这是由于type 和 type(of:) 重名！
方式一：按照下面👇方式修改
-------------Metadata.swift 中：-------------
init?(anyType: Any.Type) {
self.init(pointer: unsafeBitCast(anyType, to: UnsafePointer.self))
if let kind = type(of: self).kind, kind != self.kind {
return nil
}
}

-------------Properties.swift 中-------------
func getProperties(forType type: Any.Type) -> [Property.Description]? {
if let nominalType = Metadata.Struct(anyType: type) {
return fetchProperties(nominalType: nominalType)
} else if let nominalType = Metadata.Class(anyType: type) {
return nominalType.properties()
} else if let nominalType = Metadata.ObjcClassWrapper(anyType: type),
let targetType = nominalType.targetType {
return getProperties(forType: targetType)
} else {
return nil
}
}
-------------Metadata.swift中-------------
guard let metaclass = Metadata.Class(anyType: superclass), metaclass.isSwiftClass else {
return nil
}

方式二：按照下面👇方式修改
-------------Metadata.swift 中：-------------
init?(type anyType: Any.Type) {
self.init(pointer: unsafeBitCast(anyType, to: UnsafePointer.self))
if let kind = type(of: self).kind, kind != self.kind {
return nil
}
}

-------------Properties.swift 中-------------
func getProperties(forType anyType: Any.Type) -> [Property.Description]? {
if let nominalType = Metadata.Struct(type: anyType) {
return fetchProperties(nominalType: nominalType)
} else if let nominalType = Metadata.Class(type: anyType) {
return nominalType.properties()
} else if let nominalType = Metadata.ObjcClassWrapper(type: anyType),
let targetType = nominalType.targetType {
return getProperties(forType: targetType)
} else {
return nil
}
}

太感谢了，就是和type(of:)重名了，按照上面的修改，运行很顺畅

@XDYB 这上面的代码会被加入到下一个的Pod版本的库吗？

please use english language

@arashgood just following the instruction as @XDYB commented above, it did work.

@VictorZhang2014 it's not clear instruction!

@arashgood It did well for me. Another helping instruction is to download the whole project and run it in the simulator or iphone which always runs well.

@XDYB Sorry to copy your answer here.

This error is appeared by a type and type(of:)

Solution 1:

1. Follow these instructions below and modification

-------------in the file of Metadata.swift ：-------------

init?(anyType: Any.Type) {
    self.init(pointer: unsafeBitCast(anyType, to: UnsafePointer.self))
    if let kind = type(of: self).kind, kind != self.kind {
        return nil
    }
}

-------------in the file of Properties.swift-------------

func getProperties(forType type: Any.Type) -> [Property.Description]? {
    if let nominalType = Metadata.Struct(anyType: type) {
        return fetchProperties(nominalType: nominalType)
    } else if let nominalType = Metadata.Class(anyType: type) {
        return nominalType.properties()
    } else if let nominalType = Metadata.ObjcClassWrapper(anyType: type),
        let targetType = nominalType.targetType {
    return getProperties(forType: targetType)
