let file: string = "......./test.data" let p1 = person() p1.name = "person1" wirte(p1,to: file)

let p2 = person() p2.name = "person2" wirte(p2,to: file)

应该是[p1,p2]，但是只有p2

这是合理的

CoderMJLee commented 5 years ago

你的需求可以这样实现


let p1 = Person()
var ps = [p1]
write(ps, to: file)

let p2 = Person() ps.append(p2) write(ps, to: file)

- 或者
```swift
let p1 = Person()
write([p1], to: file)

let p2 = Person()
var ps = read([Person].self, from: file)
ps.append(p2)
write(ps, to: file)

我建议可以提供一个接口 write(addOrUpdate: p2,to: file) ,内部代码是

var ps = read([Person].self, from: file) ps.append(p2) write(ps, to: file)

上层代码不管这些细节

谢谢建议，下个版本考虑下
