@raitomakesgames says

hey @jcesarmobile, yes I know. The issue we are having is when we are recording a video.

Tue, 01 Dec 2020 19:22:06 GMT

@mpriddy says

Howdy, sports fans.

Tue, 01 Dec 2020 19:23:14 GMT

@mpriddy says

I’m running into a problem with migrating to WKWebView - and can’t figure out how to inspect my app in the iOS simulator.

Tue, 01 Dec 2020 19:24:19 GMT

@mpriddy says

The iOS simulator doesn’t have an option to enable it in the Safari settings - and what I’ve read suggests that remote inspection is “always on” in the iOS simulator.

Tue, 01 Dec 2020 19:24:44 GMT

@mpriddy says

Despite this, the simulator doesn’t show up in the Safari Develop menu.

Tue, 01 Dec 2020 19:26:11 GMT

@norman137 says

Depending on what version of iOS you're running you may need to use the Safari Tech Preview on the mac

Tue, 01 Dec 2020 19:26:35 GMT

@mpriddy says

Hmm. I have that laying around.

Tue, 01 Dec 2020 19:27:54 GMT

@mpriddy says

Nice! That worked.

Tue, 01 Dec 2020 19:28:32 GMT

@mpriddy says

I hadn’t seen that tidbit anywhere, Norman. Thank you!

Tue, 01 Dec 2020 19:28:39 GMT

@mpriddy says

Now let’s get this thing to break again.

Tue, 01 Dec 2020 19:28:40 GMT

@mpriddy says

😄

Tue, 01 Dec 2020 19:29:26 GMT

@norman137 says

Apple likes to release ios versions and their mac safari counterpart lags behind so the current prod version of safari doesn't know how to communicate with the newer ios safari.

Tue, 01 Dec 2020 19:30:15 GMT

@mpriddy says

I see. Does … the … number in the simulator represent the version of iOS its running?

Tue, 01 Dec 2020 19:30:26 GMT

@mpriddy says

Tue, 01 Dec 2020 19:31:36 GMT

@mpriddy says

That appears to be the case.

Tue, 01 Dec 2020 19:31:40 GMT

@norman137 says

I believe so

Tue, 01 Dec 2020 19:31:56 GMT

@mpriddy says

I took a look in the Settings > General > About

Tue, 01 Dec 2020 19:32:00 GMT

@mpriddy says

And those values match.

Tue, 01 Dec 2020 19:32:20 GMT

@norman137 says

iOS 12 is a bit old now, maybe in your case you just aren't running teh latest version of Mac OS

Tue, 01 Dec 2020 19:32:21 GMT

@norman137 says

?

Tue, 01 Dec 2020 19:32:36 GMT

@mpriddy says

I’m on Catalina - so, not quite to Big Sur yet.

Tue, 01 Dec 2020 19:33:16 GMT

@norman137 says

I'm not that familiar with the apple ecosystem but I think safari is locked to the os or is it independently updatable?

Tue, 01 Dec 2020 19:33:28 GMT

@mpriddy says

It sometimes gets updates.

Tue, 01 Dec 2020 19:33:33 GMT

@mpriddy says

Independent updates, I mean.

Tue, 01 Dec 2020 19:33:51 GMT

@mpriddy says

But those are more like bug fixes or security patches, I think.

Tue, 01 Dec 2020 19:34:00 GMT

@dpogue says

Safari gets updates, iOS simulator versions are tied to the Xcode version

Tue, 01 Dec 2020 19:34:01 GMT

@norman137 says

weird, woudln't expect that you needed to use the tech preview for iOS 12 devices/simulators

Tue, 01 Dec 2020 19:34:11 GMT

@dpogue says

You can run Xcode 12 (with iOS 14) on Catalina

Tue, 01 Dec 2020 19:34:21 GMT

@mpriddy says

Agree, Norman. Just happy as hell that it worked.

