Add experimental support for IOS native target

[jan-tennert]

What kind of change does this PR introduce?

Feature

What is the current behavior?

No support for IOS

What is the new behavior?

Support for iosArm64, iosSimulatorArm64, and iosX64 including deeplinking (syntax same as android)

Additional context

I cannot really test this PR as I don't have Mac myself to run a IOS Emulator on. I'm also not really familiar with IOS programming. Help would be appreciated

If you want to help, there is a version supporting IOS: 0.8.5-ios

Currently needed: Feedback for deeplinking

To enable deeplinking, setup an URL Scheme
and set the host & scheme in the gotrue plugin:

install(GoTrue) {
    scheme = "supacompose"
    host = "login"
}

And on startup, call client.handleDeeplinks(url)

[jan-tennert]

Published a version (0.8.0-beta-2-ios) with support for IOS, testing would be appreciated! If you also can test deep linking, the syntax is the same as Android but with URL Schemes

For what it's worth, I've been testing this a bit in my own app and have not had any issues on the iOS side - things look great. Haven't had the chance to test deep linking though

Great! Once the deep linking is settled, I'll merge this PR. I'm unsure about one thing: On Android supabase-kt pause and resumes auto refresh for the GoTrue session. Should this also be done on IOS/how would one implement this on IOS (using Kotlin of course)?

@jan-tennert could you please add the support for Arm64 simulator targets?

I'm not able to call the api that required bearer token (e.g. retrieveUserForCurrentSession(), refreshCurrentSession()..), somehow it will send two tokens in Authorization header. Is it a bug?

Yes that was indeed a bug, ktor was adding an access token twice. Should be fixed in version 0.8.5-ios

[jan-tennert]

@seankcw @jollygreenegiant Did anyone get the chance to test out deeplinking?

[seankcw]

@jan-tennert I tested 0.8.5 I can successfully log in with my account, but I haven't tested the deep linking on client-side project, because I'm doing deeplink/token verification in KMM directly (with MVI pattern).
I think the current version is still good to go.

Alright, thanks! Then I'll merge this PR for now

I was testing it, but when deeplink is handled, in URL object are data, but method handleDeeplink don't save data. When I am calling supabaseClient.gotrue.currentAccessTokenOrNull() I am getting null.
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any]) -> Bool { SupaBaseHelper().handleDeeplinks(url: url) return true }
in handleDeeplinks I am calling supabaseClient.handleDeeplinks(url)
supabaseClient is shared from DI by Koin.

on Android is working well.
can somebody help me? I am using version 0.9.3.

Couldnt test out deeplinking as I stated. Can you print out url.fragment and show me how it looks like? (dont show the access token if there is one)

[ldobransky]

here is output from fragment.url print:
Optional("access_token={access_token}&expires_in=3600&provider_token={provider_token}&refresh_token={refresh_token}&token_type=bearer")
values in {} was changed, there was tokens.

Okay that looks alright, I published a dev version 0.9.4-dev-1 with further logging and changes. Can you enable logging and show what is says?

[ldobransky]

I added 0.9.4-dev-1 logs bellow:
💚 DEBUG OAuthProvider.openOAuthlambda - Successfully opened provider url in safari 💚 DEBUG SupabaseClient - Received deeplink with wrong scheme or host
between those two debug logs are mine what is mentioned above

Okay so you can try to print out url.scheme and url.host and check if it matches with your GoTrue configuration? GoTrue checks if the received deeplink host & scheme matches with the provided one in the config:

supabase-kt/GoTrue/src/iosMain/kotlin/io/github/jan/supabase/gotrue/IOS.kt

Lines 11 to 14 in 3bde3ad

	if(url.scheme != gotrue.config.scheme || url.host != gotrue.config.host){
	Napier.d { "Received deeplink with wrong scheme or host" }
	return
	}

ok, you have right, I had wrong configuration in GoTrue, I changed it for correct one, but I am getting exception right now.
KtorSupabaseHttpClient.request[async] - Request failed with TLS sessions are not supported on Native platform. Uncaught Kotlin exception: io.github.jan.supabase.exceptions.HttpRequestException: HTTP request to http://localhost (GET) failed with message: TLS sessions are not supported on Native platform. I think I had same exception when I was trying Email authentication, but on Android works both well. I have issue only for iOS

are you using the darwin ktor engine for ios? If not, try it

[ldobransky]

really thanks for help, it helped :)

No problem! I'll add additional information to the troubleshooting page
