My advice would be: don't try this in a playground. Playgrounds aren't ready for this stuff yet. Your code compiles and runs fine in a real project. Here's an example:

Can a function take both IntoIterator and IntoIterator<&T>?

Asked 2021-Jun-15 at 12:28

I want a function that takes two arguments, both of which can be turned into an iterator of Foo. The snag is that I'd like to accept things which are both IntoIterator and also IntoIterator<&Foo>. Importantly Foo is Copy so I can cheaply create an owned copy from it's reference.

The solution I currently have is:

First of all, you don't need exactly IntoIterator bound here. It's just enough for Iterator.

Using multiple files in SwiftUI playground

Asked 2021-Jun-14 at 10:13

I am trying to use multiple files in SwiftUI playground. I added some code in a separate file in sources. I just want the sheet view to appear when the button is tapped. Even though I have made the struct public but I still get the error as " SecondView initializer is inaccessible due to internal protection level "

Here's the code:

ANSWER

Answered 2021-Jun-14 at 10:13

The default initialiser (the one generated by the compiler, since you didn't declare one explicitly) is actually internal.

This is documented here:

A default initializer has the same access level as the type it initializes, unless that type is defined as public. For a type that’s defined as public, the default initializer is considered internal. If you want a public type to be initializable with a no-argument initializer when used in another module, you must explicitly provide a public no-argument initializer yourself as part of the type’s definition.

So you should do:

'Token has been expired or revoked' - Google OAuth2 Refresh token gets expired in few days

Asked 2021-Jun-14 at 08:19

I am using google analytics api to fetch analytics data. I tried to authenticate it using following steps : -> created OAuth client id in https://console.developers.google.com/ credentials section. -> In consent screen I had set publishing status as testing -> In OAuth 2.0 Playground I got the refresh token using above generated client id and client secret -> Then I am using it to generate access token through it.

But After few days refresh token seem to expire again and again although it is mentioned that refresh token validity is life long.

Answered 2021-Feb-20 at 14:17

I needed to send mails from a gmail account that I have access to, using nodemailer. It works for a couple of days before my refresh token is mysteriously revoked, even though the account belongs to me. A google search brought me here and I had been watching for a while hoping someone would help with a solution.

As you mentioned, this seems to happen with only test/unverified apps and I'm guessing google revokes tokens for such applications in your account after a few days. After much trials and errors, here is what I did.

NOTE: This is solution is only applicable to accounts you own, otherwise you must verify your app to access other people's accounts

Generate a new refresh token (existing one is most likely revoked) as described in this SO post
Go to the security tab of your google account dashboard
Under the Recent security activity section, you should see a security alert for your app.
Click on the context menu next to the notification and click DISMISS
At this point you'll be presented with a dialog of options where you indicate the level of trust you have for the app. I just went ahead and said I trusted the developer/app, obviously. And that's it! The refresh token should persist after this.

I could not find anything related anywhere else. So, please, accept this answer if it works for you. It might help someone else

QUESTION

Google Drive API Listing Files with Field Paramter Not Working

Asked 2021-Jun-14 at 02:05

I am currently listing some files with the Google Drive API. However, the default list only lists id, name, and mimeType. I know that the fields parameter can list more than just the default, but when I put parents as a field in the Google API Playground, I get the error of Invalid field selection parents. However, when I use * in the fields parameter, it returns all the fields. Am I doing anything wrong by putting parents in the fields parameter? If so, does anyone have any idea how to include the parents field as a field in the list results?

Here is my current endpoint, which causes the error:

...

ANSWER

Answered 2021-Jun-14 at 02:05

From https://www.googleapis.com/drive/v3/files?fields=parents&key=[YOUR_API_KEY], in your situation, when parents is directly put to fields as follows,

such error of Invalid field selection parents occurs. Because the method of "Files: list" returns the file list which is an array including each file metadata. Ref I think that this is the reason of your issue.

Solution:

So in this case, please set files(parents) instead of parents.

Note:

In the case of files(parents), only parents is returned. When you want to retrieve id, name, mimeType and parents, please use files(id,name,mimeType,parents) to fields.
