ios - 如何初始化 CLLocationCoordinate2D 结构

您发现了一个非常不寻常且有趣的错误。我可以通过在空白 iOS 游乐场中运行以下代码来重现您的问题：

import UIKit
import CoreLocation

var temporaryCoordinate = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)

问题出在运行时环境 Playground 本身正在崩溃。在 Mac 中，在控制台应用程序中，使用 Crash Reports 左侧选项卡，我们可以看到 Xcode Playground 正在崩溃。

我认为问题在于有两个核心位置二进制文件在起作用：

0x18321e000 -        0x1832a8fff  com.apple.corelocation (2420.12.16 - 2420.12.16) <F94D1F57-86D5-3A82-8F2B-80A9AEAC0308> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreLocation.framework/CoreLocation

和

0x1b1f96000 -        0x1b1f98fff +libswiftCoreLocation.dylib (5) <EE615605-C11D-3F60-B611-8B1C1D45FEEA> /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftCoreLocation.dylib

操场正在从一个世界到另一个世界进行交流；与 iOS 模拟器交谈。但是两者之间存在不兼容，因为由于类型混淆，消息没有正确传递。这导致

*** 由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“+ [NSValue valueWithMKCoordinate:]：无法识别的选择器发送到类 0x1c9d3f588”以未捕获的 NSException 类型异常终止

我认为您应该向 Apple 提交错误。为避免此问题，请直接基于 iOS 模拟器编写代码，而不是使用 Playground。在这种情况下，您的代码将正确执行（因为它将直接针对模拟器运行，而无需来自 Playground 的干预桥）。