Tue, 01 Dec 2020 19:34:29 GMT

@dpogue says

but to debug iOS 14, you'll need the latest Safari too

Tue, 01 Dec 2020 19:34:49 GMT

@mpriddy says

Yeah, the iPhone 11 and 12 simulators run ios 14.2

Tue, 01 Dec 2020 19:35:04 GMT

@mpriddy says

(on my Mac, to clarify)

Tue, 01 Dec 2020 19:41:46 GMT

@mpriddy says

I was thinking that WKWebView was failing to load my app because of CORS violations. But I’m not seeing anything in the console.

Tue, 01 Dec 2020 19:46:04 GMT

@norman137 says

if the error is happening on startup, you'd need to refresh the webview to see it in the console. You can refresh the webview by pressing cmd+r while the inspector is focused.

Tue, 01 Dec 2020 20:14:04 GMT

@mpriddy says

I’ll give that a try, too.

Tue, 01 Dec 2020 20:18:15 GMT

@norman137 says

Basically inspector won't report on errors that occurred before the inspector was attached.

Tue, 01 Dec 2020 20:27:04 GMT

@mpriddy says

Turns out that it IS a CORS error. So I’ve updated the project to cordova-ios 6.1.1 - and still get the CORS errors.

Tue, 01 Dec 2020 20:28:15 GMT

@norman137 says

Are you accessing a remote resource or a local resource?

Tue, 01 Dec 2020 20:28:22 GMT

@mpriddy says

Local

Tue, 01 Dec 2020 20:28:33 GMT

@norman137 says

Are you using schemes?

Tue, 01 Dec 2020 20:28:41 GMT

@mpriddy says

Not sure what that means, so probably not.

Tue, 01 Dec 2020 20:29:40 GMT

@norman137 says

By default cordova-ios still uses the file:// protocol, mainly because by moving away from that protocol to a scheme, your origin changes, which means you lose access to your web storage containers, such as local storage, indexeddb, cookies, etc.

Tue, 01 Dec 2020 20:30:03 GMT

@norman137 says

So you have 2 options...

Tue, 01 Dec 2020 20:30:14 GMT

@mpriddy says

Mmm kay, the errors all do holler about file://

Tue, 01 Dec 2020 20:30:35 GMT

@norman137 says

If maintaining those local storage containers is important and you don't wanna deal with migrating data

Tue, 01 Dec 2020 20:31:47 GMT

@norman137 says

Then you have to use a plugin... https://github.com/oracle/cordova-plugin-wkwebview-file-xhr

If you can afford to deal with data migration or the data stored in web storage containers is easily reconstructable... the better approach would be to use schemes... link incoming

Tue, 01 Dec 2020 20:32:25 GMT

@norman137 says

https://cordova.apache.org/howto/2020/07/18/uiwebview-warning.html

Tue, 01 Dec 2020 20:32:50 GMT

@norman137 says

<preference
&lt;preference name="hostname" value="localhost" /&gt;```
should be added inside `config.xml`

Tue, 01 Dec 2020 20:33:05 GMT

@mpriddy says

So, use schemes if I can - recreating local storage should be OK.

Tue, 01 Dec 2020 20:34:25 GMT

@mpriddy says

I’m having difficulty identifying where the dividing line is between these two solutions.

Tue, 01 Dec 2020 20:36:02 GMT

@norman137 says

if you don't care about maintaining data in local storage/cookies/indexedb, etc... ie the data can be easily replaced, then use schemes. Schemes solves many issues surrounding cors and other web restrictions that occur when using the file:// protocol.

Tue, 01 Dec 2020 20:36:35 GMT

@mpriddy says

I am pretty sure that rebuilding localstorage is going to be OK.

Tue, 01 Dec 2020 20:37:10 GMT

@mpriddy says

So I’m leaning toward the schemes solution. Does that involve only adding those two preferences to the config.xml - or is there more to it?

Tue, 01 Dec 2020 20:37:20 GMT

@norman137 says

Nope that should be it.

