#import <> changes to #import "" after using pods dependency in iOS

Before using the Pod, I manually introduced AMapSearchKit.framework, which works normally together. The way I import is this: #import <AMapSearchKit/AMapSearchKit.h>. Later I need to create my own Pod, edit the .podspec file, and add the dependency: s.dependency'AMapSearchKit'. After pod install is complete, I failed to compile. All #import <AMapSearchKit/AMapSearchKit.h> places that the file cannot be found, but #import "AMapSearchKit.h" is working.

I checked the settings of Framwork Search Paths are normal, I am not sure if I am missing something? I need to understand the difference between #import<> and #import"", the reason for this. Could anyone help me? thank you very much
