没有使用public class UserAddress { public string Id { get; set; } public string Address1 { get; set; } public string Address2 { get; set; } public string ZipCode { get; set; } ' I don't know what to put here to connect this table with the AspNetUsers Table public int UserId {get;set} This doesn't work }作为完成，因此您可以删除它，而我从您的代码中看到的是，您尝试将CREATE TABLE mytable( FROMDATE DATE NOT NULL ,TODATE DATE ); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('15/02/2016','30/04/2016'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/05/2016',NULL); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('2/06/2016','16/10/2016'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('17/10/2016','31/12/2016'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/01/2017','14/02/2017'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('15/02/2017','31/12/2017'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/01/2018','14/02/2018'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('15/02/2018','20/02/2018'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('21/02/2018','31/03/2018'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/04/2018','31/12/2018'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/01/2019','31/03/2019'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/04/2019','31/12/2019'); INSERT INTO mytable(FROMDATE,TODATE) VALUES ('1/01/2020',NULL); select fromdate , todate as todate_raw , coalesce(todate,lag(fromdate,1) over(order by fromdate DESC)) as todate_new from mytable order by fromdate作为onSuccess接收。因此，我已经相应地更新了该代码。

Answer 2

Firebase Auth（）。createUser中的完成块的签名为（（（AuthDataResult ?, Error？）-> Void）？即它需要两个参数：结果和错误。您尚未包含任何内容，因此编译器假定您的完成块签名为（）->（）

通话的第一行应该是：

Auth().createUser(withEmail: email, password: password, completion: { result, error in

例如参见https://stackoverflow.com/a/36586581/1852207

无法将类型'（）->（）'的值转换为预期的参数类型'（（（AuthDataResult ?, Error？）-> Void）？'