Tue, 01 Dec 2020 20:37:41 GMT

@norman137 says

Your app will appear to be hosted from <app://localhost> instead of file://

Tue, 01 Dec 2020 20:38:10 GMT

@mpriddy says

Do those options need to be wrapped in &lt;platform name="ios"&gt; or can they just be “bare” in the config?

Tue, 01 Dec 2020 20:38:15 GMT

@norman137 says

You can change the scheme to your preference, but you cannot use well known schemes such as http or https... and once you pick one you'd want to stick with it

Tue, 01 Dec 2020 20:38:32 GMT

@norman137 says

I believe bare

Tue, 01 Dec 2020 20:38:43 GMT

@mpriddy says

Cools. I’ma see what breaks next. 😄

Tue, 01 Dec 2020 20:39:59 GMT

@norman137 says

I haven't actually used this yet myself 😅 my apps still on [email protected] with wkwebview plugin -- so I'm not using schemes

Tue, 01 Dec 2020 20:40:59 GMT

@mpriddy says

Woot! It builds and runs in the simulator.

Tue, 01 Dec 2020 23:00:38 GMT

@mpriddy says

Predictably, I’m getting CORS errors from switching to WKWebView

Tue, 01 Dec 2020 23:01:25 GMT

@mpriddy says

For downloaded local files, I solve this problem by replacing file:// with <app://localhost>

Tue, 01 Dec 2020 23:02:11 GMT

@mpriddy says

But I’m getting CORS errors for remote resources, too: > Origin <app://localhost> is not allowed by Access-Control-Allow-Origin.

Tue, 01 Dec 2020 23:02:48 GMT

@mpriddy says

So, would that require headers to be added to the remote web server?

Tue, 01 Dec 2020 23:19:28 GMT

@norman137 says

yah

Tue, 01 Dec 2020 23:19:35 GMT

@norman137 says

so schemes solves CORS issues when fetching local sources

Tue, 01 Dec 2020 23:19:52 GMT

@norman137 says

But if you're communicating with external servers, the server needs to respond with the appropriate CORS headers

Tue, 01 Dec 2020 23:20:59 GMT

@norman137 says

If you're new to CORS, I would recommend reading through https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

I also have a blog post that is more specific to cordova on CORS at https://breautek.com/2020/07/14/enabling-cors/

Tue, 01 Dec 2020 23:21:05 GMT

@mpriddy says

So, my DevOps team would need to modify our web server to send Access-Control-Allow-Origin: <app://localhost> or something?

Tue, 01 Dec 2020 23:22:36 GMT

@norman137 says

Yes

Tue, 01 Dec 2020 23:22:57 GMT

@mpriddy says

Your feedback is invaluable. Thank you.

Tue, 01 Dec 2020 23:23:47 GMT

@norman137 says

It doesn't have to be static either, my server does this dynamically by looking at the request Origin header and if it's acceptable, then I set the Access-Control-Allow-Originon the response to the value of the request Origin header.

Tue, 01 Dec 2020 23:24:44 GMT

@norman137 says

the origin will be for the cordova app will be &lt;scheme&gt;://&lt;hostname&gt; as set via the preferences earlier in config.xml

Tue, 01 Dec 2020 23:25:18 GMT

@mpriddy says

Just as I suspected. I’m sending off the request to our DevOps team.

@joel says

Hello! I have a plugin using the podspec element and use-frameworks attribute, however the generated Podfile does not have the use_frameworks! directive after prepare and build has been run. I think it should be there, but not 100% sure on the mechanics. What file can I look at to debug the creation of the Podfile? cordova-ios 6.1.1, cordova 9.0.0.

Tue, 01 Dec 2020 19:57:00 GMT

@joel says

Or just as a starter, is anyone using the use-frameworks attribute?

Tue, 01 Dec 2020 19:58:15 GMT

@dpogue says

yeah, I have a plugin that does and it seems to work...

