在 Xcode 模拟器中更改时间和日期

Question

如何在 iPhone 模拟器中更改时间？我希望我手机上的其他应用程序看到与当前不同的时间。

老问题，现代答案：

With Xcode 11, Apple shipped new features for the simctl tool，它允许您通过覆盖状态栏值来更好地控制模拟器的外观。

找到正确的设备
命令xcrun simctl listlists the currently installed simulators and gives their status：

% xcrun simctl list
== Device Types ==
<list of device types>

== Runtimes ==
<list of runtimes>

== Devices ==
-- iOS 13.5 --
    iPhone 11 (A2A694CF-8DA3-4371-AD2D-A2592A5C770C) (Shutdown) 
    iPhone 11 Pro (F36583E8-6833-4526-8622-CE24022BE876) (Booted) 
    iPhone 11 Pro Max (82029941-193B-423E-BE89-DD3E1C0B12E6) (Shutdown) 

这个命令的输出很长，所以 NSHipster 很好地提供了一个在their simctl article 中打印当前启动设备的UDID 的命令：

$ xcrun simctl list devices | \
    grep "(Booted)"         | \
    grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})"
9FED67A2-3D0A-4C9C-88AC-28A9CCA44C60 

获取适当的设备 UDID 并将其传递给以下命令以更改模拟器的当前时间：

% xcrun simctl status_bar F36583E8-6833-4526-8622-CE24022BE876 override --time "9:41"
%

运行xcrun simctl help status_bar 将显示全方位的选项：

$ xcrun simctl help status_bar
Set or clear status bar overrides
Usage: simctl status_bar <device> [list | clear | override <override arguments>]

Supported Operations:
    list
    List existing overrides.

    clear
    Clear all existing status bar overrides.

    override <override arguments>
    Set status bar override values, according to these flags.
    You may specify any combination of these flags (at least one is required):

    --time <string>
         Set the date or time to a fixed value.
         If the string is a valid ISO date string it will also set the date on relevant devices.
    --dataNetwork <dataNetworkType>
         If specified must be one of 'wifi', '3g', '4g', 'lte', 'lte-a', or 'lte+'.
    --wifiMode <mode>
         If specified must be one of 'searching', 'failed', or 'active'.
    --wifiBars <int>
         If specified must be 0-3.
    --cellularMode <mode>
         If specified must be one of 'notSupported', 'searching', 'failed', or 'active'.
    --cellularBars <int>
         If specified must be 0-4.
    --operatorName <string>
         Set the cellular operator/carrier name. Use '' for the empty string.
    --batteryState <state>
         If specified must be one of 'charging', 'charged', or 'discharging'.
    --batteryLevel <int>
         If specified must be 0-100.

在主机 Mac 上更改系统时间。模拟器运行一个单独的用户空间，但共享内核，因此它没有与主机不同时间的概念。
