如果我有以下String，如何在 Swift 4 中将其转换为 Dictionary？

{"cover_image":"CI","profile_image":"PI","github":"","location":"Somewhere between the north pole and the south pole","name":"R","website":"mysitesucksyoudon'twannavisititrightnow.imforreal","about":"Yeah, I'm a human."}

【解决方案1】：

你可以使用JSONSerialisation方法class func jsonObject(with data: Data, options opt: JSONSerialization.ReadingOptions = []) throws -> Any：

let str = """
{"cover_image":"CI","profile_image":"PI","github":"","location":"Somewhere between the north pole and the south pole","name":"R","website":"mysitesucksyoudon'twannavisititrightnow.imforreal","about":"Yeah, I'm a human."}
"""
let dict = (try? JSONSerialization.jsonObject(with: Data(str.utf8))) as? [String:String] ?? [:]

print(dict)  // ["name": "R", "location": "Somewhere between the north pole and the south pole", "website": "mysitesucksyoudon\'twannavisititrightnow.imforreal", "github": "", "cover_image": "CI", "about": "Yeah, I\'m a human.", "profile_image": "PI"]

我建议改用 Codable