<podspec>
      &lt;config&gt;&lt;/config&gt;
      &lt;pods use-frameworks="true"&gt;
        &lt;pod name="Example" /&gt;
      &lt;/pods&gt;
    &lt;/podspec&gt;```

Tue, 01 Dec 2020 20:01:37 GMT

@joel says

It's on the pods sub element 🤦‍♂️ .

trying to downgrade npm

Tue, 01 Dec 2020 13:24:37 GMT

@kkubicki2 says

any recommendation what version to install ?

Tue, 01 Dec 2020 13:24:40 GMT

@norman137 says

In general, bleeding edge versions, AKA odd-versions of node isn't tested or supported as these are short-lived versions. Most of the time they'll work, but mileage may vary.

More specifically NPM 7 have some changes that breaks the cordova tooling, which produces that result you just pasted.

npm install npm@6 -g will downgrade NPM back down to 6, but your milage may still vary on Node 15.

Tue, 01 Dec 2020 13:25:36 GMT

@norman137 says

It's a bit odd though...

> TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined Generally I only see this with users running < Node 10.10 -- because Cordova uses a feature that was only introduced starting Node 10.10.

Tue, 01 Dec 2020 13:26:20 GMT

@norman137 says

But perhaps in this case, it's being caused by a side effect of the npm problem

Tue, 01 Dec 2020 13:26:37 GMT

@kkubicki2 says

I'm also on Big Sur so maybe that's the issue too 😞

Tue, 01 Dec 2020 13:26:57 GMT

@prasunjajodia says

sidenote, if you want to work with bleeding edge but have to downgrade at times for projects, I recommend you use something like NVM (node version manager) Helps you switch between node and npm versions very quickly

Tue, 01 Dec 2020 13:27:57 GMT

@norman137 says

https://github.com/apache/cordova-lib/issues/859 this is our tracking ticket for the NPM 7 issue, if you want to subscribe to see updates onit.

Tue, 01 Dec 2020 13:29:37 GMT

dowograding npm worked like a CHARM. If theres' any way I can thank you let me know 🙂 have a nice day, I sure will 🙂

Tue, 01 Dec 2020 13:30:21 GMT

@norman137 says

Well it's good to know that ERR_INVALID_ARG_TYPE can be also caused by using NPM 7.

@kkubicki2 says

it all started when I wanted to include aar instead of jar in my plugin

Tue, 01 Dec 2020 13:31:13 GMT

@kkubicki2 says

I probably updated npm somewhere along the way...

Tue, 01 Dec 2020 13:31:16 GMT

@kkubicki2 says

weird

Tue, 01 Dec 2020 13:31:21 GMT

@kkubicki2 says

the old project still runs

Tue, 01 Dec 2020 13:32:04 GMT

@norman137 says

I think NPM 7 is included by default with Node 15.

Tue, 01 Dec 2020 13:32:20 GMT

@norman137 says

So by installing Node 15, you get NPM 7 installed as well.

Tue, 01 Dec 2020 13:32:35 GMT

@kkubicki2 says

I use homebrew on mac

Tue, 01 Dec 2020 13:33:10 GMT

@kkubicki2 says

installed all the latest and then downgraded, as per your recomendation. Well... phew... that was a long one, perhaps my aar will now work 🙂

@chadwick.blackford says

Hallo guys! why “market://” url schema doesn’t work on cordova-android@9? We have default config &lt;allow-intent href="market:*"/&gt; But IAB show error: net:ERR_UNKNOWN_URL_SCHEME

should I add &lt;allow-navigation href="market://*" /&gt; too?

Tue, 01 Dec 2020 18:57:54 GMT

@jcesarmobile says

Allow-intent is for cordova webview only, not IAB

Tue, 01 Dec 2020 18:59:03 GMT

@jcesarmobile says

Well, depends on the target you used on IAB, but IAB is really used when you launch with _blank

Tue, 01 Dec 2020 19:13:56 GMT

@chadwick.blackford says

I fixed this with _system

Tue, 01 Dec 2020 19:14:34 GMT

@chadwick.blackford says

adding this &lt;allow-navigation href="market://*" /&gt; doesn’t help with IAB
