在使用 xode 27 真机调试项目时报了 ibrary 'd64' not found 这个错误，企业微信截图_abf507f6-9ecc-4d60-ab9e-ef3d67c38433.png 这边有用到-ld64 遇到这个问题需要怎么去解决呢？ xcode 26 没有报这个错

Sadly, I can’t read Chinese, so I’m answering based on a machine translation.

There are a couple of issues here:

When you pass options to the linker using the OTHER_LDFLAGS build setting, you have to escape them with -Xlinker. Without that the options are are interpreted by the compiler driver, and it doesn’t understand -ld64 (it think you’re trying to a link, using -l, to a library called d64).
Additionally, the -ld64 linker option isn’t supported by the linker within Xcode 27. It always assumes ld_prime. I explain the history of this in An Apple Library Primer.

So, my advice is that you simple remove -ld64 from that build setting.
