帮助的情况下以发布模式运行代码.

I have tried running the code in release mode with no help.

请帮助！！

此外，我将其从let更改为var，以查看是否有所不同.

Also, I changed this from a let to a var to see if that made a difference.

经过一些复杂的代码之后，但是我不确定为什么会有所作为.为什么，如果您初始化了某些内容，之后又不能立即访问这些值呢?

This after some complicated code, but I'm not sure why that would make a difference. Why, if you initialize something, can't you access the values immediately after.

此外，不调用deinit.我有一个用于deinit的打印语句，它没有被调用.

Also, deinit is NOT called. I have a print statement for deinit and it is not called.

谢谢！

推荐答案

到目前为止，我唯一的解决方法是将发布和调试的优化级别更改为-02.现在它工作"了.迅捷的人需要看看这个！！

My only work around as of now is changing the optimization level to -02 for both release and debug. Now it "works". Someone from swift needs to look at this!!

访问权限也不佳，优化级别已更改
