A Swift Library for dumping objective-c class/protocol/method/property/ivar informations.
Information on Objective-C class/protocol/method/property/ivar can be obtained as follows.
import ObjCDump
// Class
let info = classInfo(of: NSObject.self)
let methods = info.methods
/* or */
let methods = methods(of: NSObject.self, isInstance: true)
// Protocol
let `prtocol` = NSProtocolFromString("NSCoding")!
let info = protocolInfo(of: `protocol`)
let methods = info.optionalMethods
/* or */
let methods = methods(of: `protocol`, isRequired: false, isInstance: true)
// Method
let method = class_getInstanceMethod(NSObject.self, NSSelectorFromString("init"))!
let info = ObjCMethodInfo(method)
// Property
let property = class_getProperty(NSObject.self, "classDescription")!
let info = ObjCPropertyInfo(method)
// Ivar
let ivar: Ivar = /**/
let info = ObjCIvarInfo(ivar)It is possible to output Objective-C headers as follows.
import ObjCDump
let info = classInfo(of: NSObject.self)
print(info.headerString)
/*

*/The type information obtained at ObjC line time is encoded. This is the same conversion that can be obtained with the @encode directive in Objective-C.
As there are no published functions for decoding this encoded type information, a new decoder has been implemented. It can be used as follows
import ObjCTypeDecodeKit
let type = ObjCTypeDecoder.decode("(?=iI{?=i{CGRect={CGPoint=dd}{CGSize=dd}}})")
print(type.decoded())
/*
union {
int x0;
unsigned int x1;
struct {
int x0;
struct CGRect {
struct CGPoint {
double x0;
double x1;
} x0;
struct CGSize {
double x0;
double x1;
} x1;
} x1;
} x2;
}
