ios - Mac Catalyst 应用程序在其他 Mac 上崩溃，但从 Xcode 运行时可以正常工作

Question

我在将我的 Mac 催化剂应用程序分发给测试人员时遇到问题，虽然它在我的机器上正常运行，但在其他机器上启动后立即崩溃，没有任何人类可理解的崩溃报告。

此外，当我们使用 Xcode 在该 Mac 上运行它时，它工作正常，但在运送到我的 Mac 时崩溃了。这是我所做的——我使用的是 Xcode 11.3.1，应用程序是自动签名的，我在发货前对其进行了无误公证。

有谁知道它为什么会崩溃？

好的，经过长时间的研究，我发现了这个问题。我们在我们的应用程序中使用了自定义字体并导致了崩溃，这似乎是苹果错误，因为字体已正确链接并添加到 Info.plist 中。同样在安装了字体的机器上，应用程序不会崩溃。将字体更改为 Apple 提供的类似字体后，该应用程序可以完美运行。
