[
When building and running my iOS app from xcode, the following message appears in the terminal (iPhone 4s running 9.3.6).
Could not find implementation lookup function
“class_getMethodImplementation” step in through ObjC method dispatch
will not work.
This message does not appear on my iPhone X on iOS 14.4.
What does this mean? I have been unable to find any documentation related to this message.
,
It is a warning from LLDB (the debugger) saying that it cannot find class_getMethodImplementation (a method in the Obj-C runtime), and that will prevent it from stepping through message dispatch.
Which may not help you much… Why LLDB cannot find that method is something you’ll have to figure out, as is whether it is a significant warning.
You can find the LLDB error on line 726 of this source file.
